A Fast Positioning Technology for Compensation Hole of Automobile Brake Master Cylinder

The compensation hole of the automobile brake master cylinder is an important structural part for adjusting reservoir and pressure chamber cylinder. Its detection accuracy strictly controlled. However, because located on inner wall blind hole, existing method cannot meet testing needs. Therefore, this paper introduces SSD model into cylinder, realizes rapid positioning by means network fine-tuning. carried out self-developed detector. entire process time about 5s, high. We apply fine-tuning to which replaces traditional based human-computer interaction determine position hole. It has better faster speed, lays foundation subsequent size
