Abstract: There are many object detection algorithms that have performed well on public datasets, and they can be used in product defect detection. But there are still many details, which can affect the detection performance of actual product defect detection, need to be optimised. In this paper, we design a defect detector, called feature pair pyramid (FPP) detector, and optimise it for specific industrial application using three methods. Then we use FPP detector to detect defects of metal can products of an enterprise. The experimental results show that our FPP detector is more effective in detecting small size defects. The performance (AP@0.5) of our detector is better than current state-of-the-art detectors.
