Problems solved by technology

[0007] Although human behavior recognition based on deep learning has made some progress, however, human behavior recognition based on 2D video still faces many challenges, including the difference of inter-class and intra-class data and scene changes. The person itself is a complex non-rigid object. Human action recognition is affected by individual differences in human appearance, posture, movement, clothing, perspective changes and camera moveme

Embodiment Construction

[0042] The invention will be described in further detail below in conjunction with the accompanying drawings.

[0043] Such as figure 1 As shown, the present invention provides a computer vision-based express delivery violence sorting recognition method, the method includes the following steps:

[0044] Step 1: Depth camera-based pose estimation: Pixels in the depth image record the calibrated depth of the scene, not the value of scene intensity or color. Depth cameras operate at lower light levels than traditional intensity sensors and are affected by color and texture variations Small advantage, and solves the problem of ambiguous outlines of poses. Depth image technology has developed greatly in the past few years. With the release of Kinect, it has finally become a low-cost product. The schematic diagram of the depth camera Kinect is as follows figure 2 shown. The present invention adopts the literature "Shotton J, Sharp T, Kipman A, et al. Real-time humanpose recognit...

Abstract

The present invention discloses a computer vision-based express parcel violent sorting identification method. The method comprises the following steps of: a depth camera-based pose estimation: a human pose estimation problem is converted into a problem of classifying depth image pixels captured by a depth camera, and human body pose estimation is realized by using a random forest method; human body three-dimensional pose relative spatial-temporal feature extraction: relative spatial-temporal positions of geometric elements of points, lines and surfaces formed by joints in three-dimensional poses and the measures of the change of the relative spatial-temporal positions are extracted and are adopted as the feature representations of the poses; and recurrent neural network-based violent sorting identification: modeling training is performed on the pose spatial-temporal relative features which are continuous in time and are extracted from the human body three-dimensional poses through a long and short memory model (LSTM), so that the identification of express parcel violent sorting behaviors can be realized.

Description

technical field [0001] The invention belongs to the technical field of computer vision and pattern recognition, and relates to a computer vision-based express violent sorting and recognition method. Background technique [0002] With the increasing demand for express delivery services in new service industries such as e-commerce and online shopping, my country's express delivery industry has shown a trend of rapid development. Express delivery has become a livelihood service that connects hundreds of millions of merchants and the general public. It plays an increasingly important role in promoting consumption upgrading. Compared with previous years, the service quality and sorting efficiency of my country's express delivery industry are constantly improving, but industry problems such as "violent sorting" are still emerging one after another. Open Bing or Baidu search, and there are hundreds of thousands of web pages related to violent sorting. The chaos of "violent sorting"...
