The invention provides a method and a device for detecting a specific target area in a color-free scene video. According to the method and the device, a video scene region type descriptor is constructed by comprehensively utilizing different time-space information such as brightness, texture, outline and dynamics in the color-free video, therefore, the specific target area is detected and determined. Based on the video scene area type descriptor, a feature extraction and calculation method on each information channel is simple and efficient, the real-time performance is good, the video samplelearning efficiency is high, and real-time online training can be realized; furthermore, the method and the device calculate the type value of each channel of the video scene area type descriptor; inaddition, a parallel computing method is introduced, and the overall operation efficiency of the method is remarkably improved, so that the problems of low operation efficiency, poor real-time performance and even failure when an existing method is implemented for detecting a specific target area in a color-free video are solved.
Description
technical field [0001] The present invention relates to the technical field of video processing, in particular to a method and device for detecting a specific target area in a colorless scene video. Background technique [0002] With the vigorous development of technologies such as visual mobile robots, unmanned driving, and drones, the importance of vision-based scene analysis technology has become increasingly prominent. The detection and identification of specific target areas is a key technology in vision-based scene analysis, because the detection and identification results of specific target areas (such as common obstacles) will directly affect the quality of mobile robots, unmanned driving, and unmanned vehicles. The operation mode and operation safety of man-machine and other equipment. [0003] Since unmanned vehicles, unmanned aerial vehicles and other equipment usually operate at relatively high speeds, the analysis and processing efficiency of real-time video da...
