Basic concepts of Robot Vision
1. Camera Calibration: the process of obtaining internal and external parameters of the camera.
2. Vision System Calibration: determines the relationship between the camera and the robot.
3. hand-eye system: a robot vision system consisting of a camera and a manipulator.
4. Eye-in-hand: the visual system where the camera is mounted at the end of the manipulator and moves along with the manipulator.
5. Eye-to-hand: the camera is not mounted at the end of the manipulator and does not move with the manipulator.
6. Vision Measure/visual measure: measure the position and posture of the Target Based on the visual information obtained by the camera.
7. Vision control/visual control: Obtain the position and posture of the Target Based on Visual Measurement, and control the robot's position and posture as a given or feedback.
8. visual servo/visual servoing: visual information is used to control the robot's servo control.
9. Planar vision: the tested object is in a plane, and only the information of the object in the plane is measured and visually controlled.
10. Stereo Vision: Visual Measurement and Control of Object Information in three-dimensional Cartesian space.
11. Structured Light vision (structured light vision): uses a specific light source to illuminate a target to form a manual feature, which is measured by the camera. Structured Light vision simplifies Feature Extraction in image processing and greatly improves image processing speed.
12. Active vision: a visual system that actively lights the target or actively changes camera parameters.
13. Passive vision: passive vision uses natural measurements, such as binocular vision.
