Running the intrinsic calibration #5

Open lambozan opened 6 years ago

Thanks for the uploading of this useful code. While something goes wrong when I run the intrinsic calibration. My command is: bin/intrinsic -p chessboard -n 15 -W 25 -H 25 /home/usr1/CalibImg/ImageChessBoard4/left/*.bmp /home/usr1/CalibImg/ImageChessBoard4/left/intrinsic.json Then the terminal shows: Traceback (most recent call last): File "bin/intrinsic", line 178, in main() File "bin/intrinsic", line 128, in main selected_indices = select_images(image_points, opts.num) File "bin/intrinsic", line 104, in select_images imgpoint = image_points[imlist[-1]] IndexError: list index out of range Could I ask how to fix it?

Is the path correct ? this would happen if imlist is empty. Have you escaped the wildcard ?

I get the same problem

SalimKayal commented 4 years ago

How many calibration images do you have ?

How many calibration images do you have ?

Thank you for your reply, I used 10 pictures to calibrate the intrinsic matrix.

SalimKayal commented 4 years ago

if you use --num=10 or less does it still happen ?

I use command like the style "bin/intrinsic -o /home/user1/frames_with_grid -s /home/user1/camera1/selected_frames_with_grid home/user1/camera1/frames/*.bmp /home/user1/camera1/intrinsic.json", the above problem occurred.

Then I use command like the style "./bin/intrinsic --num 10 --width 6 --height 9 --pattern chessboard --full_output /home/lds/workspace/multicamera-calibration/data/frames_with_grid --select_output /home/lds/workspace/multicamera-calibration/data/selected_frames_with_grid /home/lds/workspace/multicamera-calibration/data/MySet/*.png /home/lds/workspace/multicamera-calibration/data/intrinsic.json" there is such a problem "intrinsic: error: unrecognized arguments: /home/lds/workspace/multicamera-calibration/data/MySet/left03.png /home/lds/workspace/multicamera-calibration/data/MySet/left04.png /home/lds/workspace/multicamera-calibration/data/MySet/left05.png /home/lds/workspace/multicamera-calibration/data/MySet/left06.png /home/lds/workspace/multicamera-calibration/data/MySet/left07.png /home/lds/workspace/multicamera-calibration/data/MySet/left08.png /home/lds/workspace/multicamera-calibration/data/MySet/left09.png /home/lds/workspace/multicamera-calibration/data/MySet/left10.png /home/lds/workspace/multicamera-calibration/data/intrinsic.json"

you forgot to escape the wildcard. it got expanded by your shell instead of the script
