Camera Calibration

This is an unofficial implementation of Z. Zhang, IEEE Transactions 2000. "A flexible new technique for camera calibration"

Data Prepare

All the data I used are in directory: data/left

Camera Calibration By OpenCV API

You can run prob1_6.py to see the camera calibration results and the undistrot images results

Camera Calibration

You can run main.py to see the camera calibration implementation without using function cv2.calibrateCamera().

Other Functions

pic_data.py: Prepare data.
dlt.py: Caculate Homography of each images.
intrinsics.py: Caculate the intrinsics matrix.
extrinsics.py: Caculate the extrinsics matrix.

Other notes

1. The intrinsics caculate by using OpenCV API :
   A =
   (534.07, 0, 0)
   (0, 534.12, 0)
   (341.53, 232.95, 1)
   

2. The intrinsics caculate by using my implementation:
   A =
   (532.806, 0, 0)
   (1.521, 529.066, 0)
   (350.359, 225.710, 1)
