雷射振鏡掃描系統是一個已經發展成熟的設備,常被應用於各種需要雷射的場合,如材料加工、醫療手術、雷射投影等。而隨著自造者運動的興起,個人化可攜式的雷射振鏡掃描系統漸漸發展起來,如何運用尋常的工具對其進行有效的校正也成為必要的技術。
本論文研究使用平台式掃描器與智慧型手機這兩種尋常的工具,利用電腦視覺的技術校正以步進馬達致動的雷射振鏡掃描系統,並基於工具的不同提出兩套簡單而有效的校正方案。以平台式掃描器進行校正的方案精確度較高,校正後雷射振鏡掃描系統校正後的位置誤差可降低至0.08 mm;以智慧型手機進行校正的方案操作流程較為便捷,校正後雷射振鏡掃描系統校正後的位置誤差可降低至0.15 mm。希望藉由此研究讓雷射振鏡掃描系統的校正技術能真正地走出工廠,進入廣大的自造者們手中。
Laser galvanometric scanning system is a well developed device, which is often used in many laser applications, such as material processing, medical surgery and laser image projection. As the raise of makers, personal laser galvanometric scanning system is also begin to develop. Thus, an easier calibration method with cheaper tools for the personal laser galvanometric scanning system is essential.
This research uses flatbed scanner and smartphone to calibrate a laser galvanometric scanning system which uses step motor instead of galvanometer, by using computer vision technology. We provide two calibration scheme, the first one uses flatbed scanner to do the calibration which has higher precision and the second one uses smartphone to do the job which is more user friendly. The former calibration scheme reduces errors of a laser galvanometric system to about 0.08 mm, and the later reduces errors to about 0.15 mm. Hope that with the calibration scheme provided by this research, the calibration technology can really be used by makers around the world.
