When you upload the side image of a Cylinder Ttarget to the Target Manager, you must consider the actual shape and circumference of the object. As the Target Manager requires the defined parameters and the uploaded images to have exact dimensions, it is an obligation to properly calculate the shape that you work with.
To make sure that the uploaded images correctly encapsulate the flat body of the real physical object, the flat body-part representing the side surface of a cylinder or cone object is calculated as an rolled out planar surface. The mathematics presented here are particularly relevant when the shape of the object is a cone or a conic frustum. We present the calculations for the conical, cylindrical, and the conical shaped objects.
The following figure shows a generic conic frustum shape, which represents the most general case for conical Cylinder Targets, and its key geometric parameters.
