-
-## 4. 技术选型
-
-| 类别 | 选型 | 理由 |
-| --- | --- | --- |
-| 开发语言 | Kotlin | Android 官方推荐，协程生态成熟 |
-| UI 框架 | Jetpack Compose（Material 3） | 声明式 UI，开发效率高，叠加层绘制灵活 |
-| 相机 | CameraX（Preview / ImageAnalysis） | Jetpack 官方库，生命周期安全，机型兼容性最佳 |
-| 目标检测模型 | YOLOv8n（自定义 4 类训练） | 精度/速度均衡，端侧部署方案成熟 |

-| 构建 | Gradle（Kotlin DSL）+ AGP 8.x | 现代构建配置 |
-
----
-
-## 5. 核心功能技术方案
-
-### 5.1 实时识别管线
-
-- CameraX 组合：`Preview`（取景）+ `ImageAnalysis`（识别）；
-- `ImageAnalysis` 使用 `STRATEGY_KEEP_ONLY_LATEST` 背压策略，保证不积压帧；
-- 输出格式使用 `OUTPUT_IMAGE_FORMAT_RGBA_8888`（CameraX 1.3+），免去 YUV→RGB 手动转换；
-- **帧节流**：连续模式每 2~3 帧检测一次；标准模式 300ms 一次；省电模式每秒一次（依据设置）；
-- 推理在独立检测线程执行，单例互斥锁防止重叠推理；分析线程不阻塞主线程。
-
-### 5.2 检测叠加层
-
-- Compose Canvas 绘制检测框（矩形 + 类别标签 + 置信度），颜色按类别区分；
-- 检测框内同时标注**大致距离**（如"约 25m"），随检测框实时更新；
-- 距离标注与检测框同生共灭，展示逻辑一致（≥ 0.5s 出现、消失 2s 后移除）；
-- 坐标映射链路：模型归一化坐标 → 旋转校正（sensor rotation）→ 预览视图坐标（含 FIT_CENTER 裁剪偏移修正）；
-- 目标保持 ≥ 0.5s 才展示，避免单帧误检闪烁。
-
-### 5.3 距离标注（单目估计）
-
-- 采用单目针孔模型：`距离 ≈ 焦距px × 物种参考体型 / 检测框像素高度`；
-- 焦距 px 由相机内参换算（`LENS_INFO_AVAILABLE_FOCAL_LENGTHS` × `SENSOR_INFO_PHYSICAL_SIZE`），个别机型回退用视场角推算；
-- 物种参考体型内置表（见 6.1），每类一个平均体型值；
-- 展示为"约 X m"；5~50m 范围误差预期 ≤ ±30%；
-- 纯算术运算，无额外模型与算力开销；V2 可引入地面平面法（设备俯仰角 + 相机高度）提升精度。
-
-### 5.4 检测提醒
-
-- 检测到目标时触发震动 / 提示音，用户可开关；
-- 防重复打扰：10s 内同类目标只提醒一次；
-- 目标消失后 2s 内不闪断显示，避免频繁提醒。
-
-### 5.5 低光增强（P2）
-
-- 简单直方图均衡 / 亮度增益提升低光帧可见度；
-- V2 可引入夜视增强网络思路。
-
----
-
-## 6. AI 模型方案（核心）
-
-### 6.1 目标类别定义
-
-| 类别 ID | 英文标签 | 中文名 | 涵盖范围 | 参考体型（距离估计用） |
-| --- | --- | --- | --- | --- |
-| 0 | pheasant | 野鸡 | 环颈雉等雉类 | ≈ 0.45m（身高） |
-| 1 | cover | 生境区域 | 草丛 / 灌木 / 水面等疑似生境（黄色虚线框预警，F08） | ≈ 0.5m（参考植被高度） |
-
-### 6.2 模型选型对比
-
-| 模型 | 输入尺寸 | 中端机单帧耗时（GPU） | 精度 | 说明 |
-| --- | --- | --- | --- | --- |
-| **YOLOv8n（推荐）** | 320~640 | 约 30~80ms | 高 | 支持自定义类别训练，精度/速度平衡 |
-| EfficientDet-Lite0/2 | 320 | 约 20~50ms | 中 | 仅 COCO 预置类别 |
-| YOLOv5s | 640 | 约 80~150ms | 高 | 体积与耗电偏大 |
-| SSD MobileNetV2 | 300 | 约 15~30ms | 低 | 小目标与远距离效果差 |
-
-**结论**：选用 **YOLOv8n**，使用预训练权重迁移学习自定义训练，导出 TFLite 端侧部署。
-
-### 6.3 数据集方案
-
-| 项 | 方案 |
-| --- | --- |
-| 数据量 | 1000~2000 张（首版可 500+ 起步，滚动补充） |
-| 多样性 | 覆盖不同季节、晨昏/正午/逆光、远近距离、姿态、遮挡、背景（草丛/农田/林地/雪地） |
-| 标注 | 人工标注（LabelImg 等工具），YOLO 格式（class, cx, cy, w, h） |
-| 生境标注 | 人工标注可疑度最高的藏身点（cover 类，黄色框，约占画面 2%~15%），综合植被密度 / 地形 / 光线判断 |
-| 数据增强 | Mosaic、MixUp、HSV 扰动、随机翻转、随机缩放裁剪 |
