Specification Parameters Explanation

Depth Map resolution
Maximum number of rendered points (the resolution of camera sensor)
Point size
The average distance between two neighboring points on the point cloud of a plane located in the focus distance of the camera. Alternatively, the square of the point size is the average surface sampled by one 3D point on the plane scanned in the focus distance of the camera.
Relation of point size to scanning distance
Absolute accuracy
The accuracy of point measurement as the result of device calibration (can be understood as the space deformation). It is the standard deviation of the measurement error in the whole measurement range of the device.
Z noise
The standard deviation of the noise (measured on a diffuse surface with 80 percent albedo). The noise level describes the quality of the sensor to capture local surface details. The noise distribution of our sensor is similar to Gaussian distribution. Can be understood as temporal noise.
Maximum number of triggered frames per second, in fastest acquisition mode
Data acquisition time - best case
Fastest possible acquisition time
Data acquisition time - worst case
Longest expected acquisition time (bad lighting conditions, dark shiny objects)
3D points throughput
Number of 3D points that can be reconstructed in a second in sequential scans


Connectivity v1.png

Status LEDs meaning
⚫ Power status

Power cable connected

⚫ Processing unit connected

On => Suitable power connected
Off => Under/overvoltage, overcurrent

⚫ Reserved


⚫ Reserved


⚫ Ethernet speed

Off => Indicates 1 Gbps
On => Indicates 100 Mbps

⚫ Ethernet activity

Off => Link is down
Flashing Green => Link is up, with activity
Steady Green => Link is up, no activity
