The PR resolves the issue for triangle Weights used by debevec algorithm being non zero at extremes.
It resolves#24966
The fix needs ground truth data to be changed in order to pass existing tests. PR to opencv_extra: https://github.com/opencv/opencv_extra/pull/1253
Fix Robertson Calibration NaN Bug
* add epsilon value for numerical stability in robertson merge
* update test to use range based for loop
* add comment to test
* move the epsilon
* address test comments
fix windows build warnings
fix vector type for tests
update tests
make threshold float
address test comments
fix tests and move epsilon again
* use scalar::all, move epsilon, and remove print
* trying to fix the custom AVX2 builder test failures (false alarms)
* fixed compile error with CPU_BASELINE=AVX2 on x86; raised tolerance thresholds in a couple of tests
* fixed compile error with CPU_BASELINE=AVX2 on x86; raised tolerance thresholds in a couple of tests
* fixed compile error with CPU_BASELINE=AVX2 on x86; raised tolerance thresholds in a couple of tests
* seemingly disabled false alarm warning in surf.cpp; increased tolerance thresholds in the tests for SolvePnP and in DNN/ENet
- removed tr1 usage (dropped in C++17)
- moved includes of vector/map/iostream/limits into ts.hpp
- require opencv_test + anonymous namespace (added compile check)
- fixed norm() usage (must be from cvtest::norm for checks) and other conflict functions
- added missing license headers