-| 数据划分 | train 80% / val 10% / test 10% |
-| 负样本 | 补充无目标场景图，控制误检 |
-
-### 6.4 训练方案
-
-- 框架：ultralytics YOLOv8，预训练权重 `yolov8n.pt` 迁移学习；
-- 超参：imgsz=640（训练）、epochs 100~200（早停）、batch 16~32（视 GPU 而定）；
-- 评估指标：
- - mAP@0.5 ≥ **0.85**（达标线 0.80）；
- - mAP@0.5:0.95 ≥ **0.55**；
- - 负样本误检率 ≤ **2%**；
- - 远距离小目标（高度 ≤ 20px）召回率 ≥ **60%**。
-
-### 6.5 模型转换与量化
-
-- 导出命令：`yolo export model=best.pt format=tflite imgsz=320`；
-- 量化策略：
- - 优先 **fp16**（配合 GPU Delegate，精度损失小）；
- - 低端机 / CPU 场景使用 **int8** 量化（体积更小、CPU 更快）；
-- 输入尺寸：320×320（连续检测）/ 416×416（远距离模式，V2）。
-
-### 6.6 推理优化
-
-- GPU Delegate 优先，初始化失败自动回退 CPU（NNAPI 可选）；
-- 推理线程 4 线程，首次推理前执行预热（dummy run）；
-- 输入输出 ByteBuffer / Bitmap 复用，避免热路径频繁分配。
-
-### 6.7 精度与速度目标

-
-## 3. 模块设计
-
-### 3.1 camera 模块 — CameraController.kt
-
-职责：创建并绑定 CameraX 用例（Preview + ImageAnalysis），统一生命周期。
-
-```kotlin
-class CameraController(
- private val lifecycleOwner: LifecycleOwner,
- private val analysisExecutor: Executor,
-) {
- private lateinit var cameraProvider: ProcessCameraProvider
- private lateinit var imageAnalysis: ImageAnalysis
-
- fun start(previewView: PreviewView, analyzer: ImageAnalysis.Analyzer) {
- val future = ProcessCameraProvider.getInstance(previewView.context)
- future.addListener({
- cameraProvider = future.get()
-
- val preview = Preview.Builder().build().also {
- it.surfaceProvider = previewView.surfaceProvider
- }
-
- imageAnalysis = ImageAnalysis.Builder()
- .setBackpressureStrategy(ImageAnalysis.STRATEGY_KEEP_ONLY_LATEST)
- .setOutputImageFormat(ImageAnalysis.OUTPUT_IMAGE_FORMAT_RGBA_8888)
- .build()
- imageAnalysis.setAnalyzer(analysisExecutor, analyzer)
-
- cameraProvider.bindToLifecycle(
- lifecycleOwner,
- CameraSelector.DEFAULT_BACK_CAMERA,
- preview, imageAnalysis,
- )
- }, ContextCompat.getMainExecutor(previewView.context))
- }
-}
-```
-
-要点：
-
-- `OUTPUT_IMAGE_FORMAT_RGBA_8888`（CameraX 1.3+）直接得到 RGBA 图像，免 YUV 转换；
-- `STRATEGY_KEEP_ONLY_LATEST`：分析器忙时丢弃旧帧，不积压；
-- 相机权限检查与请求在进入本模块前完成；
-- 前后摄切换：重新以对应 `CameraSelector` 执行 `bindToLifecycle`（解绑旧用例）。
-
-### 3.2 camera 模块 — FrameAnalyzer.kt
-
-职责：帧节流、旋转获取、调度检测、结果回调。
-
-```kotlin
-class FrameAnalyzer(
- private val detector: Detector,
- private val onResult: (List, Int) -> Unit, // 结果 + 旋转角
-) : ImageAnalysis.Analyzer {
-
- private var lastDetectMs = 0L
