功能介绍

微卡口业务：在机动车进入智能感知范围时，抓取机动车相关信息进行上报的智能场景。

微卡口业务消息体的message_type值为micro_checkpoint_data。

目前行业视频管理服务会处理以下场景：

itgt_type/target_type枚举值：

• 51 微卡口（摄像机SDC/NVR800开启微卡口/车辆智能下的功能，机动车进去区域且触发违法停车、非机动车占用机动车道、机动车占用非机动车道、逆行/倒车、压线等事件，则会被抓拍且分析出目标行为和特征信息，如：品牌、款式、主/副驾驶的情况，包括有无打电话、有无系安全带、有无遮阳板等）
• 52 微卡口车流量统计（摄像机SDC/NVR800开启微卡口/车辆智能下的交通流量统计功能，机动车进入区域则会被统计分析，最后得到统计分析结果，如：车辆计数、车辆平均速度、车流密度等）
