What are the components of mobile robot vision system?

Intelligent mobile robot is a comprehensive system integrating environmental perception, dynamic decision-making and planning, behavior control and execution.Mobile robot is a kind of intelligent robot that works in complex environment and has self-organization, independent operation and independent planning. It integrates computer technology, information technology, communication technology, microelectronics technology and robot technology.

Mobile robot vision system refers to the vision system of mobile robot, including image acquisition through sensors, and image processing through computer processors.Generally speaking, the visual system of mobile robot consists of the following parts:

1, one or more light signal generators, can be natural light signal transmitters such as object ambient light reflected light, or artificial light signal transmitters such as flashlight, laser light source,

2. One or more sensors used to receive light signals reflected from the structure, such as a camera. The image produced by the camera can be said to be the original image, but the sensor may not be an optical sensor, but may also be an ultrasonic sensor.

3. Image acquisition card converts the received image into binary code that can be recognized by the computer for subsequent processing.

4. Enhance and denoise the image, and remove and correct the defects.

5. The transformed image is described by image storage and the necessary information is given.

6. Feature extraction, deriving relevant information according to various laws, algorithms and other criteria.

7. Target recognition is used to compare the extracted image features with those recorded in the training stage.Recognition may be global recognition, local recognition or zero recognition.Regardless of the result, the robot must decide to take the corresponding action according to the result of the recognition process.At this stage, any errors may cause uncertainty in performance.