-
- override fun analyze(imageProxy: ImageProxy) {
- val now = SystemClock.elapsedRealtime()
- val interval = frameIntervalMs() // 依据设置：连续/标准/省电
- if (now - lastDetectMs < interval) {
- imageProxy.close(); return
- }
- lastDetectMs = now
-
- val bitmap = imageProxy.toBitmap() // RGBA_8888 直接转 Bitmap
- val rotation = imageProxy.imageInfo.rotationDegrees
- try {
- val results = detector.detect(bitmap)
- onResult(results, rotation)
- } finally {
- imageProxy.close() // 必须关闭，否则阻塞流
- }
- }
-}
-```
-
-### 3.3 detection 模块 — Detector 接口
-
-```kotlin
-interface Detector {
- /** 输入 RGBA 位图，输出归一化坐标检测结果（0..1） */
- fun detect(bitmap: Bitmap): List
-}
-```
-
-### 3.4 detection 模块 — TFLiteDetector.kt
-
-```kotlin
-class TFLiteDetector(
- context: Context,
- private val inputSize: Int = 320,
- private val confThreshold: Float = 0.40f, // 动物类阈值
- private val habitatThreshold: Float = 0.35f, // 生境区域阈值
- private val iouThreshold: Float = 0.45f,
- gpuEnabled: Boolean = true,
-) : Detector {
-
- private val labels: List =
- context.assets.open("labels.txt").bufferedReader().readLines()
-
- private val interpreter: Interpreter = Interpreter(
- loadModelFile(context, "model.tflite"),
- Interpreter.Options().apply {
- setNumThreads(4)
- if (gpuEnabled) {
- try { addDelegate(GpuDelegate()) } catch (_: Exception) { /* 回退 CPU */ }
- }
- },
- )
-
- private val inputBuffer: ByteBuffer = ByteBuffer.allocateDirect(
- 1 * inputSize * inputSize * 3 * 4 // float32
- ).order(ByteOrder.nativeOrder())
-
- private val outputBuffer: ByteBuffer = ByteBuffer.allocateDirect(
- OUTPUT_ELEMENTS * 4
- ).order(ByteOrder.nativeOrder())
-
- override fun detect(bitmap: Bitmap): List {
- preprocess(bitmap, inputBuffer) // 缩放 + RGB 归一化 → 输入缓冲
- interpreter.run(inputBuffer, outputBuffer) // 单张推理
- return postprocess(outputBuffer, bitmap.width, bitmap.height)
- }
-}
-```
-
-输入 / 输出规格（YOLOv8n 四类，320 输入）：
-
-- 输入：`[1, 320, 320, 3]`，RGB，float32 归一化 0~1；
-- 输出：`[1, 9, 8400]`（8400 = 各尺度 anchor 数，9 = 4 个框坐标 cx/cy/w/h + 5 类得分），展平为 `9 * 8400` 个 float。
-
-### 3.5 detection 模块 — 后处理（解码 + NMS）
-
-```kotlin
-private fun postprocess(raw: FloatArray, imgW: Int, imgH: Int): List {
- val numAnchor = raw.size / 9
- val boxes = mutableListOf()
-
- for (a in 0 until numAnchor) {
- val cx = raw[a]; val cy = raw[9 + a]
