@Chad-Sweet Any help on this issue?

Update :

I tried starting calibration with bigger checker board of size 7x9 with each square of length 0.08 as shown in the image attached but still no luck.

My VOXLCAM system image version is 3.3.0.

Hello,
I have custom printed checker board pattern 5x7 with each square of length 40 mm. With this checker board printed on A4 size paper I tried to kick start voxl-calibrate-camera for caliberating my stereo camera pair but this isn't working and on voxl-portal I cant see checker pattern been detected on stereo image overlay. So basically I couldn't proceed with the same.
I ran this command "voxl-calibrate-camera stereo -m -s 5x7 -l 0.04"

Please see attached image of voxl-portal which isn't able to detect pattern.

What can be the issue?

Also I tried running voxl-calibrate-camera on checkboard printed and stuck to wall and me moving camera to position board inside specified regions.

Hello @James-Strawson Thanks for reverting back. That would make my application to subscribe to point cloud pipeline instead of depth image. It would have been better if depth image was up-right and not inverted.

I have couple of queries over voxl-vision-px4 functioning :

• As per this document voxl-vision-px4 seems to be taking point cloud data from dfs_server (stereo camer's) and not from Tof. Can VOA work over Tof data?

• Is there any direct tool/library to convert point cloud data from Tof/DFS to convert into FLU (forward left up) frame since that's conventional frame over which most of the path planner's work?

@James-Strawson @Chad-Sweet Any inputs on this issue? I wanted to have normal non inverted depth image for my further computation from hal3 library itself to avoid additional hops in the application.

Hello,
My VOXLCAM system image version is 3.3.0. I have configured voxl-camera-server to take input from tracking + stereo + tof sensors with option '7' on voxl-configure-cameras, wherein I was able to get rotated stereo sensor stream.

My Tof depth sensor shows 180 degree rotated view which is inverted as compared to actual. How to rotate tof_depth sensor view by 180 degree again?

Hello,
We have procurred VOXL 2 development kit and I had few queries regarding hardware/software setup of front and rear stereo camera pairs.

• Are Fisheye lens camera OV7251 compatible with current VOXL-2 front and rear stereo camera flex CSI connectors? If yes please provide link to the compatible camera to buy.

• Is stereo camera calibration for VOXL-2 similar to VOXL-1 ? Is this link for camera caliberation relevant? Also is fisheye lens calibration supported?

@Eric-Katzfey Thank you for the great news.

Any tentative timelines for release of this add-on board?

Hello,
Thank you for releasing most awaited VOXL 2 platform. We have placed an order for VOXL 2 and should receive the same within few days.

We are working on Coaxial helicopter airframe on PX4 with VOXL-1 (We have VOXL 1 with us) and it had direct PWM lines for integrating servo needed for coaxial helicopter airframe. After going through VOXL 2 documentation I am bit worried about direct PWM control of servos since PX4 is now operating on RB5 DSP. I am aware of using MODALAI UART ESC for operating BLDC motors. Here are my queries.

• How to get direct PWM control of servo from VOXL-2 ?

• Can ModalAI ESC be used somehow for direct PWM servo control?

@parbat101 Probably you can try enabling "en_send_vio_to_qgc": true in your above shown config file? In my case I can arm drone in manual/position mode easily, just using mavros is the concern.
