The invention discloses a traffic flow detector of a traffic signal lamp based on fusion TOF distance measurement, which comprises a DTOF distance measurement module and a traffic signal lamp, and is characterized in that the DTOF distance measurement module is installed at the bottom of the traffic signal lamp, the bottom surface of the DTOF distance measurement module is symmetrically provided with two launch canisters, the top surface of the DTOF distance measurement module is fixedly provided with a U-shaped seat, and the U-shaped seat is fixedly provided with a TOF distance measurement module. Two clamping plates are movably arranged on each of the front surface and the rear surface of the U-shaped seat; the DTOF distance measurement module is installed at the bottom of a common traffic signal lamp, light signals are emitted vertically downwards on the ground, the distance measurement function is achieved and used for distinguishing whether objects pass or not, whether vehicles pass or not is further determined, the traffic flow detection function is achieved, the equipment cost can be greatly reduced, and the traffic flow detection efficiency is improved. The method can be used as a comprehensive supplement of a forward radar and video detection mode, traces the key flow direction path, the gathering speed and the traffic volume, accurately senses the road traffic operation condition in real time, and accurately discovers traffic jam points in time.
本发明公开了基于融合TOF测距的交通信号灯的车流量检测器,包括DTOF测距模组和交通信号灯,所述DTOF测距模组安装在交通信号灯的底部,且DTOF测距模组的底部表面对称设置有两个发射筒,所述DTOF测距模组的顶部表面固定有U形座,且所述U形座的前后表面均活动设置有两个卡板;通过将DTOF测距模组安装在普通交通信号灯的底部,采用垂直向下于地面的方式发射光信号,实现测距功能用于分辨是否有物体通过,从而进一步确定是否有车辆通过,来实现车流量的检测功能,可以极大的降低设备成本,可作为正向雷达、视频检测方式的全面综合补充,溯源关键流向路径及集聚速度和通行量,实时精准感知道路交通运行状况、及时准确发现交通拥堵点。
