Abstract

The invention provides a gesture pre-judging method and system. The method includes: detecting the current gesture initiating coordinates of a gesture guider, and sequentially recording the sequence of the current motion trajectory coordinates, starting from the initiating coordinates, of the gesture guider; extracting the current motion trajectory feature vectors of the gesture guider according to the sequence at every other first preset time interval; using a pre-trained gesture recognition model to perform mode matching on the extracted current motion trajectory feature vectors, and outputting matched complete gesture identification; wherein the pre-trained gesture recognition model is acquired by training pre-collected gesture feature vector sample sets, and the pre-collected gesture feature vector sample sets comprise a plurality of partial motion trajectory feature vectors formed by cutting off continuous features from the beginning of the complete motion trajectory feature vectors of complete gestures according to preset proportions. By the gesture pre-judging method and system, real-time gesture recognition can be achieved.

Description

technical field [0001] The invention relates to the technical field of pattern recognition, in particular to a gesture prediction method and system. Background technique [0002] With the wide application of computers, the traditional human-computer interaction method of manipulating physical buttons is not natural and convenient, and using human hands as a means of human-computer interaction is more natural, direct, and richer than other biological features, and can greatly improve the human-computer interaction. Enhance user experience. The initial gesture recognition mainly uses external devices to directly detect the angle and spatial position of the joints of the hand and arm, such as typical data gloves. Although these external devices improve the accuracy and stability of gesture recognition, they do not conform to gesture recognition. natural expression. So vision-based gesture recognition came into being. The vision-based gesture interaction method is a non-conta...
