1. A computer program stored in a tangible medium for determining a volume for a three-dimensional object from at least two digitized images of the three-dimensional object, the computer program further comprising: an image acquisition group of instructions for receiving at least two two-dimensional images of the three-dimensional object in a digital format; a feature detector group of instructions that are executed to detect features of the three-dimensional object in the image; a reference detector group of instructions that are executed to organize features with reference positions and shapes in the image; a display group of instructions for displaying the images of a vehicle on a visual display for creation and editing of symbols representing features; and a measurement calculator group of instructions that are executed to determine measurements about the object in the image including length, height and width, which are then calculated to determine a volume of the three-dimensional object.
