Human figure identification method

Abstract

The invention relates to a human figure identification method, comprising the following steps of: scanning a to-be-scanned target in a scene to acquire scanning data; acquiring height and distance of each scanning point in the scanning data; extracting the scanning points of which the heights are more than a height threshold; building a conical body which comprises the scanning points of which the heights are more than the height threshold; and if the height and the radius of the conical body are consistent with a preset height and a preset radius, judging the scanning target in the scene to be the human figure. In the human figure identification method, the height and distance of each scanning point can be acquired by acquiring the scanning data of the scanning target in the scene, the scanning points of which the heights are more than the height threshold are used for building the conical body, and the height and the radius of the conical body are compared with the preset height andthe preset radius, thus a method for accurately judging whether the scanning target in the scene is the human figure or not is realized.

Description

technical field [0001] The invention relates to a human figure recognition method, in particular to a method for detecting passenger flow human figures by using three-dimensional laser scanning. Background technique [0002] With the prosperity and development of the social economy and the substantial improvement of people's material living standards, social and public activities such as travel, tourism, parties, shopping, and entertainment have become indispensable in people's daily lives. Various public places, commercial streets, tourist attractions and other densely populated places are often full of bustling crowds. Taking the subway as an example, the Beijing subway has more than 400 entrances and exits, 16 transfer stations, and 4 million passengers a day. Crowd gathering has brought huge potential safety hazards to these places, and also put forward higher management requirements for management departments at all levels. According to relevant regulations, when the ...

Problems solved by technology

However, the shape of the target cannot be accurately scanned by two-dimensional laser or infrared rays, and only the rough shape of the scanned target can be obtained. Therefore, other scanned targets are often mistakenly identified as human figures. Therefore, two-dimensional laser or infrared rays are used to count passenger flow accuracy. Not high, unable to obtain accurate passenger flow information
