自动缺陷检查技术正在日益取代 人们的视觉检查。对无缺陷部件 的需求推动了检查工序的发展, 从只测量少量样品部件进展到对部件 进行 100％全面检查,并用部件容差做为基准。几何部件缺陷的一般类型包括 形变、与规格的偏差,或漏装的零件。 为了有效地测量种种几何特性,检 查系统必须是快速、精确和可靠——非 接触式三维(3-D)光学测量系统必须满 足的要求。光检查系统分为三种类型: 单点,单线和面测量系统。大部分测量
Automatic defect inspection technology is increasingly replacing people’s visual inspection. The demand for non-defective parts drives the development of the inspection process, moving from just measuring a few sample parts to 100% full inspection of the part, using the part tolerance as a benchmark. Common types of geometric defects include deformation, deviations from specifications, or missing parts. In order to effectively measure the geometry, the inspection system must be fast, accurate and reliable - the requirements that non-contact 3D (3-D) optical measurement systems must meet. Light inspection system is divided into three types: single-point, single-line and surface measurement system. Most measurements
