+本项目用于在 RK1808/aarch64 设备上运行 YOLOv5 RKNN 推理程序。程序从 RTSP 视频流或 `.h264` 文件读取 H264 数据，通过 FFmpeg 拉流、MPP 解码、RGA 转换为 `640x640 RGB`，再交给 RKNN 执行 YOLOv5 推理，最后将识别结果通过本地 HTTP 接口发给管理程序。

+## 当前版本重点
 
-# reference
+本分支是在 `main` 分支基础上面向现场 RK1808 设备做的稳定性版本，重点解决：
-mpp 硬编码, 从文件中读取yuv一帧图片, 硬编码
 
-该接口也可以直接传入yuv的void*  内存地址, 编码成h264的文件, 具体地址如下
+- 目标设备运行库较旧，需要使用 Linaro GCC 7.4.1 交叉编译，避免引入高版本 `glibc/libstdc++` 依赖。
-https://github.com/MUZLATAN/MPP_ENCODE
+- 支持按时间段控制是否执行推理。
+- 支持 workspace 区域过滤，只上传区域内目标。
+- 优化识别结果上报逻辑，降低多进程运行时漏帧/低置信波动造成的漏报。
+- 增加低置信度、过滤原因、上传决策等日志，便于现场复盘。
 
-## 关于模型的微服务
+## 与 main 分支的区别
-模型目前上传到`./models`目录下，假定模型名为`abc`，则模型文件需要包含`abc.rknn`和`abc.txt`，此时目录结构如下所示：
+
+当前分支相对 `main` 的主要修改点：
+
+- 交叉编译路线固定为 WSL + Linaro GCC 7.4.1。
+- `CMakeLists.txt` 中直接指定 aarch64 Linaro 工具链。
+- 新增 `--time-period` / `-P` 参数，用于配置推理生效时间段。
+- `--threshold` / `-r` 阈值限制为 `30` 到 `90`，即 `0.30` 到 `0.90`。
+- 新增低置信度检测日志和可选截图脚本 `low_conf_snapshot.sh`。
+- 替换旧的连续帧去抖逻辑：
+  - 旧逻辑要求同一数量连续稳定多帧才上传，资源紧张或漏帧时可能上传 `number=0`。
+  - 当前逻辑检测到目标就上传正例 `number > 0`。
+  - 未检测到目标时只记录日志，不主动上传 `number=0`。
+  - 同一最终业务编码 `class_idx` 每 `500ms` 最多上传一次正例。
+  - `0.30 <= prop < threshold` 的弱命中也参与正例上传，用于降低漏报。
+- 修复 h264 分段文件轮转时 `fpSave` 局部变量遮蔽风险，并在退出时关闭文件句柄。
+
+## 模型文件
+
+模型文件放在程序运行目录下，假设模型名为 `abc`，需要准备：
+
+```text
+./abc/abc.rknn
+./abc/abc.txt
+./abc/abc_code.txt
+```
+
+说明：
+
+- `abc.rknn`：RKNN 模型文件。
+- `abc.txt`：类别名称文件，一行一个类别。
+- `abc_code.txt`：类别对应的业务编码，一行一个整数。
+
+如果多个类别在 `abc_code.txt` 中配置成同一个编码，程序上传前会按同一个 `class_idx` 合并数量。
+
+## 编译
+
+详细交叉编译说明见：
+
+```text
+docs/cross_compile_wsl_linaro.md
+```
+
+推荐在 Windows PowerShell 中调用 WSL 编译：

