Document Type and Number:
WIPO Patent Application WO/2020/019131
Kind Code:
A1
Abstract:
A method and apparatus for determining light ray information, and an electronic device. The method comprises: acquiring a target picture, and dividing the target picture into a first preset number of sub-pictures (S101), wherein each of the sub-pictures is composed of a second preset number of pixels; determining the light ray intensity of each of the sub-pictures, and calculating an image moment to determine a light intensity weighting center of the sub-picture (S102); determining, according to the light intensity weighting center of the sub-picture and a geometric center of the sub-picture, a light ray angle of the sub-picture (S103); and respectively calculating the light ray intensity and the light ray angle of the sub-pictures to obtain light ray information corresponding to the target picture (S104). In the method, environmental information, the position and the time of a picture or a video do not need to be pre-acquired, and collection and labeling of a face image or other specific hardware resources are not needed, and the light ray intensity can also be acquired in an area without light. Compared with the prior art, the method is lower in costs and is more convenient and accurate.
