The PMD Time of Flight sensor produces high-fidelity depth mapping indoors up to 6m. On the VOXL platform this sensor is mutually exclusive to the stereo cameras, meaning the stereo cameras need to be replaced with the TOF Add-on.
Requires VOXL System Image 2.3 or greater.
|Rate||5 - 45FPS in configurable option modes for distance / accuracy / framerate|
|Exposure Time||4.8 ms typ. @ 45 fps / 30 ms typ. @ 5 fps|
|Resolution||224 x 171 (38k) px|
|FOV (H x V)||117° x 117° (near field 100° x 80°)|
|Range||4 - 6m|
|Depth Resolution||<= 1% of distance (0.5 – 4m @ 5fps) <= 2% of distance (0.1 – 1m @ 45fps)|
|Time Sync||No physical pin, but the frame timestamp is measured with 50ns precision on a single clock. All of the sensors on the VOXL platform are timestamped for computer vision.|
|Dimensions||24mm x 10.6mm|
- 2D Dimensions: 24mm x 10.6mm
- 3D Model (STEP): MCAM-00005-TOF-A65.STEP
- 3D Model (SolidWorks 2020): MCAM-00005-TOF-A65.SLDPRT
The best approach to access TOF data on VOXL is to write an MPA client that listens to the voxl-camera-server pipe data. An example of that is here.