+- RKNN 链接显示 `librknn_api.so`。
+
+## 运行
+
+常用参数：
+
+```text
+-s, --server       RTSP 地址或 h264 文件路径
+-m, --model        模型名，默认 yolov5s
+-c, --camera-id    摄像头 ID，必填
+-t, --type-id      管理程序事件类型
+-p, --upload-port  管理程序本地 HTTP 端口
+-w, --workspace    检测区域，多边形点坐标，逗号分隔
+-r, --threshold    置信度阈值，整数 30 到 90
+-P, --time-period  推理生效时间段
+```
+
+示例：
+
+```bash
+./yolov5 \
+  -s rtsp://127.0.0.1/live \
+  -m abc \
+  -c camera001 \
+  -t 19 \
+  -p 8080 \
+  -r 60
+```
+
+workspace 示例：
+
+```bash
+./yolov5 -s input.h264 -m abc -c camera001 -t 19 -p 8080 -w 100,100,500,100,500,500,100,500
+```
+
+如果不传 `-w`，默认全画面有效。
+
+time-period 示例：
+
+```bash
+./yolov5 -s input.h264 -m abc -c camera001 -t 19 -p 8080 -P 08:00:00-18:00:00
+```
+
+排除某些时间段：
+
+```bash
+./yolov5 -s input.h264 -m abc -c camera001 -t 19 -p 8080 -P '!00:00:00-06:00:00,22:00:00-23:59:59'
+```
+
+## 输出与日志
+
+程序会创建摄像头目录：
+
+```text
+/usr/data/camera/<camera-id>/
+/usr/data/camera/<camera-id>/picsave/
+/usr/data/camera/<camera-id>/frames/
+```
+
+h264 分段文件会写到：
+
+```text
+/usr/data/camera/<camera-id>/<time>.h264
+```
+
+检测日志写在可执行文件同目录：
+
+```text
+.log/YYYY-MM-DD-yolov5.log
+```
+
+日志清理规则：
+
+- 程序启动后第一次写日志会清理旧日志。
+- 程序长期运行跨天后，第一次打开新日期日志时也会清理旧日志。
+- 只清理 `.log` 目录下命名匹配 `YYYY-MM-DD-yolov5.log` 的文件。
+- 默认保留最近约 7 天日志。
+
+常见日志事件：
+
+- `frame_seen`：本次推理帧序号和原始检测数量。
+- `strong_present`：超过阈值且在 workspace 内。
+- `weak_present`：高于 `0.30`、低于阈值且在 workspace 内。
+- `filtered_low_conf`：低于 `0.30`。
+- `filtered_workspace`：不在 workspace 内。
+- `no_target`：本帧没有可上传目标。
+- `upload_positive`：本帧触发正例上传。
+- `upload_skip_throttle`：同一 `class_idx` 500ms 节流跳过。
+- `upload_positive_payload`：实际组装进 JSON 的正例载荷。
+
+如需低置信截图辅助排查，将 `low_conf_snapshot.sh` 放到可执行文件同目录，并确保有执行权限。脚本不存在或不可执行时，主程序仍可正常运行。
+
+## 上报逻辑
+
+程序向本地管理程序发送：
+
+```text
+POST http://127.0.0.1:<upload-port>/video/post
+```
+
+JSON 结构保持兼容：
+
+```json
+{
+  "serial": "camera001",
+  "type": 19,
+  "at": 1778826272,
+  "params": [
+    {
+      "class_idx": 23105,
+      "name": "play",
+      "number": 1
+    }
+  ]
+}
+```
+
+当前版本只主动上传 `number > 0` 的正例。目标未检出时不上传 `number=0`，只写日志。
+
+## G1000 截图通知客户端
+
+推理端的 G1000 主控截图通知客户端代码保存在本仓库根目录：
+
+```text
+snapshot_notify.h
+snapshot_notify.cpp
+```
+
+这两个文件由 `CMakeLists.txt` 编译进 `yolov5`，在 `upload_positive` 日志产生时向主控截图服务发送轻量 UDP 事件。发送结果会追加到同一条检测日志：
+
+```text
+snapshot_notify=ok
+snapshot_notify=failed reason=<err>
+```
+
+截图服务端代码不放在本仓库，独立保存在 `g1000-snapshot-service` 仓库中。

+
+这份文档主要给 Codex 在新聊天里快速恢复上下文用。用户希望中文回复，并希望每次回复末尾带一个简短的“上下文快照”。
+
+## 必须记住
+
+- 项目 Windows 路径：`C:\Users\Smos.DESKTOP-6MT98U8\Desktop\yolov5-inference`
+- WSL 对应路径：`/mnt/c/Users/Smos.DESKTOP-6MT98U8/Desktop/yolov5-inference`
+- 目标平台：aarch64 Linux
+- 目标设备运行库较旧，约为 `GLIBC 2.28`
+- 不要使用过新的 Ubuntu/Debian 交叉工具链，避免产物依赖 `GLIBC_2.33`、`GLIBC_2.34`、`GLIBCXX_3.4.29`
+- 当前使用 Linaro GCC 7.4.1：

+- 工具链必须放在 WSL Linux 文件系统中，不要放在 `/mnt/c/...`，否则符号链接可能损坏并触发 `liblto_plugin.so: file too short`
+- C++ 标准保持 `C++14`
+- RKNN 链接库使用 `rknn_api`，不要改成 `rknnrt`

