Embodiment Construction

[0057] figure 1 is a schematic flowchart of a method for adjusting the angle of an illumination system based on an image brightness gradient according to an embodiment of the present application. This embodiment provides a method for adjusting the angle of an illumination system based on an image brightness gradient, wherein there is one illumination module, and the method may generally include the following steps:

[0058] S100. Acquire a target image under the current lighting condition, and store it as an image to be tested. More specifically, the target image is acquired by the camera.

[0059] S200, input the set initial parameters through the CPU processor, wherein the initial parameters include the termination condition threshold R, in this embodiment, R=10, of course, in other embodiments, R can also be 20, 30, 40 and other grayscale values.

[0060] Furthermore, in practical applications, in order to improve efficiency and save system CPU resources, only a limited ...

Abstract

The application discloses a method and system for adjusting an illumination angle based on an image brightness gradient, and relates to digital products. The method and system obtain the image to be tested, convert it into a grayscale image, calculate the gradient direction through an algorithm, derive the angle corresponding to the gradient amplitude, and adjust the direction of illumination through the gradient direction, so that the light can be adjusted according to the brightness gradient direction of the image. Illumination, adjust the illumination angle through the angle, enhance the illumination in the central area, so as to give sufficient illumination conditions. Using the method and system of the present application can automatically adjust the illumination angle and illumination direction when the equipment is stationary or in motion, which not only saves labor and time costs, but also reduces the wear and maintenance times of the digital camera.

Description

technical field [0001] The present application relates to digital products, in particular to a method and system for adjusting an illumination angle based on an image brightness gradient. Background technique [0002] Products with cameras include digital cameras, digital video cameras, underwater drones, drones and other products. Taking the underwater drone as an example, since the layout of the camera and lights in the existing digital cameras are fixed, when shooting the target object in the dark field environment, at different relative distances and different relative angles In some cases, the central area of ​​the presented picture has different degrees of insufficient illumination. [0003] In order to solve the above phenomenon of insufficient illumination, it is often necessary to repeatedly adjust the layout position and angle of the digital camera to meet the special illumination requirements and effects of shooting target objects in a dark field environment. Ho...
