This paper addresses the problem of calibrating a pin-hole camera from images of 1D objects. Assuming a unit aspect ratio and zero skew, we introduce a novel and simple approach that uses four observations of a 1D object and requires no information about the distances between the points on the object. This is in contrast to existing methods that use two… CONTINUE READING
