二、识别算法配置参数

# 识别算法全局参数

@float confidence 置信度,范围 0-1
@int frame_event_length 连续多少帧触发报警
@int frame_extract 抽帧频率,多少帧抽取一帧进行识别
@list capture_color 报警图片的框选的颜色数组 如:[255,0,0]
@int capture_size 报警图片的框选的线条粗细
@int record_frame_length 报警时自动截取的视频的长度的一半 推荐为 25(帧数) * 5 = 125

# 识别算法拓展参数

@list area_position 区域坐标,整数,支持多个区域,格式如 [[[10,20],[20,30],[25,16],[99,11]]]
@int area_people 区域内人员最少数量
@list capture_color 区域的框选的颜色数组 RGB
@int capture_size 区域的框选的线条粗细
