Abstract

A direct linear transformation (DLT) model is derived to describe the scan imagery of a line scan camera undergoing a uniform rectilinear motion. When more than five points on scan image and their corresponding three-dimensional space points are substituted in the DLT model, 11 coefficients are settled directly and linearly without any approximations. After that, the 11 physically meaningful line scan camera parameters are worked out from the 11 DLT coefficients through a group of analytical operations. The performance is tested and verified by both simulated experiment and demonstration of a real line scan camera.
