Gesture interaction geometric modeling method, system, device and equipment for cloud native CAD software

The invention discloses a cloud native CAD software gesture interaction geometric modeling method, system, device and equipment, and the method comprises the steps: firstly collecting a gesture for simulating a mouse to control cloud native CAD software, and recognizing corresponding geometric model data; preprocessing the gesture data; inputting the preprocessed gesture data into a hidden Markov model (HMM), and recognizing a gesture sequence corresponding to the three-dimensional modeling operation; and finally, based on the recognized gesture sequence, executing corresponding geometric modeling operation in cloud native CAD software. According to the method, the gesture recognition technology and the CAD technology are combined, the learning threshold of geometric modeling and product design is effectively reduced, and the man-machine interaction of three-dimensional modeling is improved by utilizing the vertical virtual light curtain of the Leap Motion sensor; according to the method, the gesture data siz
