Using MSU-0161 Hi-res camera with MMSU-M0014 tracking camera.

vaibhavswami

Hi, I have purchased a 4k High-resolution, Low-light Sensor for VOXL (Starvis IMX412 w/ micro-coax & M12-style Lens) (MSU-M0161) with Micro-coax Adapter for VOXL 2 (MDK-M0155-1), a tracking camera (MSU-M0014-1-01) and a VOXL 2 Dual Camera Adapter (MSU-M0084) cable. I want to use this Hi-res camera along with the Tracking camera but the Micro coax adapter that comes with the Hi-res camera completely occupies the J7 port of the VOXL2. Is there a way I can use both these cameras together with the help of any adapter or converter or something?
Thanks.

@vaibhavswami ,

Yes, you can do it the following way:

make sure to power off VOXL2 before connecting / disconnecting cameras
connect your M0084 cable to VOXL2 J6
connect M0014 tracking camera to M0084 L (lower slot - this camera will be in slot 0)
connect M0161 + M0155 to VOXL2 J7 (this camera will be in slot 2)

Then generate a config file for voxl-camera-server using:

camera-server-config-helper tracking:ov7251:0 hires:imx412:1

This should generate updated config file /etc/modalai/voxl-camera-server.conf

Also, make sure to copy the sensormodule files (camera drivers):

cp /usr/share/modalai/chi-cdk/ov7251/com.qti.sensormodule.ov7251_0.bin /usr/lib/camera/
cp /usr/share/modalai/chi-cdk/imx412/com.qti.sensormodule.imx412_2.bin /usr/lib/camera/

See the following doc page for more info about camera drivers : https://docs.modalai.com/voxl2-image-sensors/#image-sensor-drivers-overview

After that, if you run

voxl-camera-server -l

that should list all the cameras that have been detected. You may need to stop the camera server if it is already running in the background (systemctl stop voxl-camera-server)

After confirming both cameras have been detected, you can just re-start the camera server systemctl start voxl-camera-server.

@Alex-Kushleyev Hi Alex, Thank you for your reply. I also have 2 pairs of stereo sensors, is it possible to use them together with the configuration which you have mentioned above? Basically, I want to use a Hi-res (with coax adapter), a tracking and two pairs of stereo sensors together.
Thank you.
