Projector Calibration by "Inverse Camera Calibration"
The accuracy of 3-D reconstructions depends substantially on the accuracy of active vision system calibration. In this work, the problem of video projector calibration is solved by inverting the standard camera calibration work flow. The calibration procedure requires a single camera, which does not need to be calibrated and which is used as the sensor whether projected dots and calibration pat...
متن کاملRobotic Calibration Issues: Accuracy, Repeatability and Calibration
The groundwork for a contact calibration methodology using a touch probe is developed for an articulated robot arm. This solution is framed within current calibration and metrology issues in robotics based upon the kinematical mechanical design of a serial link manipulator. Accuracy, repeatability, and resolution are explored and a simplistic approach is taken. This exercise is intended to lay ...
متن کاملSTIS Calibration Enhancement: Wavelength Calibration and CTI
The Instrument Physical Modeling Group in the Space Telescope European Co-ordinating Facility has undertaken to examine aspects of STIS calibration and develop physical model based solutions where appropriate. Here we discuss two such aspects and the status of the model based solutions. The first concerns the derivation of dispersion solutions for the echelle spectroscopy modes. The second corr...
متن کاملCollaborative calibration: extending shape from motion calibration
In this paper, we summarize recent research results from a new technique of sensor calibration called Shape from Motion Calibration. We first present the basic technique, which is an eigenspace analysis, and show that it includes the rigor of least squares without the full burden of measuring all the applied inputs. Next we present new research that removes another constraint of the calibration...
متن کاملFlexible Calibration: Minimal Cases for Auto-Calibration
This paper deals with the concept of auto-calibration, i.e. methods to calibrate a camera on-line. In particular, we deal with minimal conditions on the intrinsic parameters needed to make a Euclidean reconstruction, called flexible calibration. The main theoretical results are that it is only needed to know that one intrinsic parameter is constant. The method is based on an initial projective ...
