15. IR Sensor
• IR Projecter – Projects a grid of IR dots
• IR Sensor – Detects IR dots and compute the
depth image
• RGBCamera – Similar to a standard webcam
IR?
• InfraRed

16. IR Sensor
IR dots
IR Sensor can
detect them
but we can’t

17. ToF CameraVS IR Sensor
ToF Camera
• Compute the depth precisely
• Better resolution
• Expensive
• Big
• Limited Distance
• Cannot detect LED under the sunlight
IR Sensor
• Compute the depth less precisely
• Lower resolution
• Cheap
• Small
• Cannot detect the depth under the sunlight
too