- val w = raw[18 + a]; val h = raw[27 + a]
- var bestCls = 0; var bestScore = 0f
- for (c in 0 until 5) {
- val s = raw[36 + c * numAnchor + a] // 类别得分按 anchor 平铺
- if (s > bestScore) { bestScore = s; bestCls = c }
- }
- if (bestScore < confThreshold) continue
- boxes += DetectionResult(
- label = labels[bestCls],
- score = bestScore,
- // 归一化坐标（裁剪到 [0,1]）
- left = (cx - w / 2).coerceIn(0f, 1f),
- top = (cy - h / 2).coerceIn(0f, 1f),
- right = (cx + w / 2).coerceIn(0f, 1f),
- bottom = (cy + h / 2).coerceIn(0f, 1f),
- )
- }
- return nms(boxes, iouThreshold)
-}
-
-fun nms(boxes: List, iouThreshold: Float): List {
- val sorted = boxes.sortedByDescending { it.score }
- val kept = mutableListOf()
- for (b in sorted) {
- if (kept.none { iou(b, it) > iouThreshold }) kept += b
- }
- return kept
-}
-```
-
-注意：以上取数索引为示意，**必须与模型导出时的输出布局（yolov8 tflite 为 9×8400，按列平铺）核对一致**，建议训练导出后用 Python 脚本先对单图做一致性校验再接入 App。
-
-### 3.6 distance 模块 — DistanceEstimator.kt
-
-```kotlin
-class DistanceEstimator(context: Context) {
-
- private val cameraManager = context.getSystemService(Context.CAMERA_SERVICE) as CameraManager
- private var focalPxCache = -1f
-
- // 物种参考体型（米），用于针孔模型估算
- private val speciesSizeM = mapOf(
- "pheasant" to 0.45f, // 身高
- )
-
- /** 距离 = 焦距px × 参考体型 / 框高px（在分析图像分辨率下计算） */
- fun estimate(label: String, boxHeightNorm: Float, imageHeightPx: Int): Float? {
- val realH = speciesSizeM[label] ?: return null
- val boxH = boxHeightNorm * imageHeightPx
- if (boxH < 8f) return null // 过小目标不估算
- val focalPx = focalPx(imageHeightPx)
- if (focalPx <= 0) return null
- return round(focalPx * realH / boxH)
- }
-
- /** focal_px = focal_mm × (imageHeightPx / sensorHeightMm)；视场角作回退 */
- private fun focalPx(imageHeightPx: Int): Float {
- if (focalPxCache > 0) return focalPxCache
- val c = cameraManager.getCameraCharacteristics(cameraManager.cameraIdList.first())
- val focalMm = c.get(CameraCharacteristics.LENS_INFO_AVAILABLE_FOCAL_LENGTHS)?.firstOrNull()
- val sensor = c.get(CameraCharacteristics.SENSOR_INFO_PHYSICAL_SIZE)
- val fov = c.get(CameraCharacteristics.LENS_INFO_HORIZONTAL_VIEW_ANGLE)
- focalPxCache = when {
- focalMm != null && sensor != null -> focalMm * imageHeightPx / sensor.height
- fov != null -> (imageHeightPx / 2f) / tan(fov / 2f)
- else -> -1f
- }
