Snapshot recognition method, device and system and computer storage medium

Abstract

The invention discloses a snapshot recognition method, device and system and a computer storage medium. The method comprises the steps that initial resolution configuration information is sent to an image sensor through a first communication data line, so that the image sensor is initialized; a plurality of different pieces of pre-cached real-time resolution configuration information are sent to the image sensor according to the time sequence through the first communication data line; control information is sent to the FPGA through a second communication data line, so that the FPGA starts to output a time sequence control signal to the image sensor; the initial resolution configuration information and each piece of real-time resolution configuration information respectively correspond to a unique time sequence control signal; all snapshot picture data generated by the image sensor according to all the time sequence control signals are obtained through the differential data line and recognized. According to the invention, once the image sensor generates the snapshot picture, real-time identification can be carried out, so that the real-time performance is ensured. And a GPU identification card does not need to be inserted into an on-site industrial personal computer for identification, so that the problem of poor stability of the industrial personal computer is avoided.

Description

technical field [0001] The present invention relates to the technical field of ship monitoring, in particular to a snapshot recognition method, device, system and computer storage medium. Background technique [0002] In the field of security monitoring of port and shipping traffic, port and shipping checkpoints are generally located by rivers in the wilderness. For ships passing by the port and shipping checkpoints, it is necessary to monitor their passage at all times, that is, to see the characters on the ship plate or the transported goods. features, which requires that the captured ship pictures be clear and real-time. [0003] In the prior art, generally, an ordinary capture camera is used, and a GPU identification card is inserted into an on-site industrial computer to realize the capture of pictures and the identification of video pictures. It inevitably brings disadvantages such as poor real-time performance, unclear pictures, easy crash of the industrial computer ...

AI Technical Summary

Problems solved by technology

[0005] In the embodiment of the present invention, a snapshot recognition method, device, system and computer storage medium are provided to solve the problem of using a common snapshot camera to capture pictures and videos of ships in the prior art, and inserting a GPU identification card into an on-site industrial computer to realize pictures and videos. identification, resulting in problems such as poor real-time performance, unclear pictures, and poor stability of industrial computer
