@Matt-Turi Hi there, im trying now with the flir thermal camera. However it`s looking for a intrinsics cal file. How can i find/create this file?

@Matt-Turi I`m using the Voxl apq8096, with version 0.1.4 it displays the tof camera but without features, I was able to fix the ERROR in get_data_over_range, requested timestamp must be >0 by adding some lines to your code, but still I have the 2 warnings mentioned above.

Hi there, i`m trying to use the voxl-feature-tracker with Tof camera, I was able to achieve this with voxl-feature-tracker V0.08 without any problem. However, when im trying to run the version 0.1.3, im getting the same warning all the time: WARNING: failed to track any points. I even tried to play with the new version 0.1.4 but I got new error and warning: ERROR in get_data_over_range, requested timestamp must be >0, WARNING: Failed to match, dropping frame.
Could you help me to fix these errors @Matt-Turi?

Im using the APQ8096

Hi there, can you please upload the new modalai-4.0.0 system image.

@Maxim-Temp Also please upload the voxl-cross docker image v2.2 .

Thank you for your fast reply, now i understand the concept of dev. I want to try the new sdk-0.9 but i need to download the system image v4.0.0. I went to your downloads page but this image is not there. only the previous VOXL Platform 3.8.0-0.7 is there.

Hello there,
I have been using voxl-tflite-server v0.3.0 with my changes for a project I was working on. However, with your latest updates I wasn`t able to build this package and docker-cross gave me these errors:
I was installing the dependencies with the command:
./install_build_deps.sh apq8096 sdk-0.7
Also, when im installing dev and not sdk-0.7 it seems to build it, but then I encounter with these errors:
1)voxl-tflite-server: error while loading shared libraries: libtensorflow-lite.so: cannot open shared object file: No such file or directory
2) sed: /etc/modalai/voxl-tflite-server.conf: No such file or directory
This is not the first time i encounter with that problem and it seems that it happens every time when you publish new sdk. For example, when I was working during a project on the apq8096-camera-server (sdk-0.7) I couldnt deploy the package to the voxl because it downloaded automatically the new voxl-camera-server (becuase of your new sdk-0.8).
You prevent me every time from working on specific versions. You should understand that i wont copy my code each time you publish new sdk...

Hello there,
While i was running the TOF IR camera ive noticed that the camera is displaying objects only up to 2 meters (altough it is written that it can go about 4-6 meters). Also, the brightness of the camera is very low and i can barely see the objects when they are a little bit far from the camera. How can i change these settings?

Hello there,
I`m running voxl-suite v0.7.0 because im using the TOF camera. When I compile and deploy the apq8096-camera-server (sdk-0.7) it installs automatically the voxl-camera-server (v1.1.0) which is sdk-0.8 which does not support the usage of the TOF camera... In Addition, I wasn't able to compile the voxl-camera-server (v0.2.0) and deploy it to the voxl version 3.8.0 (using voxl-cross V2.1).

Hi there,
I have been trying to run the voxl-tflite-server (apq8096) on the GPU with a my own model. I have followed your guide on how to create a custom model. However, when im trying to run my model im getting the error: "Segmentation fault":

@Matt-Turi Wow, thank you for updating me. I will try these models now

@Matt-Turi Thank you for your quick response. I will investigate further!

Hello there,
I have been trying to run the voxl-tflite-server (apq8096) on the GPU with the DeepLabV3 model. It worked well on the CPU, without any errors. However, when im trying to run it on the GPU, i don`t get any frames and i get the following errors:

And then the same repeating lines over and over again:
