Power adjustment method, device, computer equipment and storage medium for fill light

Abstract

The present application relates to a power adjustment method, device, computer equipment and storage medium for a fill light. The supplementary light is used for supplementary light in the process of photographing image information in rainy days, and the method includes: calibrating the power of the supplementary light to obtain the influence of the power of the supplementary light on the rainy day image information proportional coefficient; obtain the background pixel information background image information and raindrop pixel information raindrop image information in the rainy image information; use the background pixel information background image information and the raindrop pixel information raindrop image information to obtain the raindrop reflective effect on the The evaluation index of image information in rainy days; according to the evaluation index and the influence proportional coefficient, the power of the fill light is adjusted. It realizes the automatic adjustment of the power of the supplementary light to reduce the influence of raindrops on the image information in rainy days, and solves the problem that the supplementary light affects the appearance design and control of the camera in the prior art.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular, to a power adjustment method, device, computer equipment and storage medium for a fill light. Background technique [0002] Raindrop mapping on an image or video will cause sharp fluctuations in pixel intensity, which degrades the performance of outdoor vision systems. To make the vision system work robustly in rainy days, we must try to remove the degradation effect of raindrops on images. [0003] In the prior art, the distance between the fill light and the lens is increased to reduce the reflection of close-range raindrops, thereby suppressing the degradation effect of raindrops on the image. Lack of flexibility, inconvenient control of cameras and fill lights. [0004] However, based on the problem that the supplementary light in the prior art affects the appearance design and inconvenience of control of the camera, no solution has been proposed. SUMMARY OF ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the distance between the fill light and the lens is increased to reduce the reflection of raindrops at close range, thereby suppressing the degradation effect of raindrops on the image. However, the built-in fill light has a great impact on the camera's exterior design, and the external fill light Lack of flexibility, camera and fill light control is inconvenient

[0004] However, based on the problem that the supplementary light in the prior art affects the camera's exterior design and inconvenient control, no solution has been proposed yet.
