   - Download {{:courses:b3b33vir:tutorials:hw2:hw2.zip|source code package}} and implement missing parts in module ''intrinsics.py'' (see below)
   - Get familiar with pinhole camera model, nonlinear distortion model and respective [[https://docs.opencv.org/3.4.3/d9/d0c/group__calib3d.html|calibration routines from OpenCV]]
-  - Calibrate camera intrinsic parameters (rational model without tangetial distortion)
+  - Calibrate camera intrinsic parameters
     * Implement function
       * ''intrinsics.calibrate''
     * Using functions
       * ''cv2.findChessboardCorners''
-      * ''cv2.cornerSubPix''
+      * ''cv2.cornerSubPix'' (limit search window size ''winSize'' to avoid excessive corrections)
-      * ''cv2.calibrateCamera''
+      * ''cv2.calibrateCamera'' (use the rational model without tangential distorion from the lecture: ''flags=cv2.CALIB_RATIONAL_MODEL + cv2.CALIB_ZERO_TANGENT_DIST'')
   - Convert camera intrinsics parameters (camera matrix and field of view)
     * Implement functions
