Problems solved by technology
[0003] Because traffic signals and cameras usually belong to different manufacturers and do not interact with each other, it is difficult to align the clocks. Therefore, the time stamp of the traffic light signal output by the traffic signal will actually be aligned with the time stamp in the video captured by the camera. Inaccurate situation
At this time, when using traffic light signals and cameras to collect video for traffic data calculation, the results are usually inaccurate, especially in the control of intelligent traffic, which will further affect the design of subsequent solutions

The invention discloses a signal lamp control method and device and computer equipment, and relates to the technical field of intelligent transportation. The specific implementation scheme is as follows: acquiring a monitoring video of an intersection, determining an intersection signal lamp control period according to a signal lamp state presented by each frame of image in the monitoring video and an acquisition moment of each frame of image, performing statistics according to each frame of image acquired in the same period to obtain a traffic index of a corresponding period, and controllinga signal lamp of the intersection according to the traffic index. After determining the intersection signal lamp control period, intersection traffic indexes are obtained periodically, signal lamps atthe intersection are controlled according to the traffic indexes. The traffic indexes in the period can accurately reflect the traffic condition of the intersection in the corresponding period; therefore, the control scheme for controlling the signal lamp at the intersection is more accurate, and meanwhile, the signal lamp is controlled based on the monitoring video of the intersection, so that the process of aligning the timestamp of the traffic signal machine with the timestamp of the camera in related technologies is avoided, and the time is saved to a certain extent.
Description
technical field [0001] The present application relates to the field of transportation, specifically to the field of intelligent transportation technology, and in particular to a signal light control method, device, computer equipment and non-transitory computer-readable storage medium storing computer instructions. Background technique [0002] At the intersection of current traffic roads, there are usually traffic lights and cameras for photographing the traffic road surface. Wherein, the transformation of the traffic light is controlled by the traffic signal machine. [0003] Because traffic signals and cameras usually belong to different manufacturers and do not interact with each other, it is difficult to align the clocks. Therefore, the time stamp of the traffic light signal output by the traffic signal will actually be aligned with the time stamp in the video captured by the camera. Inaccurate situation. At this time, when using traffic light signals and cameras to c...