- return focalPxCache
- }
-}
-```
-
-说明：
-
-- 前后摄切换时需按当前相机重新获取焦距（缓存按相机 ID 区分）；
-- 距离估算仅供参考，实际距离可能因环境因素有所偏差。
-
-### 3.7 detection 模块 — CoordinateMapper.kt
-
-模型输出为归一化坐标（相对分析图像，竖屏方向），需转换到预览视图坐标：
-
-```kotlin
-class CoordinateMapper(private val view: PreviewView) {
-
- /** 归一化坐标 → 预览视图像素坐标（考虑传感器旋转与 FIT_CENTER 裁剪） */
- fun mapToView(norm: DetectionResult, rotation: Int): RectF {
- // 1) 旋转校正：把"图像方向"归一化坐标转到"竖屏视图方向"
- val (x0, y0, x1, y1) = rotate(norm, rotation)
- // 2) 处理 FIT_CENTER 的裁剪偏移与缩放
- val viewW = view.width; val viewH = view.height
- val scale = min(viewW / bitmapW, viewH / bitmapH) // bitmap 尺寸
- val offsetX = (viewW - bitmapW * scale) / 2f
- val offsetY = (viewH - bitmapH * scale) / 2f
- return RectF(
- x0 * bitmapW * scale + offsetX,
- y0 * bitmapH * scale + offsetY,
- x1 * bitmapW * scale + offsetX,
- y1 * bitmapH * scale + offsetY,
- )
- }
-}
-```
-
-### 3.8 overlay 模块 — DetectionOverlay.kt
-
-Compose Canvas 叠加层：
-
-```kotlin
-@Composable
-fun DetectionOverlay(results: List, rotation: Int, modifier: Modifier) {
- val mapper = remember { CoordinateMapper(view) }
- Canvas(modifier = modifier) {
- results.forEach { r ->
- val rect = mapper.mapToView(r, rotation)
- drawRect(
- color = colorOf(r.label),
- topLeft = Offset(rect.left, rect.top),
- size = Size(rect.width(), rect.height()),
- style = Stroke(6.dp.toPx()),
- )
- // 距离由 ViewModel 计算后写入 DetectionResult.distance（Float?）
- val dist = r.distance?.let { " · 约${it}m" } ?: ""
- drawText("${r.label} ${(r.score * 100).toInt()}%$dist")
- }
- }
-}
-```
-
-防闪烁：ViewModel 中对结果做"目标停留 ≥ 0.5s 才显示、消失 2s 后移除"的平滑处理。
-
-### 3.9 reminder 模块 — Reminder.kt
-
-```kotlin
-class Reminder(private val context: Context) {
- private val vibrator = context.getSystemService(Vibrator::class.java)
- private var lastAlertAt = 0L
- private var lastAlertLabel: String? = null
-
- /** 同类目标 10s 内只提醒一次 */
- fun onDetected(label: String) {
- val now = SystemClock.elapsedRealtime()
- if (label == lastAlertLabel && now - lastAlertAt < 10_000) return
- lastAlertAt = now
- lastAlertLabel = label
- vibrator?.vibrate(VibrationEffect.createOneShot(200, VibrationEffect.DEFAULT_AMPLITUDE))
- }
-}
-```
-
-### 3.10 设置存储 — DataStore
-
