Chapter 1Introduction

Gan, Zhongxue; Tang, Qing

Pages: 1 –19

[When an industrial robot is integrated with a vision sensor to form a robotic vision system, it becomes more flexible and intelligent. Industrial robots are originally designed for the tedious and repeated work, where the robot can be programmed in advance. It lacks of flexibility to handle the...

Chapter 3Laser Stripe Sensor Calibration

Gan, Zhongxue; Tang, Qing

Pages: 41 –91

[The purpose of laser stripe sensor calibration is to identify its intrinsic parameters and extrinsic parameters. Extrinsic parameters contain information about the sensor position and orientation relative to a reference coordinate frame. The physical meaning of intrinsic parameters varies,...

Chapter 4Calibration of a Robot Visual System

Gan, Zhongxue; Tang, Qing

Pages: 93 –141

[Industry is now seeing a dramatic increase in robot simulation and off-line programming (Motta, 2004; Mitsi, 2005; Swider, 2007). In order to use off-line programming effectively, the simulated workcell has to be identical to the real workcell. This requires a more efficient and accurate robot...

Chapter 5Image Processing of Laser Structured-Light Based Vision System

Gan, Zhongxue; Tang, Qing

Pages: 143 –164

[For laser stripe sensors there are two types of image processing tasks. One is to find locations of the control points in the calibration target. This is usually for the calibration procedure. The other is to find the center position of the laser line, which is used for the reconstruction...

Chapter 6Robot Kinematic Calibration

Gan, Zhongxue; Tang, Qing

Pages: 165 –192

[When an industrial robot is integrated with a laser sensor, it can be used as a coordinate measuring machine. We call the system a robot coordinate measuring machine (RCMM). To have RCMM achieve its highest possible accuracy, a trio of calibrations are introduced. In order for the robot to use a...

Chapter 7Visual Sensing and Control-Laser Sensor Based Robot Applications

Gan, Zhongxue; Tang, Qing

Pages: 193 –247

[In this chapter various laser sensors based robot vision systems and their applications are presented. Three kinds of visual sensing and control applications are discussed including measurement and inspection, identification and localization, and visual servoing. In the area of measurement and...
