A method and system for generating CAD instructions based on eye movement signals

Abstract

The invention discloses a method for generating CAD instructions based on eye movement signals. The CAD instruction generation method comprises: collecting raw data of eye movement signals in real time through a camera on a computer; determining a time series according to the raw data; the time series corresponding to the eye movement signals; adopting a Kalman filter method to The time series is filtered to determine the filtered time series; the SVM classification model is trained according to the time series; the filtered time series is input to the SVM classification model, and the signal feature category is output; according to the signal The feature category generates CAD instructions and draws CAD graphics. The CAD instruction generation method and system provided by the present invention can accurately identify the user's design intention and generate correct CAD instructions to drive CAD software to draw corresponding graphics.

Description

technical field [0001] The invention relates to the field of design intention recognition, in particular to a method and system for generating CAD instructions based on eye movement signals. Background technique [0002] The emergence of computer-aided design (Computer-Aided Design, CAD) technology has greatly shortened the product development cycle, improved product design quality, and provided convenience for users; with the rise of artificial intelligence technology, intelligent human-computer interaction technology There are broad application prospects. [0003] The existing mainstream technology relies on the mouse and keyboard for human-computer interaction, and the operation is cumbersome. On the one hand, because the design rules must ensure versatility and logic, the operation process is rigid and complicated, and the interaction process does not actively satisfy human needs. Requirements, only thinking about realizing the design function. On the other hand, the r...
