Video jitter quantization method and video jitter quantization device

Abstract

The invention discloses a video jitter quantization method and a video jitter quantization device. The video jitter quantization method comprises the steps of receiving image data, and obtaining a Canny edge image of luma and chroma (YUV) component of the obtained image data; and detecting motion range between two frames according to the Canny edge image, and obtaining video jitter data. According to the video jitter quantization method and the video jitter quantization device, quantization is conducted on video jitter according to image edge information and frame difference motion information, and alarm is conducted on abnormal phenomena such as the video jitter according to a series of externally-set threshold value. The video jitter quantization method and the video jitter quantization device are simple and easy to operate, fast in calculation speed and reasonable in result.

Description

technical field [0001] The present invention relates to the technical field of video monitoring, in particular to the technical field of video image processing, and in particular to a video shake quantization method and device. Background technique [0002] With the rapid development of the social economy, the security monitoring market has expanded rapidly, and the number of video surveillance cameras and DVRs (Digital Video Recorders, Digital Video Recorders) has shown geometric growth. How to effectively use and manage these massive data and videos is a key issue for the security monitoring industry. An important issue that must be addressed. [0003] In the existing security monitoring technology field, some surveillance cameras must be installed in a vibrating environment, such as being fixed outside a high building, on a bridge, tunnel or pole, or on a machine (such as a car, an airplane, a ship, etc.) , windy coast, heating and ventilation equipment, air conditioners...

AI Technical Summary

Problems solved by technology

[0003] In the existing security monitoring technology field, some surveillance cameras must be installed in a vibrating environment, such as being fixed outside a high building, on a bridge, tunnel or pole, or on a machine (such as a car, an airplane, a ship, etc.) , windy coast, heating and ventilation equipment, air conditioners, PTZ heads, etc., there must be mechanical vibrations, and these mechanical vibrations are often difficult to eliminate. Mechanical vibrations will cause video images to shake, especially when using high-magnification lenses. Under normal circumstances, a slight mechanical vibration will cause severe shaking of the image, which will seriously affect the observation and monitoring of the video

[0004] At the same time, since the surveillance camera is installed in a vibrating environment, it is more likely to loosen or fall off the fixation, which not only causes damage to the camera, but also fails to monitor the predetermined area
