Hand-eye calibration for robot 3D surface scanning system

The camera and hand-eye calibrations are two important elements in the applications of vision robot.

Considering that in most hand-eye calibration methods, the basic equation needs to be solved, a new initial estimates method for robotic hand-eye calibration was proposed.

Eyes Location Method Based on Adaptive Edge Extraction;

At present,the eyes location algorithm based on pinkeye allocation needs artificial intervention.

A method of face detection and eyes location is proposed in this paper,which based on the distribution stableness in YIQ color space of human skins.

An eye location method of big angle rotation face at normal illumination

Whether a driver is fatigued can be reflected by his eyes during the course of driving,so it is practical to use the information about the driver s eyes to monitor driver s fatigue state,and among this,eye location is the key problem.

An algorithm for face detection and eye location in gray picture is presented in this paper, which integrates a series of weak classifier based on the face character of gray distribution, arithmetic of Principle Component Analysis(PCA) and morphological processing.
