The input of the infrastructure calibration

[ptzu]

Hi, I try to run infra_calib, but it lacks the input map. I read Readme and it says that the map is generated by extrinsic calibration. However, I didn't see anything related to that when I read the code. Did I miss anything?

Hi @abcd40404 If you haven't solved it, you should need to run extrinsic_calib of the bin folder to get the map frames_5.sg, which is in CameraRigBA.cc. Then you can load it in infra_calib.
However, when I use the infra_calib, I can't fins the same Frame in the first code line boost::unordered_map<const Frame, FrameTag>::const_iterator it = m_frameMap.find(frame.get()) in LocationRecognition::knnMatch. I use the same data to build the map and run infra_calib.

Hi @yuyadanyadan Thanks for your reply. I have tried to run extrinsic_calib many times, but it didn't work. I typed "bin/extrinsic_calib -c . --input ../data/images/" to run it and moved the data generated from bin/intrinsic_calib to the build directory. Are these input data enough to run extrinsic_calib?

Hi @abcd40404 ./extrinsic_calib --calib /home/yuyadan/catkin_ws_rgbd_image_save/data1/ --camera-count 2 --f 421 --output /home/yuyadan/catkin_ws_rgbd_image_save/data1/ --data /home/yuyadan/catkin_ws_rgbd_image_save/data1/ --input /home/yuyadan/catkin_ws_rgbd_image_save/data1/rec/Odo.rec the code of reading odometry and image has been changed according to myself data. And you need to put the camera_0_calib.yaml, camera_1_calib.yaml to the folder of input parameter calibDir. you can track error from the code.

Hi @yuyadanyadan Sorry, I'm new to this, I would like to ask some stupid question. If I have only one camera, can I do this? What is odometry data actually? After I read the code, are estimate and event data necessary? Thank you.

[yuyadanyadan]

Hi, If you have one cam, the --camera-count 1. It can process one cam; the odometry data is x,y, yaw; the event data may be the GPS; the estimate ,event and mask which you can ignore

Thanks for your help!!

Hi, @yuyadanyadan After I tried it, I still can't run extrinsic_calib successfully. I got core dumped. I have camera_0_calib.yaml and images as input.

Could you give any advise?

same as mine, have you solved it? I would appreciate it if you would give some hints. @abcd40404

hi, i just wonder where did you guys find the infra_calib tool, i only got intrinsic_calib, exterinsic_calib and stereo_calib