-使用 DataStore Preferences 保存：`conf_threshold`（默认 0.40）、`detect_mode`（连续/标准/省电）、`vibrate_enabled`、`sound_enabled`、`low_light_enhance`（P2）、`show_distance`（默认开）。`SettingsViewModel` 以 Flow 暴露，`FrameAnalyzer` 与 `TFLiteDetector` 读取最新值。
-
----
-
-## 4. 关键流程实现
-
-### 4.1 启动流程
-
-```
-MainActivity.onCreate
-→ 检查/请求 CAMERA 权限
-→ 初始化 TFLiteDetector（后台线程，含预热推理）
-→ CameraController.start(previewView, analyzer)
-→ ViewModel 订阅检测结果 → 叠加层渲染 + 提醒触发
-```
-
-预热：加载模型后执行一次空推理（全零输入），避免首帧卡顿。
-
-### 4.2 帧节流与并发控制
-
-- 检测间隔：连续 80~100ms / 标准 300ms / 省电 1000ms（由设置决定）；
-- 推理在单线程 Executor（HandlerThread）串行执行，天然互斥；
-- 分析线程只做"取帧 → 判断节流 → 提交任务"，不做推理，保证预览流畅。
-
-### 4.3 提醒、距离标注与防闪烁
-
-- 检测到目标（置信度 ≥ 阈值，生境区域用独立阈值）→ `Reminder.onDetected(label)`，10s 防重复，动物与生境预警提醒方式区分；
-- 叠加层展示逻辑：目标连续出现 ≥ 0.5s 才绘制；消失后 2s 内不清除，避免闪烁；
-- 低置信度结果（阈值以下）不展示、不提醒；
-- 距离标注：结果到达后调用 `DistanceEstimator` 估算"约 X m"，随检测框渲染（FrameAnalyzer 回调携带分析图像高度）；生境区域同样估算（按参考植被高度，误差较大）；框高过小（< 8px）或无法获取焦距显示"--"。
-
----
-
-## 5. 模型集成细节
-
-| 项 | 说明 |
-| --- | --- |
-| 模型文件 | `app/src/main/assets/model.tflite`，随 APK 打包 |
-| 标签文件 | `assets/labels.txt`，每行一个类别，顺序与训练一致（pheasant） |
-| 量化 | 优先 fp16（GPU）；int8 用于 CPU/低端机回退 |
-| 加载 | `Interpreter(loadAssetFile(...))`，进程内单例 |
-| 预热 | 初始化后执行一次 dummy run |
-| 校验 | 发布前用 Python 脚本（tflite-runtime）对测试集抽样验证模型输出布局与 App 解析一致 |
-
----
-
-## 6. 性能优化实践
-
-| 手段 | 说明 |
-| --- | --- |
-| GPU Delegate | 优先启用；`addDelegate` 抛异常或首帧异常时回退 CPU，并上报降级日志 |
-| 输入缓冲复用 | ByteBuffer 复用，避免每次检测重新分配 |
-| 帧节流 | 按模式降频，KEEP_ONLY_LATEST 不积压 |
-| 位图复用 | ImageProxy → Bitmap 走共享缓冲；叠加层仅绘制检测框，不复制整帧 |
-| 线程模型 | 检测线程单线程串行；UI 线程零推理 |
-| 低分辨率检测 | 320 输入检测；远距离模式可切 416（V2） |
-| 距离标注 | 纯算术运算开销可忽略；焦距 px 按相机缓存复用，避免重复查询 CameraCharacteristics |
-| 生命周期 | 后台自动 `unbind` 相机释放资源，避免耗电 |
-| 省电模式 | 降到 1 帧/秒 + 低分辨率 + 关闭提醒以外的动画 |
-
----
-
-## 7. 异常与降级策略
-
-| 异常场景 | 处理 |
-| --- | --- |
-| GPU 不可用 / 模型加载失败 | 回退 CPU 线程数调整；失败则提示"识别不可用"但不影响相机预览 |
-| 相机初始化失败（个别机型） | 重试一次 → 失败提示并引导检查权限/重启 |
-| 权限被拒 | 引导页说明用途，提供跳转系统设置 |
-| 低内存 | 主动释放缓存位图，降低检测分辨率 |
-| 推理超时（> 500ms） | 丢弃该帧结果，恢复下一帧，保证预览流畅 |
-| 无法读取焦距 / 视场角（个别机型） | 距离显示"--"，识别不受影响 |
-
----
-
-## 8. 测试方案
-
-### 8.1 单元测试（JUnit）
-
-- `NmsTest`：NMS 正确性（重叠/多类别/边界框）；
-- `CoordinateMapperTest`：四向旋转映射、FIT_CENTER 裁剪偏移；
-- `ThresholdTest`：置信度阈值过滤逻辑；
-- `ReminderTest`：10s 防重复提醒逻辑、动物与生境提醒方式区分；
-- `DistanceEstimatorTest`：焦距换算、距离公式、过小目标不估算、生境区域按植被高度估算。
-
-### 8.2 模型评估（Python 脚本，独立于 App）
-
-- 对测试集计算 mAP@0.5、mAP@0.5:0.95、各类别 AP、负样本误检率；
