สมมติฐาน
Controlling reflection with a repeatable LED and camera geometry will make shallow defects observable before model training.
การตั้งค่าและฮาร์ดแวร์
Dark glossy injection-moulded parts on a fixed inspection bench; one part at a time and a human-reviewed label set.
Industrial camera · LED bar · Jetson Orin Nano Super · Custom YOLO · TensorRT
วิธีทดสอบ
Capture the same part under candidate angles, record lighting and working distance, then compare the reviewer's defect visibility before training.
ผลลัพธ์
The geometry exercise exposed lighting as the first decision. No publishable precision, recall or throughput number has been approved.
สิ่งที่ลองแล้วไม่ได้ผล
- A flat front light produced glare that hid shallow sink marks.
ข้อจำกัด
- Lighting and camera geometry must be re-tested for each installation.
- The internal set is not a production acceptance set.
สิ่งที่จะทำต่อ
- Create a site-specific capture protocol and label a balanced acceptance set.
- Repeat the test at the target line speed before comparing models.
