Human body detection method based on depth information

Abstract

The invention relates to human body detection technology, and discloses a human body detection method based on depth information. The human body detection method settles the problems of severe external environment interference and low applicability in human body detection. The human body detection method comprises an image preprocessing step and a human body detection step, wherein the image preprocessing step comprises the steps of extracting image depth information; performing Gaussian image pyramid down-sampling on a depth image; performing gradient histogram processing on the down-sampled image; performing integrogram calculation on a characteristic channel after gradient histogram processing. The human body detection step comprises the steps of finding out a detection area through interframe motion information; performing characteristic judging on a to-be-detected area by means of a classifier based on a discrete AdaBoost algorithm, and detecting whether the human body exists in the area; and merging windows which are judged as the human body through the classifier, and marking the human body area on the image. The human body detection method is suitable for VR.
