Operating System / Platform: macOS
Compiler: Clang++ 15.0.0

Detailed description

I encountered a consistent failure in the Photo_CalibrateDebevec.regression test during OpenCV's photo module tests, regardless of whether OpenCL is enabled or disabled.

Failure Details

• Command:

  ./bin/opencv_test_photo --gtest_filter=Photo_CalibrateDebevec.regression

• Error:

  Expected: (max) < (0.131), actual: 0.193764 vs 0.131
  

• Test File: modules/photo/test/test_hdr.cpp (line 231)

Steps to reproduce

1. Build OpenCV with the following configuration:

 cmake -DCMAKE_BUILD_TYPE=Debug \
      -DOPENCV_EXTRA_MODULES_PATH=<path_to_opencv_contrib>/modules \
      -DOPENCV_TEST_DATA_PATH=<path_to_opencv_extra>/testdata \
      ..

   make -j4

2. Run the test:

   ./bin/opencv_test_photo --gtest_filter=Photo_CalibrateDebevec.regression

Issue submission checklist

• I report the issue, it's not a question
• I checked the problem with documentation, FAQ, open issues, forum.opencv.org, Stack Overflow, etc and have not found any solution
• I updated to the latest OpenCV version and the issue is still there
• There is reproducer code and related data files (videos, images, onnx, etc)
