However, since the algorithmic complexity of the forward algorithm is O(n 2T ), its calculation speed is low, and the calculation time is longer, which is not conducive to the operation of the computer
In addition, the existing HMM model is a specific motion trajectory model with fewer types, so it is difficult to cover other more complex motion trajectories, resulting in a low recognition rate of the algorithm and few types of motion trajectories that can be recognized

The embodiment of the invention provides a human body track recognition method and device. The method includes the steps that the human motion track is acquired; the motion track is decomposed into a plurality of characteristics, and a test sample is generated on the basis of the multiple characteristics; the similarities between the test sample and a plurality of sample sets is calculated, and each sample set represents one motion track; the motion track represented by the sample set with the largest similarity to the test sample is output. Through the human body track recognition method and device, the operating speed and the recognition rate can be effectively increased.
Description
technical field [0001] The invention relates to the field of artificial intelligence, in particular to a method and a device for identifying a human motion track. Background technique [0002] Human-computer interaction is a study of the interactive relationship between the system and the user. In the transformation of science and technology, in order to make human-computer interaction more anthropomorphic and natural, researchers have been devoting themselves to designing a more perfect human-computer interaction method that can be accepted by the public, so as to improve the communication between users and computers. , while improving interaction efficiency and facilitating users' lives. [0003] In human-computer interaction, the movement posture of the human body, such as gestures, is the most widely used communication method in users' daily life. Due to the diversity and ambiguity of gestures, it is still in the research field to allow computers to fully explain the ge...
