Depth Determination Method for a Trailer-Truck Test-Bed

A camera is considered as a good sensing device to obtain visual information from its surrounding environment. In a three dimensional space, a camera has a two dimensional plane. Projection of an object on this plane creates a two dimensional projection and loses information of the third dimension. A single projection is not enough to retrieve the lost third dimensional information about the object. Thus it makes it difficult to use a single camera as a sensing instrument. In this project, we have developed a method that determines the three dimensional information using a single camera. The method utilizes an assumption of the camera being in motion, allowing it to take projections on unaligned camera planes at different positions. A mathematical comparison of these projections gives us a deterministic value of depth of the surroundings from these camera planes.