+# 推理程序去抖与漏报优化记录
+
+本文记录 `time_period_P_r30_linaro` 分支上的去抖和正例上报优化，方便复查代码改动。
+
+## 现场问题
+
+1808 设备上同时运行 6 到 7 个推理程序时，资源紧张会造成推理结果波动。旧逻辑要求同一类别数量连续稳定 3 次才上传，短暂漏检或低置信过滤可能让结果稳定成 `number=0`，随后又上传 `number=1`。
+
+管理程序只处理 `number > 0` 的识别消息，并根据持续时间判断是否触发后续视频合并和上报；目标消失不需要推理程序主动通知。因此推理程序侧不应主动上传 `number=0`。
+
+## 新逻辑
+
+- 当前推理帧只要在 workspace 内检测到可上传目标，就进入正例候选。
+- `prop >= conf_threshold` 记为 `strong_present`。
+- `0.30 <= prop < conf_threshold` 记为 `weak_present`，第一版也参与正例上传，用于降低漏报。
+- `prop < 0.30` 记为 `filtered_low_conf`，不参与上传。
+- workspace 外目标记为 `filtered_workspace`，始终不参与上传。
+- 当前帧无可上传目标时，只记录 `no_target`，不上传 `number=0`。
+
+## 上传节流
+
+同一最终上传编码 `class_idx` 每 `500ms` 最多上传一次正例：
+
+```text
+首次检测到某 class_idx：立即上传
+持续检测到同一 class_idx：每 500ms 最多上传一次
+未检测到：不上报，只记日志
+```
+
+上传 JSON 结构保持不变：
+
+```text
+serial
+type
+at
+params[].class_idx
+params[].name
+params[].number
+```
+
+多个模型 label 如果映射到同一个 `class_idx`，继续合并数量后上传。`codes[i] == 0` 的类别仍不上传。
+
+## 日志字段
+
+本次增加/规范以下日志事件，写入可执行文件目录下 `.log/YYYY-MM-DD-yolov5.log`：
+
+- `frame_seen`：本次推理帧序号和原始检测数量。
+- `strong_present`：超过阈值且在 workspace 内。
+- `weak_present`：高于 0.30、低于阈值且在 workspace 内。
+- `filtered_low_conf`：低于 0.30。
+- `filtered_workspace`：不在 workspace 内。
+- `upload_positive`：本帧触发正例上传。
+- `upload_skip_throttle`：本帧有目标，但 500ms 节流跳过。
+- `upload_skip_code0`：类别编码为 0，按旧规则不上传。
+- `upload_skip_busy`：已有上传线程正在执行，跳过本次上传。
+- `no_target`：本帧没有可上传目标。
+- `upload_positive_payload`：实际组装进 JSON 的正例载荷。
+
+日志清理策略：
+
+- 程序启动后第一次写日志会清理旧日志。
+- 程序长期运行跨天后，第一次打开新日期日志时也会清理旧日志。
+- 只清理 `.log` 目录下命名匹配 `YYYY-MM-DD-yolov5.log` 的文件。
+- 默认保留最近约 7 天日志。
+
+## 额外风险修复
+
+`main.cpp` 中 h264 分段轮转原来在内部重新声明了 `FILE *fpSave`，会遮蔽外层文件句柄。现在改为更新外层 `fpSave`，并在退出主循环后关闭当前句柄。
+
+## 验收场景
+
+- `1,0,1`：上传正例；中间 `0` 只记 `no_target`，不上传 `number=0`。
+- `1,弱命中,1`：弱命中参与正例链路，持续上传或被节流跳过，不归零。
+- `0,0,0`：只记录 `no_target`，不上传。
+- workspace 外目标：只记录 `filtered_workspace`，不上传。
+- 多 label 同 `class_idx`：合并成同一个业务编码上传。
+
+## 编译验证
+
+按 `docs/cross_compile_wsl_linaro.md` 的 WSL + Linaro 路线编译，并检查：
+
+- 产物为 aarch64 ELF。
+- 不依赖 `GLIBC_2.33`、`GLIBC_2.34`、`GLIBCXX_3.4.29`。
+- 仍链接 `librknn_api.so`。

