Example Embodiment

[0057] figure 1 It 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, in which there is one illumination module, and the method generally includes the following steps:

[0058] S100: Acquire a target image under current light illumination conditions and store it as a test image. More specifically, the target image is acquired by the camera.

[0059] S200: Input the set initial parameters through the CPU processor, where the initial parameters include the termination condition threshold R. In this embodiment, R=10. Of course, in other embodiments, R may also be 20, 30, 40 and other gray values.

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

Abstract

The application discloses an illumination angle adjustment method and system based on an image brightness gradient, relating to a digital product. The method and system include the following steps: acquiring an image to be measured, converting the image to be measured into a grayscale image, calculating a gradient direction by using an algorithm, deriving an angle corresponding to a gradient amplitude, adjusting an illumination direction through the gradient direction to ensure that the light can be irradiated according to the brightness gradient direction of the image, adjusting an illumination angle based on the angle, and enhancing the illumination of a central area to further provide sufficient illumination conditions. By adopting the method and system disclosed by the application, theillumination angle and the illumination direction can be automatically adjusted when equipment is in a stationary state or in a movement state, so that the labor cost and time cost can be saved, andthe wear and maintenance times of a digital camera can also be reduced.

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...
