Understanding Robot Vision
Vision is the most important sense for robots operating in unstructured environments. Modern robots rely on multiple vision sensor types working together to perceive their surroundings comprehensively.
Vision sensors convert physical light (visible, infrared, or structured projection) into electrical signals that robot controllers can process. The choice of vision sensor dramatically impacts what a robot can accomplish.
👁️ Passive Vision
- • RGB cameras
- • Stereo vision systems
- • Thermal cameras
- • Relies on ambient light
💡 Active Vision
- • Structured light sensors
- • Time-of-flight cameras
- • Laser scanning
- • Emits own light signal
