Abstract: Machine vision is the core course of the new engineering subject robot engineering, and there are certain problems with the traditional teaching method of this course. A problem-based teaching method has been proposed through heuristic teaching ideas, which can improve the shortcomings of current curriculum teaching, effectively stimulate students'learning interest, and improve teaching quality and effectiveness. The creation and improvement of two-level problem-based teaching methods have solved the application difficulties of problem-based teaching methods in courses with rapidly updated content, enabling high-quality application of problem-based teaching methods in high iteration new engineering applied courses. The reformed machine vision course can quickly iterate the latest engineering knowledge, enabling students to combine theoretical learning with practical application under the guidance of problems, improve teaching effectiveness, and cultivate students into the talents required by the industry.

Key words: Problem-based teaching, New engineering, Machine vision, Robot engineering, Practical teaching, Two-level problem teaching
