高动态范围条纹结构光在机检测技术及应用进展
On-machine detection technology and application progress of high dynamic range fringe structured light
摘要
Abstract
Fringe structured light technology is a non-contact measurement method,which has developed rapidly in recent years and provides a new solution for on-machine detection in mechanical processing.However,the accuracy of structured light for on-machine detection is compromised by the convoluted light-ing in machining environments and metal parts'high reflectivity,leading to inaccurate measurements.Apply-ing high dynamic range(HDR)technology to structured light detection can reduce the effect of high re-flectivity,achieving the measurement of metal parts in complex scenes.This paper introduces the measure-ment principle of structured light and summarizes the challenges of on-machine detection for HDR struc-tured light.Subsequently,this paper provides a comprehensive review of HDR structured light technology.In the context of on-machine detection of mechanical processing,the HDR technology based on hardware equipment and the HDR technology based on stripe algorithm are discussed and analyzed,respectively.Fol-lowing this,different technologies are summarized according to the requirements of on-machine detection.The advantages and disadvantages of various methods are presented,and the applicability of on-machine de-tection is compared.Finally,the potential applications are analyzed,and the technological prospects will be proposed in combination with the research hotspots of advanced manufacturing technology and precision measurement in recent years.关键词
