Camera caliberatiion is launching but screen is black in gui #37

HI, heathenish, I am using a USB camera and os1 64 lidars for calibration. I recorded the bag file including the topics that are mentioned in the attachment. Now when I am using the camera calibration lanch file just black windows open and nothing happens. Now I am not able to move forward. Now I am doing an intern in which I have to generate calibrated data set for a deep learning algorithm, where first I require camera and lidar intrinsic and extrinsic parameters. So Just tell me the steps that I have to follow to get the matrices. I have checked the issue portion in the GitHub where you solve all the issues of the persons, I want you to tell me the set of steps that I need to follow to get my camera and lidar calibrated. Again mentioning my lidar is ouster os1 64 and camera is a USB camera. so sir please tell me steps you think to approach the end result of calibration keeping the experience of issues of people with ouster in mind. So I don't have to mention individual step issues again and again. I will be very very grateful to you. From recording to getting rigid transform I need step by step procedure. I would be very grateful to you if you conclude the whole procedure in reply. I have been searching and using a lot of open-source ros package but no one gonna work for ouster, your one is supposed to run with ouster. Now I think I find the right one but I need your teaching please help me. I recorded my ros bag file simply and I don't know about timestamp and how it is set so kindly tell me how to properly record the rose bag file for this. I would be very thankful to you for this favor and I would document all the steps with pics and procedure and will put on your GitHub so others also follow this step by step. I need your help brother. We can also meet on google meet and you can just explain the whole procedure in 10 to 15 min, I will be much thankful to you. I am very thankful to you if you answer this asap as I have to make data set and use the algorithm afterwards probably in the internship era. I have attached issues and topics pics. kindly check them out. also, tell me how to edit launch files also. Again thank you very much.

I've got the same problem. Any recommendations?

Apologies for the inconsistencies, this was developed a long time back and has not been maintained since. I'm working on a new version that uses Open3D point picker and hopefully should resolve these issues. This new version should support more LiDARs and ROS2 as well.
