A machine-vision system for inspecting an object is described. This system includes a light source, an imager, and a computer. It can be used to obtain dimensional and geometric information of the manufactured part.
The light source provides projected patterned light on the object useful to obtain a 3D geometric information about the object. The imager has a reception optical axis that intersects the object when the machine-vision system is in operation. The imager may include at least three rows of imaging pixels positioned to receive light shone onto the object by the light source. The computer system calculates three-dimensional object-geometry data of the object using signals from the imager, and computes at least a first characteristic plane and a second characteristic plane of the object from the calculated object-geometry data. The method also provides a process for obtaining and manipulating image data to determine the characteristics of the parts.
