Compatible ToF sensor setup with VOXL2 Mini
-
Hi,
We are trying to configure Voxl 2 Mini with the ToF sensor and a tracking camera with the , and we're having trouble with getting the ToF sensor to work. This is with the new ToF sensor and the new interposer you suggested for us to use.
The cameras are attached in the following way:
J7 <-> M0135 (JL) <-> M0014
J6 <-> M0172 (J1L) <-> M0170 <-> tof
The voxl suite we have on the board is: voxl-suite: 1.5.0To configure the cameras we run:
voxl-configure-sku
choosing options 23 (voxl-configure-sku) and 5 (pmd-tof ov7251 tracking).
The output was the following:Your answers would construct the following SKU: family code: MCCA-M0104 (voxl2-mini-board-only (MCCA-M0104)) compute board: 6 (voxl2-mini) hw version: 1 cam config: 05 modem config: () tx config: () extras config: () SKU: MCCA-M0104-C05-T0-M0-X0 This sku will be saved to persistent memory so VOXL will remember what it is installed in, even between system image flashes.So we run:
voxl-configure-mpaandrebootTo inspect the cameras, we run
voxl-inspect-cam -a, but we were able to see only the tracking camera:| Pipe Name | bytes | wide | hgt |exp(ms)| gain | frame id |latency(ms)| fps | mbps | format | tracking | 307200 | 640 | 480 | 2.51 | 51 | 204 | 11.5 | 30.0 | 73.7 | RAW8So we restarted the service

But making these changes to the
/etc/modalai/voxl-camera-server.conffile didn't seem to change the actual configuration used, as reported when runningvoxl-camera-serverin terminal.Do you have any suggestions for how we can get this working?

Additional debugging:
Moreover, we test some other configurations:
- J7 <-> M0135 (JL) <-> M0014
- J6 <-> M0172 (J1L) <-> M0170 <-> tof
We copied the files:

We also swapped the tracking camera and the ToF sensor (J6 <-> J7), copying the
.binfiles according to and adjusting the ID numbers. -
@Morten-Nissov , please only put one sensormodule with the correct slot number in
/usr/lib/camera. This will help eliminate any confusion.Also, does
voxl-camera-server -lactually detect your TOF module?It seems your camera id is actually incorrect. It should be 1. The slot id is 2 (which is tied to the hardware), but the software camera Id is assigned as the cameras are probed in each slot.
voxl-camera-server -lwill tell you (at the top) which cameras have been detected, which slot and camera ids.Alex

@Alex-Kushleyev Thanks for getting back to us so quickly.
We removed all the

Thanks for your help,

@Luca-Zanatta , I believe your issue is that you are specifying the wrong type of TOF sensor. There are two types:
- pmd-tof (old, EOL)
- pmd-tof-liow2 (a.k.a
irs2975c)
Based on your sensor id (
Slave Address: 0x007A, Sensor Id: 0x2975), you have pmd-tof-liow2, so you should runcamera-server-config-helper tracking:ov7251:0 tof:pmd-tof-liow2:1).When you configured for
pmd-tof, the camera server config was incorrectly set for the old TOF sensor, which has resolution of 224x1557. The new TOF sensor has resolution of 240x1629Please try. Sorry i did not catch that earlier.

@Alex-Kushleyev @Luca-Zanatta I am also facing the same issue, can you please tell how to solve resolution problem.
I have tried to manually add preview width and preview height in vim /etc/modalai/voxl-camera-server.conf But when i run voxl-camera-server it still gives previous resolution 240*1557 and hence pmd-tof is not detected. -
The preview width and height parameters are always in the camera config file, so if you added them, they are duplicates (and will be ignored).
Please read through this thread as it has pretty detailed explanation how to configure the correct tof sensor (old or new) for a custom configuration.
Camera-server-config-helper is indeed helpful. If you use it correctly, you should not have to manually modify the resolution in the config file.
If you still cannot get this to work, please let me know what cameras you have plugged in (and which camera ports) on your voxl 2 mini.
Alex
