Monitoring equipment water mist and frost treatment method and device, equipment and medium

Abstract

The invention relates to a water mist and frost treatment method and device for monitoring equipment, the equipment and a medium. The method comprises the following steps: acquiring a current frame image acquired by monitoring equipment; obtaining a to-be-detected area in the current frame image, wherein the to-be-detected area is at least one definition statistical area divided in advance; counting the current definition of the to-be-detected area, and judging whether the counted current definition meets a corresponding definition condition or not; and carrying out water mist and frost removal operation on the to-be-detected area of which the current definition does not meet the corresponding definition condition. By adopting the method, other hardware does not need to be additionally mounted.

Description

technical field [0001] The present application relates to the technical field of monitoring equipment cleaning, in particular to a monitoring equipment water mist frost treatment method, device, equipment and medium. Background technique [0002] A smart city is to use information and communication technology to sense, analyze, and integrate key information of the core system of urban operation, so as to respond intelligently to various needs including people's livelihood, environmental protection, public safety, urban services, and industrial and commercial activities. Among them, the monitoring camera is a kind of smart city equipment. The monitoring camera is a semiconductor imaging device, which has the advantages of high sensitivity, anti-glare, small distortion, small size, long life, and anti-vibration.

AI Technical Summary

Problems solved by technology

[0003] When the monitoring camera is used in a humid environment such as rainy days, water mist will be formed on the inner wall of the protective cover on the monitoring camera, and the water mist will affect the shooting line of sight of the monitoring camera.

Traditionally, in order to remove the water mist of the surveillance camera, it is possible to mount a temperature and humidity detection module or mount an external MCU (Microcontroller Unit, Micro Control Unit) to determine whether the image is foggy. Although these methods can achieve automatic detection And activate the effect of removing water mist, but the mounting temperature detection module needs to reserve more hardware space, the assembly is more complicated, and the cost will be higher

For the method of externally mounting the MCU, see figure 1 , because the MCU cannot directly obtain the image information and needs to provide it through the ISP (Image Signal Processing, Image Signal Processing), which will cause the ISP to provide additional pins and the ISP to consume additional performance to send the image information to the MCU for interpretation

At the same time, there will also be problems such as the above-mentioned need to reserve more hardware space, more complicated assembly, and higher cost.