+# 上传链路修复与项目结构说明
+
+## 本次修改
+
+本次修改目标是让推理程序只负责当前帧识别结果上报，不在推理侧处理抖动、持续时间或漏报补偿。
+
+- 只有 `prop >= conf_threshold` 且目标在 workspace 内，才进入 upload 候选。
+- `0.30 <= prop < conf_threshold` 只记录为 `weak_present`，不上传。
+- `prop < 0.30` 只记录为 `filtered_low_conf`，不上传。
+- 低置信截图功能已停用：`maybe_trigger_low_conf_snapshot` 仍保留在代码中，但当前没有调用点。
+- 取消推理侧三帧稳定门槛，抖动和持续时间判断交给管理程序。
+- 取消 500ms upload 节流逻辑，当前帧满足上传条件就尝试上报；如果已有上传线程正在运行，则记录 `upload_skip_busy`。
+- 保留同一 `class_idx` 的多 label 合并上传逻辑。
+- upload 日志保留复查字段：`label`、`number`、`prop`、`box`、`edge_touch`、`left_edge`、`boxes`、`rga`。
+- upload busy 状态改为创建线程前预约、线程结束后释放，避免连续帧在上传线程尚未置位前重复创建多个上传线程。
+
+## 命令行与日志
+
+命令行输出恢复为主分支风格，不再受日志采样影响：
+
+- 低于阈值：`skip prop = ... for class ...`
+- workspace 内且超过阈值：`in result ...`
+- workspace 外：`not in result ...`
+
+日志系统与命令行输出分离：
+
+- `.log` 里的详细检测事件如 `frame_seen`、`strong_present`、`weak_present`、`filtered_workspace`、`filtered_low_conf` 仍按采样策略记录。
+- `upload_positive` 和 `upload_positive_payload` 每次真实上传都会记录。
+- `edge_touch=1` 表示目标框贴到 640x640 模型输入边界，`left_edge=1` 表示贴左边界；这两个字段只用于复查，不影响上传判断。
+- `rga=` 记录最近一次 RGA 输入输出信息，如源宽高、stride、640x640 目标区域和上下填充位置，便于对照 RTSP 现场流和回放视频。
+- `frame=` 是推理回调序号，不等同于主循环中的 `handling [N]th frame`。
+
+## 心跳包
+
+管理程序源码已拉到本地 `rk1808-tool/` 用于对照。
+
+当前管理程序的 `/video/post` 入口在 `rk1808-tool/controllers/report.go`，接收 JSON 结构为：
+
+```text
+serial
+at
+type
+params[].name
+params[].class_idx
+params[].number
+```
+
+推理程序保留 60 秒本地心跳日志，但不再通过 `/video/post` 上传心跳：
+
+- `HEARTBEAT_SECS = 60`
+- 如果 60 秒内没有正例 upload，只记录 `heartbeat_log_only ... upload=0`。
+- 心跳不会生成 `heartbeat_payload`，也不会进入 `/video/post`。
+- 推理程序禁止主动上传 `number=0`；`upload_info` 也会防御性跳过 `total_number <= 0`。
+- 原因：当前 `rk1808-tool` 的 `InsertEvent` 用 `class_idx` 作为全局缓存 key，不区分摄像头；任意摄像头的 `number=0` 都可能取消同一 `class_idx` 的真实事件。
+
+当前这份 `rk1808-tool` 代码里，重启推理程序主要依赖子进程退出后的 `RunAsDaemon` finalizer 触发 `CheckNeedRestart`；未看到独立的“收不到心跳就重启”逻辑。
+
+## 当前项目结构
+
+主要源码：
+
+- `main.cpp`：参数解析、RTSP 读取、视频分段保存、解码主循环。
+- `rknn.cpp` / `rknn.h`：推理回调、检测结果过滤、日志、upload 和心跳逻辑。
+- `yolov5.cc` / `yolov5.h`：RKNN 模型初始化与推理调用。
+- `postprocess.cc` / `postprocess.h`：后处理、label/code 加载。
+- `vertix.cpp` / `vertix.h`：workspace 多边形过滤。
+- `utils.cpp` / `utils.h`：HTTP JSON 上传、时间工具等。
+
+依赖目录：
+
+- `rknn/`：RKNN 头文件和库。
+- `mpp/`：Rockchip MPP 头文件和库。
+- `rga/`：RGA 头文件和库。
+- `ffmpeg/`：FFmpeg 头文件和库。
+- `cjson/`：JSON 处理库。
+

+- `docs/debounce_positive_upload_plan.md`：早期去抖和日志方案记录，仅作历史参考。
