[0002] The video monitoring system in the prior art usually has a direct display monitor, which is viewed by security personnel in real time, and at the same time, video recording is used to keep a certain amount of monitoring video for future reference. During the real-time viewing process, due to the single screen, it is easy to get tired, and the The video not only takes up a large storage space, but also requires a lot of work and time-consuming when reviewing manual screening. There is an urgent need for a monitoring method that can intelligently remind security personnel of the information that needs attention, and intelligently compress the video to retain only useful information.

Embodiment
[0012] Embodiment: the method for compressing video in and out of a parking lot based on infrared gratings in this embodiment includes the following steps:
[0013] 1) Install infrared gratings at the entrance and exit of the existing parking lot;
[0014] 2) Connect the signal output end of the infrared grating to the control device of the existing parking lot monitoring system;
[0015] 3) Execute the compression software in the control device of the existing parking lot monitoring system. The compression software collects the signal output by the infrared grating to record the time when vehicles pass by at the entrance and exit, and sends the control signal to the monitor of the parking lot monitoring system. Increase the brightness of the image displayed on the monitor;
[0016] 4) The compression software extracts the video in the memory of the parking lot monitoring system, selects the time point of the vehicle passing in step 3) and saves the video for 1 to 3 minutes b...

The invention discloses a parking lot entrance and exit video compression method based on echelette gratings. The method includes steps of installing echelette gratings at an entrance and an exist of a prior parking lot, connecting signal output ends of the echelette gratings to a control device of a prior parking-lot monitoring system, acquiring signals output by the echelette gratings as to record the times when vehicles pass the entrance and the exist and extracting videos at corresponding times in a storage and the like. The parking lot entrance and exit video compression method based on the echelette gratings has the advantages of being high in detection rate and capable of saving search time and storage space.
Description
technical field [0001] The invention relates to an image processing method, in particular to an infrared grating-based video compression method for entering and exiting a parking lot. Background technique [0002] The video monitoring system in the prior art usually has a direct display monitor, which is viewed by security personnel in real time, and at the same time, video recording is used to keep a certain amount of monitoring video for future reference. During the real-time viewing process, due to the single screen, it is easy to get tired, and the The video not only takes up a large storage space, but also requires a lot of work and time-consuming when reviewing manual screening. There is an urgent need for a monitoring method that can intelligently remind security personnel of the information that needs attention, and intelligently compress the video to retain only useful information. . Contents of the invention [0003] Purpose of the invention: In order to overcom...
