The invention relates to the technical field of computer vision processing, and discloses a door state detection method and device, and a car passenger flow statistics method and equipment. In the door state detection method, the background difference method is first used to extract the moving foreground image corresponding to the single frame image in the door monitoring video, and then the moving foreground image is sequentially subjected to edge contour detection processing and straight line number detection processing. The number of corresponding straight lines is obtained, and finally the comparison result between the number of straight lines and the preset threshold is used as the basis for determining whether the door state is the state of door opening motion during collection, and the detection result of the door state is obtained, which not only enables the final detection result to be accurate when the door is opened. Eliminate the interference caused by other stationary objects with straight lines in the field of view, effectively improve the accuracy of the door state detection results, and apply to all video surveillance scenarios, and can reduce equipment complexity and hardware costs, which is conducive to assisting car passengers Traffic Statistics.
Description
technical field [0001] The invention belongs to the technical field of computer vision processing, and in particular relates to a door state detection method and device, and a car passenger flow statistics method and equipment. Background technique [0002] In the era of rapid economic and technological development, high-rise buildings are becoming more and more popular, and the number of elevators has also increased dramatically. Given the complexity of the structure and the high density of residents, public safety is a challenge for this type of building. With the rapid development of artificial intelligence and the increasing demand for intelligent services in the society, as an important transportation carrier and key channel for public places in residential buildings, elevators have an increasing demand for intelligence, and among them, one of the most important aspects It is the intelligent video surveillance in the elevator. [0003] Pedestrians are one of the impor...
