This paper reflected on the traditional lecture teaching method and proposed an alternative English translation teaching method based on 3D computer vision technology to increase student interest in translation, improve students' translation ability, and compensate for the shortcomings of traditional translation teaching methods. Through experimental research, this paper found that the interactive English translation teaching mode based on 3D computer vision technology was conducive to improving students' translation speed, translation accuracy, comprehensive competence, and the quality of translation teaching. The teacher's composite score was 7.8, and the student's composite score was 8.9. This showed that the interactive English translation teaching mode based on 3D computer vision technology is much more efficient than traditional teaching.
