Embodiment Construction

[0051] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0052] In order to reduce the amount of stored monitoring data and reduce the power consumption of the system while ensuring the quality of the monitoring picture and video data of the target object, the present invention proposes a camera parameter control method in a video monitoring system.

[0053] The parameters involved in the embodiments provided by the present invention and the meanings of the parameters are first introduced below. ...

Abstract

The invention discloses a vidicon parameter control method and device used in a video monitoring system. According to the method, a first vidicon tracking a target object is determined, video encoding parameters of the first vidicon and / or a vidicon which does not track the target object at present are set to make the video quality of the first vidicon higher than the video quality of the vidicon which does not track the target object at present, so that higher quality is produced for monitoring pictures including the target object and picture recording data, and lower quality is produced for monitoring pictures without the target object and picture recording data. Due to the fact that the data memory capacity of monitoring videos lower in quality is smaller, the overall monitoring data memory capacity of the video monitoring system is decreased on the basis that the quality requirement for monitoring pictures and picture recording data of the target object is met, and the power consumption of the video monitoring system is reduced.

Description

technical field [0001] The invention relates to the monitoring field, in particular to a camera parameter control method and device in a video monitoring system. Background technique [0002] Intelligent video surveillance is an application direction that has developed rapidly in the field of computer vision in recent years and has been studied more. It can use computer vision technology to process, analyze and understand the collected video signals, and control the video surveillance system based on this, so that the video surveillance system has better intelligence and robustness. The intelligent video surveillance system mainly involves scientific knowledge in image processing, computer vision, pattern recognition, artificial intelligence, etc. It has a wide range of uses and has broad application prospects in both civilian and military fields. [0003] In the current video surveillance system, cameras all use the same bit rate to store surveillance data. In order to en...
