TOWARDS ROBUST SELF-CALIBRATION FOR HANDHELD 3D LINE LASER SCANNING
structured light self-calibration laser scanning 3D reconstruction
2018/3/5
This paper studies self-calibration of a structured light system, which reconstructs 3D information using video from a static consumer camera and a handheld cross line laser projector. Intersections b...
A METHOD FOR SELF-CALIBRATION IN SATELLITE WITH HIGH PRECISION OF SPACE LINEAR ARRAY CAMERA
Space camera Self-calibration Optical auto collimation Focal length the optical axis
2016/7/4
At present, the on-orbit calibration of the geometric parameters of a space surveying camera is usually processed by data from a ground calibration field after capturing the images. The entire process...
This paper proposes a new, integrated method for the self-calibration of 3D laser range cameras (LRCs) and corresponding
systematic error models. Unlike other recently-proposed methods that consider ...
Self-Calibration and Metric Reconstruction from a Single Image
Calibration Model based Vanishing Points
2015/12/16
It is well known that vanishing point based analysis requires images with strong perspective effects due to wide angle lenses, close
objects, and often oblique viewing angles. Aerial imagery, however...
