Snapshot recognition method, device, system and computer storage medium

Abstract

The invention discloses a snapshot recognition method, a device, a system and a computer storage medium. The method comprises the steps that initialization configuration information is sent to an image sensor through a first communication data line, so that the image sensor is initialized; the image sensor works in different working modes according to different initial configuration information; each working mode corresponds to the resolution of one captured picture, wherein the resolution ratio can reach 8K (7680 * 4320), so that the captured picture is very clear; the control information is sent to a field programmable gate array (FPGA) through a second communication data line, so that the FPGA starts to output a time sequence control signal to an image sensor; and acquiring snapshot picture data generated by the image sensor according to the time sequence control signal through the differential data line, and recognizing the snapshot picture data. According to the invention, once the image sensor generates the snapshot picture, real-time recognition can be carried out, so that the real-time performance is ensured. A GPU recognition card does not need to be inserted into an on-site industrial personal computer for recognition, 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
