An Adaptive Threshold Method for Light-knife Center Acquisition

WU Jian bo, CUI Zhen, ZHAO Hong, TAN Yu shan (Laser & Infrared Institute, Xi'an Jiaotong University, Xi'an 710049, China)$$$$  
The paper discusses several common methods used to acquire the light-knife center, and analyzes their defects. A new adaptive threshold method is proposed, which combines the extremum method with the threshold method and the barycenter method. The new method eliminates the disadvantages of the previous methods such as the noise and realizes the precise orientation. The method is characterized by good stability, high precision and high speed, etc.
