System and method for efficient 3-D reconstruction of objects using a telecentric Line Scanner Camera

摘要

Problem to be solved: to provide a method and apparatus for reconstructing a three-dimensional scene using at least two line scan cameras having a telecentric lens.A system and method for enabling stereo reconstruction using a line scan camera of a general purpose in the present invention will be described.As a result, the accurate alignment of the sensor lines is not required.The method of the present disclosure requires that a telecentric lens be mounted on a line scan camera instead of a perspective lens.In this case, the image can be correctly parallelized by stereo reconstruction.Efficient stereo matching can be achieved by using paralleled images.The method includes a camera model and calibration procedure that allows accurate modeling of the imaging process, including modeling of the lens distortion, even if the sensor line is not accurately positioned behind the main point.This ensures high accuracy of the obtained three-dimensional reconstruction.Diagram
