Precision measurement methods are required in industry to measure the dimensions and shapes of manufactured parts. Laser scanning has emerged as the best method for collecting a large number of measurements from complex, curved surfaces like car body panels. In current practice, laser scanners are commonly manually programmed or operated. As a result, the inspection plan is inefficient and the part may not be completely scanned. This project will develop tools and techniques to automate and optimize the programming of laser scanners. The sub-problems to be solved include the following: - Finding a set of scan head positions, orientations and paths so that the entire part can be scanned efficiently. - Checking for and avoiding collisions between the scanning head and the workpart during the scanning process. - Optimizing the scanning process to minimize the total scanning time and maximize the scanning accuracy. This project will lead to significant improvements in the productivity and effectiveness of laser scanning in industry.

工业上需要精密测量方法来测量制造零件的尺寸和形状。激光扫描已成为从复杂曲面（如车身面板）收集大量测量数据的最佳方法。在目前的实践中，激光扫描仪通常是手动编程或操作的。因此，检查计划是低效的，并且部件可能未被完全扫描。该项目将开发工具和技术，以自动化和优化激光扫描仪的编程。要解决的子问题包括以下内容：-找到一组扫描头位置、方向和路径，以便高效地扫描整个零件。- 检查并避免扫描过程中扫描头与工件之间的碰撞。- 优化扫描过程，最大限度地减少总扫描时间，最大限度地提高扫描精度。该项目将显著提高激光扫描在工业中的生产力和效率。
