3D imaging allows machine vision systems to not only see their environment but to calculate where an object is located, as well as its orientation. Cameras used in 3D machine vision deploy laser triangulation to create a point cloud, or a digitized model of an object’s shape and location. Point clouds provide highly accurate and reliable inspection results. 3D mapping also accounts for unexpected variables, such as changes in contrast, color, lighting, and position. This type of machine vision is ideal for metrology, guidance, and defect detection applications that require high precision while tolerating variations in environment and objects under analysis.
