Embodiment 1
[0095] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0096] A sitting posture recognition method combining projection information and multiple-input multiple-output neural network (MIMO-CNN), the flow chart is as follows figure 1 shown. Include the following steps:
[0097] Step 1, the specific implementation process of image acquisition is:
[0098] A1, use the depth camera to obtain the depth image, such as figure 2 ;
[0099] A2, use the random decision forest classification algorithm of the official SDK of the depth camera to finally divide the human body into 32 parts, and finally get the human body foreground contour we need, such as image 3 ;
[0100] Step 2, the process of image preprocessing is:
[0101] B1. Perform histogram avera...
