文摘

Rolling shutter blur prevents accurate defect detection using microbolometer cameras. A time delay compensation method is designed for thermal cameras. Inter-frame delays are compensated by properly chosen trigger properties. Intra-frame delays are estimated with an accuracy of 16 μs using low cost equipment.
