    • VOXL-CAMERA-SERVER GOING DOWN

      I recently bought a Seeker and I'm experiencing some problems with the camera.

      1. The voxl-camera-server keeps going down (its enable but stops running). I have to restart it and then it runs for +- 30 secs and go down again.

      2. When I go to portal to see the feed of the cameras when the server is on I notice that the tracking cameras keep flickering... and lagging frames behind.. It is not a connection problem.. the other cameras work fine.

      I tried run journalctl and I got the following logs:

    • RE: Hires_snapshot snapshot-no-save is saving ?

      @Moderator said in Hires_snapshot snapshot-no-save is saving ?:

      voxl-camera-server

      What is the easiest way to update it ? I looks like apt update is not doing the job right.

    • RE: Hires_snapshot snapshot-no-save is saving ?

      Okay. I found the problem... its snapshot_no_save (instead of snapshot-no-save)... I believe the website docs and the internal terminal info have to be updated.. Thanks... Im just leaving the topic for people who might have similar issue.

    • Hires_snapshot snapshot-no-save is saving ?

      I believe there is a bug with the command voxl-send-command hires_snapshot snapshot-no-save... when I use it it still saves to the folder :/data/snapshots.. is this the expected behaviour ?

    • Voxl-mapper VIO

      In my current project I need a very accurate position estimation.. I wonder if the voxl-mapper service provides a better accurate position estimation than the VIO, since it probably uses a SLAM on top of the VIO. If so how can I acquire this data ? Thank You

    • RE: TOF and High Res Intrinsics

      @Darshit-Desai Then I believe you cannot do anything.. .the TOF is limited to certain surfaces and texture...

    • RE: TOF and High Res Intrinsics

      @Darshit-Desai If you have the 3D point cloud and you need to project it to a camera you need the intrinsics of the camera and the extrinsic... That's where I used the instrisic pf the RGB, on the image I sent you each point is a XYZ point projected to the RGB.. so with that you have the location in 3D space of the objects the camera is seeing.

    • RE: TOF and High Res Intrinsics

      @Caio-Licínio-Vasconcelos-Pantarotto The point cloud has less resolution than the depth view given by the TOF ? I didn't really explored it..

    • RE: TOF and High Res Intrinsics

      What do you mean by "running an object detector on a different resolution image and matching it with a sparse point cloud for getting 3d coordinates is inaccurate" ? You wanna use object detection on the RGB right ? Why you say that using the space point cloud is inaccurate ? Sorry I don't know much about this..

    • RE: TOF and High Res Intrinsics

      @Caio-Licínio-Vasconcelos-Pantarotto You also need to permute (1,0,2) the coordinates as they come from the sensor.. to be the way opencv expects
