Manual coloring

[Sau72]

I had tried workflow from video:

Part1 with extrinsic calibration camera is working great, i am seeing lidar scan that is colored by image. After it, i am saving calibration to file.
Part2, after loading session is showing all points by light green color. I am loading calibration and image directory, but changing index of image don't help to color pointcloud. All stay green.

Can any check working of software, for manual coloring?

Please check timestamps on the images.

Which timestamp? Here are equirectangular images with name format - frame_name%03d.jpg.
In "software single_session_manual_coloring.exe" here are index of images, but coloring don`t changing.

Ok, I get it. That is legacy app - I need to remove it, or at least rewrite it - it is for 360 cameras .
You need app camera_lidar_trajectory viewer. I am going to record a video on using that, but I am resolving some issue with wall time in maneye_controller.
App camera_lidar_trajectory loads:

• session
• camera folder
• extrinsics calibration
  Run it with -h to get how to setup it. You need your photos timestamp synchronized with lidar - those are e.g. cam0_1789428622914582427.jpg

Yes, it's for 360 camera and i am testing it. I had done first step with extrinsic calibration and save them to .reg file. But second step don't work, as in video))).

I am planning using it for scanning surface of cave entrance. Here are a little volume of coloring. Underground is coloring by height.

Mandeye clone with insta360 is difficult to sync or using mirror and led button
