Abstract

The invention discloses a light supplementing method and device and a computer readable storage medium. The method comprises the following steps: according to a preset distance adjustment step length,a direction angle adjustment step length, the maximum LED number in a single LED ring and the number of sampling points on a to-be-light-supplemented surface of a light supplementing object, calculating brightness mean values and a brightness variance of all sampling points under each possible LED arrangement mode, and selecting an LED arrangement mode meeting preset brightness and illumination uniformity requirements according to the brightness mean value and the brightness variance, wherein the arrangement mode of the LEDs is a single LED ring or a structure formed by nesting a plurality ofconcentric LED rings; and carrying out light supplement on the light supplement object by utilizing an LED assembly constructed by adopting the selected LED arrangement mode. By adopting the invention, the lighting requirement of an actual application scene can be ensured to be met.

Description

technical field [0001] The present invention relates to computer application technology, in particular to a supplementary light method, device and computer-readable storage medium. Background technique [0002] At present, in order to meet the uniform light source requirements of the digital camera visibility measuring instrument and improve the uniformity of semiconductor light emitting diode (Light Emitting Diode, LED) lighting, a design scheme for the uniformity of LED lighting source is proposed. In this scheme, digital camera sampling is first performed on the module area where a single LED is placed, the characteristics of the luminance distribution are analyzed, and the luminance distribution function of a single LED is fitted. Based on this distribution function, under the fixed power and size, the LED array method with the least unevenness is calculated by using the principle of multi-LED brightness superposition. In the case of fixed power and uniformity, calculat...
