摘要： A person counting method and a person counting system are provided. The method includes extracting a group of person images to obtain a first image set; dividing the first image set into first and second subsets based on whether a related image exists in a second image set, and reusing a person ID of the related image; estimating posture patterns of images in the first subset, and storing the images in the first subset into an image library based on person IDs and the posture patterns; and selecting a target image whose similarity to an image in the second subset is highest from the image library, reusing a person ID of the target image when the similarity is greater than a threshold, and assigning a new person ID and incrementing a person counter by 1 when the similarity is not greater than the threshold.

In the method, a plurality of sets of panoramic images respectively corresponding to two respective adjacent subspaces are obtained. Each set of the panoramic images includes two first panoramic images, and a second panoramic image photographed at a connection opening. Orientations of the connection openings are determined based on positions of the connection openings, and orientations of a camera. Relative positions of the two adjacent subspaces are determined based on correspondence relations between the two first panoramic images and parts of the respective second panoramic images. The connection relation of the subspaces is determined based on the connection relation determined based on the same subspace, the orientations of the connection openings, and the relative positions of the two adjacent subspaces.
