Problems solved by technology

[0002] In order to better obtain the information in the environment, it is usually possible to recognize the information in the environment based on the images captured by the camera, but the images captured by the camera obtained by using the existing image processing technology cannot be applied to all environments, and the light is variable. It is difficult for the camera to output high-quality images according to different ambient lights. There will always be good image quality when the light is good, and poor image quality when the light is poor, which leads to poor environmental information perception.

Embodiment Construction

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0039] The technical terms involved in this application document are briefly introduced below.

[0040] Visible light is an electromagnetic wave that the human eye can perceive. The visible spectrum has no precise range. The wavelength of electromagnetic waves that can be perceived by ordinary people's eyes is between 400 and 760nm (nanometers), but some people can perceive the wavelength at about 380 to 780nm. between electromagnetic waves.

[0041] Near-infrared light refers to e...

Abstract

Embodiments of the present application provide an image processing method and system. The image processing system includes: the image sensor generates and outputs a first image signal through exposure, the first image signal is an image signal generated according to a first preset exposure, and the first preset exposure is any one of multiple exposures The supplementary light device is used to perform near-infrared supplementary light in a stroboscopic manner, specifically: the supplementary light device performs near-infrared supplementary light in the exposure time period of the first preset exposure; the image processor is used for receiving the first image signal output by the image sensor, and generating a first target image according to the first image signal; an intelligent analysis device, configured to determine the first target image as an image to be analyzed, and perform intelligent analysis on the image to be analyzed , to obtain the intelligent analysis result corresponding to the image to be analyzed. Therefore, the solution can improve the quality of the image to be analyzed for output or intelligent analysis.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to an image processing method and system. Background technique [0002] In order to better obtain the information in the environment, it is usually possible to recognize the information in the environment based on the images captured by the camera, but the images captured by the camera obtained by using the existing image processing technology cannot be applied to all environments, and the light is variable. It is difficult for the camera to output high-quality images according to different ambient lights. There will always be good image quality when the light is good, and poor image quality when the light is poor, which leads to poor information perception of the environment. Contents of the invention [0003] The purpose of the embodiments of the present application is to provide an image processing method and system to improve the quality of an image to be an...
