Embodiment Construction

[0035] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0036] Such as Figure 1-3 Shown, in the first embodiment of the present invention, provide a kind of network camera 200 decoding method based on OpenCV, described method comprises:

[0037] Step S1, in response to the first obstacle detected by the light curtain module 100, send an opening instruction to the network camera 200 corresponding to the light curtain module 100; wherein, the light curtain module 100 includes multiple pairs of parallel arrays The infrared pair tubes are arranged, and the light curtain surface formed by each pair of the infrared pair tubes is perpendicular to the ground; the light curtain module 100 is used to detect pedestrians passing by and the height of pedestrians; the infrared pair tubes are divided into the lower section according to the height The pair of tubes 130, the middle section of the tube 120 and the upper section o...

Abstract

The invention discloses an OpenCV-based network camera decoding method, which relates to the field of security, including: firstly, in response to the first obstacle detected by the light curtain module, an opening instruction is sent to the network camera corresponding to the light curtain module, and the cloud The platform collects the first image of each frame of the network camera sequentially and in real time based on OpenCV; then, recognizes the first fixed point above the head of the pedestrian in the first image, controls the shooting direction of the network camera to point to the first fixed point, and collects in real time The shooting angle of the network camera; the shooting angle is the angle between the network camera and the vertical direction; then, collect the first real-time shooting angle and the second real-time shooting angle to obtain the height of the pedestrian, and solve the abdominal thickness of the pedestrian; finally, save Each frame of the first image constitutes the first video, and the pedestrian's height, abdomen thickness and passing time stamp are marked. The invention effectively analyzes the video shot by the network camera through OpenCV, so as to obtain the required data through image processing.

Description

technical field [0001] The invention relates to the field of intelligent security, in particular to an OpenCV-based network camera decoding method. Background technique [0002] OpenCV is a cross-platform computer vision library released under the BSD license (open source), which can run on Linux, Windows, Android and Mac OS operating systems. It is lightweight and efficient-consisting of a series of C functions and a small number of C++ classes, while providing interfaces for languages ​​such as Python, Ruby, and MATLAB, and implementing many general-purpose algorithms in image processing and computer vision. [0003] OpenCV is written in C++ language, and its main interface is also C++ language, but still retains a large number of C language interfaces. The library also has extensive interfaces to Python, Java and MATLAB / OCTAVE (version 2.5). The API interface functions of these languages ​​can be obtained through online documentation. Now also provides support for C#, ...
