Abstract: A high speed method and apparatus for accepting and rejecting an object by identifying specific surface features of interest of an object includes providing at least one non-contact sensor capable of measuring a characteristic of a surface and a transporter system for creating relative motion between the sensor and an object while repetitively making measurements of a surface of the object with multiple readings being taken with the sensor at each of multiple locations in order to create a data set. A data analysis system mathematically processes the surface characteristic data and positional data into surface feature data which represents three-dimensional surface features of the object.
