Abstract
An arrangement in which three-dimensional measurement sensors are calibrated using linear translation of three flat plates, one orthogonal to the path, one sloping vertically, one sloping horizontally. Sensors for which linear interpolation applies need only calibrate two surfaces of the sensor volume for complete calibration. Two flat surfaces are adequate for calibrating a volume if one surface is used twice.
