Abstract

An embodiment of the invention provides a method and device used for pedestrian detection and gesture estimation. The method includes acquiring a to-be-processed image; inputting the to-be-processed image into a first full convolution network so as to acquire articulation point feature maps relevant to each type of pedestrian articulation points in a first preset number of types of pedestrian articulation points and pedestrian feature maps relevant to each pedestrian in at least one part of pedestrians in a to-be-processed image respectively; forming a combined feature map through combining all the acquired pedestal feature maps and the all the articulation point feature maps together so as to acquire the pedestrian position and the articulation point position of each pedestrian among theat least one part of the pedestrians. According to the embodiment, intermediate results of pedestrian detection can assist pedestrian gesture estimation and intermediate results of pedestrian gestureestimation can also be used for pedestrian detection, so that the accuracy of pedestrian detection and pedestrian gesture estimation can be improved.

Description

technical field [0001] The present invention relates to the field of computers, and more particularly to a method and device for pedestrian detection and attitude estimation. Background technique [0002] In the field of surveillance, pedestrian detection (ie, pedestrian localization) and pedestrian pose estimation play a very important role. However, current algorithms address both problems separately. For example, pedestrian detection is first performed on video frames, and the position of each pedestrian (usually represented by a pedestrian frame bounding-box) is obtained according to the intermediate results of pedestrian detection. Then, by analyzing the content inside the pedestrian frame, the joint point (skeleton) data of each pedestrian, that is, the pose (pose) data is obtained. Since the two problems are split, the intermediate results of pedestrian detection cannot be used to assist the estimation of pedestrian pose. Likewise, the pose information of pedestria...
