Problems solved by technology

The main defect of this method is that it relies more on the detection of pedestrians. When there are many pedestrians forming occlusions, the human frame obtained by the detection model will be missing (not including the feet) or the detected human frame will be inaccurate, which will eventually affect the positioning accuracy of pedestrians.
[0003] In view of the problems existing in the above-mentioned pedestrian positioning methods, no effective solution has been proposed

Abstract

The invention provides a pedestrian positioning method, a device, a processing device and a storage medium thereof, which relate to the positioning technical field. The method comprises the followingsteps: respectively collecting a head image of a target object by at least two image acquisition devices; inputting a head image into a pre-trained head recognition network; the head features in the image being recognized by the head recognition network, and the head coordinates corresponding to the head features being obtained; matching head features corresponding to at least two image acquisition devices; if the matching is successful, the pedestrian three-dimensional reconstruction being performed according to the head coordinates and the coordinates of at least two image acquisition devices. 3-D reconstruction is carried out by using a head image in the embodiment of the present invention, compared with the foot, the head is not easily occluded, the data collection is easy, and the characteristic dimension is smaller, the training convergence is faster, the false detection rate and the missed detection rate are lower, the false positioning caused by the occlusion of the foot can bereduced, the positioning dimension is higher, the robustness is better, and the positioning effect of pedestrians is improved.

Description

technical field [0001] The present invention relates to the technical field of positioning, in particular to a pedestrian positioning method, device, processing equipment and storage medium thereof. Background technique [0002] The existing pedestrian positioning methods are generally based on the calibrated camera to locate pedestrians through the ground. The specific algorithm process is as follows: firstly, the person frame is identified, and the bottom of the person frame is used as the foot of the pedestrian, and the two-dimensional positioning of the pedestrian is carried out in combination with the calibrated ground. The main defect of this method is that it relies more on the detection of pedestrians. When there are many pedestrians occluding, the person frame obtained by the detection model will be missing (not including the feet) or the detected person frame will be inaccurate, which will eventually affect the positioning accuracy of pedestrians. [0003] For the...
