The enhancement of details in complex graphic elements is affected by lighting changes, resulting in a decrease in contrast and clarity of graphic details observed by the human eye. Therefore, a method for enhancing the details of complex graphic elements in lighting changes based on laser vision communication is proposed. This method uses a multi-scale retina algorithm with color recovery function to unfold color correction on the collected graphics, and converts the graphics from the RGB color space to the HIS color space that is convenient for human observation through laser vision communication method. Adopting adaptive compensation method and limited contrast adaptive histogram equalization algorithm, the saturation I value and brightness S value of the graph are enhanced, and the enhanced image is converted back to the RGB color space. The experimental results show that this method has good color correction effect and strong stability in enhancing graphic details.
