Summary:The invention relates to the technical field of virtual reality technology, in particular to a three-dimensional gesture recognition algorithm for a virtual reality learning classroom, which can achieve a better effect under the condition that a large number of data samples and more gesture types are not needed, is suitable for real-time gesture recognition and meets VR three-dimensional gesture interaction in different environments. In a data source, a three-dimensional gesture is randomly acquired by a camera, then a three-dimensional gesture sample is initialized and matrix-formed, then according to a gesture image noise reduction preprocessing algorithm, features with high importance are selected, original data samples are optimized, features with low importance are removed, an optimal decision tree is established by adopting an XGBoost algorithm, and a three-dimensional gesture image is obtained. The method comprises the following steps of: establishing an optimal decision tree by adopting an XGBoost alg
