Document Type and Number:
WIPO Patent Application WO/2021/160001
Kind Code:
A1
Abstract:
The present application provides an image acquisition method and device. The image acquisition method of the present application comprises: acquiring first original image data, the first original image data being collected by an image sensor on the basis of an initial visible light exposure parameter and initial light intensity of an infrared light supplement lamp; acquiring brightness of a visible light image according to the first original image data; adjusting the visible light exposure parameter according to a first difference, the first difference being a difference between the brightness of the visible light image and brightness of a preset target visible light image; acquiring brightness of an infrared image according to the first original image data; adjusting the light intensity of the infrared light supplement lamp according to a second difference, the second difference being a difference between the brightness of the infrared image and brightness of a preset target infrared image; acquiring second original image data, the second original image data being collected by the image sensor on the basis of the adjusted visible light exposure parameter and the adjusted light intensity of the infrared light supplement lamp; and performing fusion to obtain a target image according to the second original image data. The present application can improve the adjustment efficiency, thereby obtaining a target image having a better signal-to-noise ratio and better detail performance.
