Front-end acquisition device of contour video monitoring system

Abstract

The invention relates to a front-end acquisition device of a contour video monitoring system. The device comprises a photoelectric sensor group used for acquiring contour information, wherein the output end of the photoelectric sensor group is connected with the input end of a field programmable gate array (FPGA) controller; the input end of the FPGA controller is also connected with the output ends of a crystal oscillator circuit, a configuration downloading circuit and a reset circuit respectively; and the output end of the FPGA controller is connected with a serial port circuit. The contour characteristics of different types of objects are acquired through the photoelectric sensor group, the signal data acquired by the photoelectric sensor group is received by the FPGA controller, the serial port circuit is arranged, the signal data is transmitted into a computer terminal through the serial port circuit to be processed and identified, and finally, video monitoring on the different types of objects is realized. In all, photoelectric sensors and the FPGA controller are adopted in the front-end acquisition device, so the front-end acquisition device is low in cost and simple in structure and can acquire the contours of the different types of objects.

Description

[0001] Technical field [0002] The invention involves the field of video surveillance, especially the front -end collection device of a contour video monitoring system. [0003] Background technique [0004] The current video surveillance system is a comprehensive application of multimedia technology, video compression coding technology, computer network and artificial intelligence technology, and continuously developed in the direction of intelligence.From a functional point of view, video surveillance can be used for security prevention, information acquisition, and command scheduling, which can provide various services such as production process control, security, medical care, and long -range education of large -scale public facilities.From the perspective of the application field, video surveillance has been widely used in all walks of life, such as archives, museums, machine departments, traffic violations and traffic monitoring, residential communities, parking lots, unma...

AI Technical Summary

Problems solved by technology

The land border between our country and neighboring countries is about 22,000 kilometers long, and many of them are remote and uninhabited places. At present, it is quite difficult to implement automatic monitoring in these places. The cost of using the existing video monitoring system is not only difficult to estimate, but also subject to High traffic data limit

At present, there is no monitoring system that realizes the monitoring of the entire border according to the different contour characteristics of different types of objects.
