METHOD AND APPARATUS FOR DIMENSIONING OBJECTS

Abstract:

A method of dimensioning an object includes: controlling an image sensor of the dimensioning device to capture image data representing the object; controlling a rangefinder of the dimensioning device to determine an object depth relative to the image sensor; detecting, in the image data, image corners representing corners of the object; determining a ground line and one or more measuring points of the image data based on the detected image corners; determining one or more image dimensions of the object based on the ground line and the one or more measuring points; determining a correspondence ratio of an image distance to an actual distance represented by the image distance based on the object depth, the ground line, and the one or more measuring points; and determining one or more dimensions of the object based on the one or more image dimensions and the correspondence ratio.