-- 输出混淆矩阵，分析检测精度。
-
-### 8.3 仪器测试（androidTest）
-
-- 模拟帧注入：将测试图片经 `ImageProxy` 注入分析器，断言结果（不依赖真机取景）；
-- 权限拒绝 / 恢复场景；
-- 冷启动到预览的时间基准测试。
-
-### 8.4 真机测试矩阵
-
-| 机型档位 | 代表机型 | 验证项 |
-| --- | --- | --- |
-| 旗舰 | 骁龙 8 系 / 麒麟 9 系 | 全功能、GPU 路径、长时间发热 |
-| 中端 | 骁龙 7 系 / 天玑 8 系 | 延迟 ≤ 80ms、耗电 ≤ 15%/h |
-| 低端 | 骁龙 4 系 / 天玑 6 系 | CPU 回退路径、省电模式可用性 |
-

-
-## 9. 构建与发布
-
-```kotlin
-android {
- compileSdk = 35
- defaultConfig {
- applicationId = "com.example.observer"
- minSdk = 24
- targetSdk = 35
- ndk { abiFilters += listOf("arm64-v8a") } // 主发 arm64；如需兼容 32 位另发包
- }
- buildTypes {
- release {
- isMinifyEnabled = true
- isShrinkResources = true
- proguardFiles(getDefaultProguardFile("proguard-android-optimize.txt"), "proguard-rules.pro")
- }
- }
-}
-```
-
-- R8 规则：保留 TFLite 相关类（`-keep class org.tensorflow.** { *; }`），assets 模型不混淆；
-- 签名：正式签名 + Gradle 管理（或环境变量注入），不上传 keystore 到仓库；
-- 上架检查：隐私政策（仅相机权限、不采集与存储数据声明）、权限用途说明。
-
----
-
-## 10. 后续演进（V2 方向）
-
-- 更多物种类别（哺乳类、鸟类细分），支持模型远程更新；
-- 小目标优化：SAHI 切图推理 / 专用小目标模型 / 数字变焦辅助；
-- 夜视 / 红外增强模式；
-- 检测结果语音播报，提升无障碍体验；
-- 距离精度增强：基于设备俯仰角与相机高度的地面平面法、镜头畸变校正、水下折射修正；
-- 生境类别细分与精度提升（湿地、林缘等），生境预警策略优化；
-- 若未来需要留存能力（拍照、记录），可基于现有检测链路平滑扩展。

+# observer
+
+野生动物实时识别 App（Flutter 版）。Android / iOS 一套代码，后端接口与支付见
+[`docs/PaymentApi.md`](docs/PaymentApi.md)。
+
+## iOS 真机部署（iPhone）
+
+### 构建与安装
+
+```bash
+# 真机必须传 Mac 局域网 IP：默认 API_BASE_URL 是 10.0.2.2（仅 Android 模拟器可用），
+# 不传则 iPhone 上所有网络请求（登录/授权/套餐）都会失败
+flutter build ios --release --dart-define=API_BASE_URL=http://:8080
+
+# 安装到真机（UDID 可用 `xcrun devicectl list devices` 查询）
+xcrun devicectl device install app --device build/ios/iphoneos/Runner.app
+
+# 启动并抓控制台日志（--terminate-existing 先杀掉旧实例）
+xcrun devicectl device process launch --console --terminate-existing \
+ --device com.observer.app
+```
+
+### 注意事项（踩过的坑）
+
+- **debug 构建不能在真机上从桌面图标启动**：iOS 14+ 会提示
+ "In iOS 14+, debug mode Flutter apps can only be launched from Flutter tooling"。
+ debug 调试必须用 `flutter run -d <设备ID>` 或 Xcode IDE 启动（`flutter devices` 查设备ID）；
+ 从图标启动只对 release 构建有效。
+- **模型输入是 NHWC**：`assets/model.tflite` 做过字节级手术（开头 TRANSPOSE→RESHAPE，
+ 输入 [1,320,320,3]），改动记录见 git 历史，重导模型需同步处理，否则 iOS 报
+ "Node number 0 (TRANSPOSE) failed to prepare"。
+- **模拟器黑屏**：本机 iOS 模拟器 Impeller 渲染黑屏，验证 UI 用 VM service
+ （`flutter run` 输出里的 DevTools 地址），或直接真机验证。
