Abstract: Embodiments for a program product for determining the two-dimensional size of an object in an image are provided. The program product includes a non-transitory processor readable medium having software stored thereon. The software, when executed by one or more processing devices, is configured to provide an image of the object obtained by the camera and a range from the camera to the object. The software is also configured to determine dimensions of the object in pixels of the image and determine a pixel-to-length conversion factor for the object based on the range from camera to the object and a focal length of the camera. The software is also configured to calculate two-dimensional dimensions of the object in a unit of length, wherein the two-dimensional dimensions correspond to a plane normal to the camera and output the dimensions of the object to a user.
