    I have some questions regarding VOXL2 -
    Scalability & Coordination – Can multiple VOXL 2 units be networked or coordinated to work as a swarm across large orchard areas?
    Sensor Support – We plan to use multispectral or hyperspectral imaging (e.g., NIR and RGB). How easily can VOXL 2 integrate such sensors, including thermal or FLIR modules?
    Flight Control & Outputs – Since VOXL 2 is a companion computer with PX4, what are the options for connecting propulsion systems, sensors, or PWM outputs?
    Development Tools – What SDKs, ROS 2 support, or AI/ML integration tools are available for real-time disease detection models?

    Thank you

    Hello @daz_22 ,

    The ideal intrinsics of the IMX412 camera module (M0161) are as follows:

    Full resolution:

    focal length : 1999 (~2000) pixels principal points: 2028, 1520 (for full frame image, such as 4056x3040 or 4040x3040)

    2x2 Binned resolution

    focal length : 1000 pixels principal points : 2028/2, 1520/2

    For other resolutions, you can adjust the principal points to be half of the width and height because the cropped image (in case of 3840x2160 or 1920x1080) will be centered.

    The lens model is fisheye and you should set the distortion coefficients to zeros unless you calibrate them.

    If you are going to calibrate the camera using voxl-calibrate-camera, it is very slow at full resolution, so i suggest calibrating at half resolution.

    Here is an old calibration result I found for one of these cameras, just for reference:

    %YAML:1.0 --- M: !!opencv-matrix rows: 3 cols: 3 dt: d data: [ 999.5391440104593, 0.0, 1016.522606127024, 0.0, 998.2572561064064, 750.2875966666587, 0.0, 0.0, 1.0 ] D: !!opencv-matrix rows: 4 cols: 1 dt: d data: [ -0.02176119101007071, 0.01025514886831165, -0.01688007838706262, 0.006525270203215156 ] reprojection_error: 0.72238 width: 2020 height: 1520 distortion_model: fisheye calibration_time: "2024-11-15 16:38:58"

    @tom Oh I have a important question, please help me reply soon.
    I see comment in this post: “ MCCA-M0125 USB3.0 / UART Expansion Adapter” can use to connect to Ethernet. So if it can use MCCA-M0125 USB3.0 / UART Expansion Adapter to connect HDMI. Thanks so much for your reply.

    You can obtain Hexagon SDK 4.1.0.4 for the flight controller build environment described in this document: https://gitlab.com/voxl-public/rb5-flight/rb5-flight-px4-build-docker at the ModalAI developers web site under EULA protected downloads in addition to getting it directly from Qualcomm. https://developer.modalai.com/asset/view/184

    Our company, 3i(in Korea), develops and supplies software solutions related to digital twin technology.
    Currently, we perform indoor measurements manually, but we are exploring the possibility of using drones to automate this process.
    During our research, we came across the drones offered by ModalAI and believe that your products may be well-suited to our needs.
    Before proceeding, I would like to confirm the following:
    Is it possible to connect additional hardware, such as a 360° camera, via Bluetooth or USB?
    Does the drone come with basic collision avoidance logic already implemented?
    Given our intended use case, would the Starling 2 Max be the most suitable option, or would you recommend another development kit that may be more appropriate?
    Do you offer international shipping to South Korea? If so, what are the shipping options, costs, and estimated delivery times?
    Are there any export restrictions for this product (especially with the battery and radio module included)?
    Could you provide the HS Code used for customs declaration?
    Is it possible to receive a proforma invoice for payment processing?
    Your advice will help us determine the best configuration for our research needs and proceed with the purchase.
    Thank you for your time and support. I look forward to your response.
