Method for camera calibration of range imaging system by use of neural network

摘要

A method and an apparatus for acquisition of calibrated three dimensional data from camera image. The apparatus for acquisition of calibrated three dimensional data from camera image includes a cameral, alight source and an image processing computer. The camera acquires a light strip image of a target object. The light illuminates light strip to the target object and provides information about the illumination angle form base line (or reference line). The image processing computer obtains image and information about the angle theta of light plane from base line; computes connection strength of neural network and acquires calibrated three dimensional data in neutral network based on the obtained information. The mapping relationship between a control point in the three-dimensional space and a control point projected onto the two-dimensional image plane and illumination angle of light source to control point are derived by the neural network circuit.
