基于逆向反求的《机器 3D 测绘》 实践训练方法研究

开展《机器 3D 测绘》实践训练有助于巩固零部件测量和绘制技能，提高学生分析 与设计表达能力，增强学生工程应用能力。引入逆向工程测量技术，提出测绘实践训练目标、实 施流程和具体要求。明确测绘对象选取原则，选定测量工具，制定零件三维特征建模和逆向重构 方法。提出组长负责制的训练计划，组间互评、小组自评与教师评定结合的综合评价方法，制定 详细评分标准和策略。应用实践表明，该训练方法提升了学生综合运用现代设计技术方法的能力， 增强了工程素质，提高了就业能力。

Practice Training Method Study of Machine 3D Surveying and Mapping Based on Reverse Engineering

Carrying out machine 3D surveying and mapping practice training can help consolidate parts measuring and drawing skills, improve students’ ability to analyze and design expression, and enhance students’ ability of engineering practice. By introducing reverse engineering measurement technology, the objective of surveying and mapping practice, implementation process and the specific requirements were put forward. The principle of selecting surveying and mapping objects was put forward, measuring tools were selected, and 3D feature modeling and reverse reconstruction method were determined. The team leader’s responsibility system was planned. The comprehensive evaluation strategy of the group evaluation, the group self-assessment and the teacher’s evaluation was established. The detailed scoring criteria for group evaluation and teacher evaluation were formulated. The application of the practice training method shows that it is an effective way to enhance the students’ ability of utilizing modern design techniques and methods as well as their employability.
