Problems solved by technology

[0002] With the rapid development of machine vision technology, the use of machine vision to replace human eyes has become the trend of intelligent development in all walks of life. Machine vision mainly relies on the real-time images transmitted by the camera during the monitoring process for further image recognition. However, in the process of real-time monitoring of the camera, the camera may be blocked or unnaturally moved, which affects the monitoring quality of the camera and causes difficulties for the subsequent image recognition process

Abstract

The invention relates to a method and a device for detecting sheltered movement of a camera. The method comprises the following steps: extracting a front frame image and a rear frame image of a video collected by a camera, and graying the images to obtain gray images; using a frame difference method to obtain a difference image of the gray level images of the front frame image and the rear frame image; binarizing the difference image to obtain a binary image; and judging whether the camera is shielded or moved or not according to a comparison result of the number of the pixel points with the gray value of 255 in the binary image and a judgment threshold value. According to the scheme provided by the invention, whether the camera is shielded or moved can be accurately judged by processing the video image collected by the camera, so that background operation and maintenance personnel can take measures in time, the monitoring quality of the camera is ensured, and the subsequent image recognition processing process is facilitated.

Description

technical field [0001] The invention relates to the fields of image recognition and safety supervision, and in particular to a method and device for detecting a camera being blocked and moving. Background technique [0002] With the rapid development of machine vision technology, the use of machine vision to replace human eyes has become the trend of intelligent development in all walks of life. Machine vision mainly relies on the real-time images transmitted by the camera during the monitoring process for further image recognition. However, in the process of real-time monitoring of the camera, the camera may be blocked or unnaturally moved, which affects the monitoring quality of the camera and causes difficulties for the subsequent image recognition process. Contents of the invention [0003] In order to overcome the problems existing in the related art, the present invention provides a method and device for detecting that the camera is blocked and moved. [0004] Accor...
