The invention aims to provide an indoor parking lot collision early warning system and early warning method based on a ToF camera, the indoor parking lot collision early warning system based on the ToF camera comprises a ToF camera module, a calculation control module, an early warning module and a power supply module; a ToF camera module, namely a Time-of-Flight, and a flight time camera module, which is a Time-of-Flight camera module; the ToF camera module is installed on the wall face in the advancing direction of a corner or an uphill and downhill position, the distance between the ToF camera module and the ground is 1.5-2 m, and the shooting direction of the ToF camera module vertically faces the ground. According to the method, background point cloud data of a wall and the ground in a camera field angle range is firstly established, then real-time point cloud data is acquired, the background point cloud data and the real-time point cloud data are processed in a calculation control module, the potential collision possibility of a vehicle is calculated, and an external early warning module sends out an audible and visual alarm to remind the vehicle. The possibility of collision between the vehicle and the wall of the parking lot can be effectively reduced.
本发明旨在提供一种基于ToF相机的室内停车场碰撞预警系统及预警方法,基于ToF相机的室内停车场碰撞预警系统,包括ToF相机模组、计算控制模块、预警模块、电源模块;ToF相机模组,即Time‑of‑Flight,飞行时间相机模组;所述的ToF相机模组安装于转角处或者上下坡处前进方向的墙面上,离地面的高度为1.5‑2米,ToF相机模组拍摄方向竖直朝向地面。本发明首先建立相机视场角范围内墙壁和地面的背景点云数据,然后获取实时点云数据,在计算控制模块中对背景点云数据和实时点云数据进行处理,计算车辆潜在的碰撞可能,并通过外部的预警模块发出声光警报提醒车辆,能够有效降低车辆与停车场墙壁发生碰撞的可能。
