Problems solved by technology

[0004] However, the target detection of the video captured by the video capture device can only recognize the vehicle, and cannot judge whether the driving direction of the vehicle is driving in or driving out, so it is impossible to realize the function of capturing only vehicles in a certain driving direction

Abstract

The embodiment of the invention provides a radar-based snapshot triggering system, a method and a device. The system comprises an image collection device and a radar connected with the image collection device, the radar is provided with at least two detection regions, and each two detection regions are spaced by a preset distance; the radar detects whether a target object exists in each detection area, and sends a detection result corresponding to the detection area to the image collection equipment when the target object enters or leaves each detection area; the image collection device determines the moving direction of the target object according to the received at least two detection results and the receiving time of each detection result; If the moving direction of the target object is the preset moving direction, shooting the target object to obtain a snapshot image containing the target object. The moving direction of the target object is determined according to the detection results of the at least two radars and the preset moving direction judgment rule, so that the target object in a single moving direction can be captured.

Description

technical field [0001] The present application relates to the technical field of video surveillance, in particular to a radar-based capture trigger system, method and device. Background technique [0002] In order to facilitate the management of vehicles entering and exiting public places, image acquisition equipment can be installed at the mixed traffic entrances and exits of public places. Shoot to get a snapshot image containing the vehicle. Among them, in public places such as parking lots and industrial parks, mixed traffic entrances and exits are barrier gates shared by vehicles entering and exiting public places. [0003] In related technologies, a video capture device can be installed at the entrance and exit of mixed traffic, and the video capture device can shoot the scene at the entrance and exit of mixed traffic, and then perform target detection on the captured video, and trigger shooting if a vehicle is detected mode, to capture the current scene to obtain a ...
