基于结构光的三维非接触测量系统的原理及校准
Principles and calibration of structured light based 3D non-contact measurement systems
【摘要】 近年来,随着机加工行业的飞速发展和非接触测量技术测量准确度的不断提高,接触式三维坐标测量技术由于测量原理的限制,在测量效率以及数据处理方面已经无法满足要求。基于结构光的三维非接触测量系统通过结构光视觉原理,将一定模式的结构光投射于被测物表面,形成可视特征并通过数学模型进行运算得到被测物体的表面特征,这种测量方式逐渐的在产品质量控制过程中得到了越来越广泛地应用。该系统有着测量效率高、数据处理全面、应用范围广的特点,广泛应用于汽车制造、机械加工、航空航天等领域。通过对测量原理及校准方法的介绍,并进行校准方法的不确定度评定,得出该方法的可行性及可靠性。
【Abstract】 In recent years, with the rapid development of the machining industry and the continuous improvement in the accuracy of non-contact measurement technologies, contact-based three-dimensional coordinate measurement technology has become unable to meet the demands in terms of measurement efficiency and data processing due to the limitations of its measurement principles.The three-dimensional non-contact measurement system based on structured light, which employs the principle of structured light vision, projects a patterned structured light onto the surface of the object being measured.This creates visible features that are calculated using mathematical models to obtain the surface characteristics of the object.This measurement method has been increasingly applied in the process of product quality control due to its high measurement efficiency, comprehensive data processing, and wide application scope.It is widely used in fields such as automotive manufacturing, machining, aerospace, and more.By introducing the measurement principles and calibration methods, and conducting an uncertainty evaluation of the calibration methods, the feasibility and reliability of this method are determined.
