First Claim
1. A computer program stored in a non-transitory medium from which the program can be executed by a computer, for determining a volume for a three-dimensional vehicle from at least two digitized images of the three-dimensional vehicle, the computer program further comprising:
- an image acquisition group of instructions for receiving at least two two-dimensional images of the three-dimensional vehicle in a computer-readable format, wherein a first image of the two-dimensional images is acquired in a first view and a second image of the two-dimensional images is acquired for a second view that is a depth or width view relative to the first view;
a feature detector group of instructions that are executed to detect a shape and dimensions of features, including features that are smaller than the two-dimensional images of the vehicle;
a reference detector group of instructions that are executed to determine dimensions between reference points detected in, or manually entered for, the two-dimensional images of the vehicle;
a display group of instructions for displaying images of a vehicle on a visual display, including a display of symbols allowing manual entry of data representing at least one of;
a vehicle model and dimensions for selected features of the vehicle; and
a measurement calculator group of instructions that are executed to determine measurements about the three-dimensional vehicle in the image including a volume of the three-dimensional vehicle, from the dimensions of automatically detected features and from the data that has been manually entered into the computer.

Abstract
The invention provides a method and a computer program stored in a tangible medium for automatically determining a volume of three-dimensional objects represented in two-dimensional images, by acquiring at two least two-dimensional digitized images, by analyzing the two-dimensional images to identify reference points and geometric patterns, by determining distances between the reference points and the component objects utilizing reference data provided for the three-dimensional object, and by calculating a volume for the three-dimensional object.
