Abstract

An embodiment of the invention discloses a method and device for adjusting illumination balance. The method comprises the follow steps: carrying out region division on an object region image based on statistical characteristics of a color histogram, determining a classifier corresponding to each region according to correspondence relation between the statistical characteristics and classifiers, and obtaining a color histogram of the object region image according to correspondence relation between the classifiers and histograms; carrying out comparison to judge whether a distribution equilibrium value of the color histogram of the object region image is within the range of a distribution equilibrium value of a color histogram of a sample image; and if not, adjusting light balance parameters of the object region image to enable the distribution equilibrium value of the color histogram of the object region image to be within the range of the distribution equilibrium value of the color histogram of the sample image. The method and device for adjusting illumination balance can solve the technical problem of illumination imbalance in the prior art, thereby improving object recognition rate.

Description

Technical field [0001] The embodiments of the present invention relate to the field of virtual reality technology, and in particular, to a method and device for adjusting light balance. Background technique [0002] Virtual reality technology (VR) is a computer simulation system that can create and experience virtual worlds. It uses a computer to generate a simulation environment. It is an interactive three-dimensional dynamic visual scene and entity behavior system that integrates multi-source information. Simulation immerses the user in the environment. [0003] Virtual reality technology is an important direction of simulation technology. It is a combination of simulation technology and computer graphics man-machine interface technology, multimedia technology sensor technology, network technology and other technologies. It is a challenging cross-technology. [0004] The essentials of virtual reality technology include simulated environment, perception, natural skills, and sensor ...
