Abstract

The invention discloses a white balance processing method and device, a movable platform and a camera, and the method comprises the steps: firstly detecting gray points in an image, then building a statistical histogram through all gray points, finally estimating the illumination through the histogram, and carrying out the white balance processing. Only gray points useful for illumination estimation are adopted during histogram construction, and color points which may interfere with illumination estimation are removed, so that the accuracy of illumination estimation is improved; meanwhile, since the gray of the images acquired by different image acquisition devices is common, the generalization ability is improved.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, in particular, to a white balance processing method and device, a movable platform, and a camera. Background technique [0002] The human visual system has the characteristic of color constancy, that is, the human eye can adapt to different lighting conditions, and restore the scene color under different lighting conditions to the scene color under white light irradiation. However, an image acquisition device (for example, a camera) often does not have color constancy capability when taking pictures. Therefore, it is necessary to perform white balance processing on the image collected by the image acquisition device, so as to detect the illumination of the shooting scene, eliminate the influence of the illumination, and return the picture to the color illuminated by white light. [0003] Traditional white balance processing methods can be roughly divided into two categories: th...
