Adding a new camera sensor

anttukoski

Are there any instructions how to add a new camera sensor to the Starling 2 device? A new camera sensor driver, tunings for it and configuring it for the use of the platform etc.

I guess this would be a standard Qualcomm driver chi-cdk/oem/qcom/sensor/XXX and tunings done with Chromatix to chi-cdk/oem/qcom/tuning/XXX but what is the build environment to use and how to do the platform configuration?

@anttukoski , can you please clarify your question :

Is your goal to attach an additional already supported ModalAI camera or to connect a 3rd party camera to Starling 2?

Thank you

@Alex-Kushleyev It's a 3rd party camera that is not supported by ModalAI.

@anttukoski , the only way, currently, to connect a third party camera to VOXL2 is using a USB interface, probably using the standard linux UVC driver (voxl-uvc-server would support this)

In order have access to the sources and tools to build the sensormodule camera drivers and tuning files, you would need a partner license from Qualcomm, since this is their terms.

Besides software integration, there is also hardware aspect to supporting the camera, making sure all the connections are properly routed to VOXL2.

Is there a specific camera that you have in mind (and a specific camera module)?

@Alex-Kushleyev I have access to Qualcomm tools and code (for example the chi-cdk code repository) and need to add a MIPI camera. I already got the HW, just replacing the imx678 with some other Sony camera modules. I'm also familiar with how to do the camera driver and tuning for Qualcomm platforms.

I'm just looking for the build environment for this platform to compile those drivers and if any platform configuration is needed.

Hi @anttukoski ,

The chi-cdk repository that you already have should contain the source xml files for the sensormodule and tuning files as well as the tools to build them. Additionally you would need a sensor.so (compiled from a cpp source) file for your new camera, which contains exposure and gain conversion functions for the specific camera. It seems you area already familiar with this.

VOXL2 uses the Qualcomm's standard format of camera drivers (from ubun1.0 main release), which you are already familiar, so if you build your sensormodule, tuning file and sensor.so, you should be good.

With this in mind, can you please let me know how we can help you? It seems that you already have everything you need.
