Abstract: The research is combined with the latest trend in science and technology: structural light-based machine vision technology. The experimental teaching design of "three layers and four structures" based on the experimental teaching platform of machine vision was carried out: learning verification experiments, research verification experiments, exploration innovation experiments and engineering innovation experiments. To realize targeted and task-driven experimental education for students with different learning levels and interest directions, so as to reflect the training goal of diversified talents, students are guided to start from software simulation, to achieving the overall integrated structure design in comprehensive experimental learning. Students could perceive the charm of creative learning and the transformation of undergraduate teaching from "teaching well" to "learning well" is actively promoted.

Key words: cultivation target, machine vision, three layers and four structures, experimental design
