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.
