app	Merge pull request #27230 from sirudoi:4.x videoio: add Orbbec Gemini 330 camera support #27230 ### Pull Request Readiness Checklist See details at https://github.com/opencv/opencv/wiki/How_to_contribute#making-a-good-pull-request - [x] I agree to contribute to the project under Apache 2 License. - [x] To the best of my knowledge, the proposed patch is not based on a code under GPL or another license that is incompatible with OpenCV - [x] The PR is proposed to the proper branch - [x] The feature is well documented and sample code can be built with the project CMake ### Description of Changes #### motivated： - Orbbec has launched a new RGB-D camera — the Gemini 330. To fully leverage the capabilities of the Gemini 330, Orbbec simultaneously released version 2 of the open-source OrbbecSDK. This PR adapts the support for the Gemini 330 series cameras to better meet and respond to users’ application requirements. #### change： - Add support for the Orbbec Gemini330 camera. - Fixed an issue with Femto Mega on Windows 10/11; for details, see [issue](https://github.com/opencv/opencv/pull/23237#issuecomment-2242347295). - When enabling `HAVE_OBSENSOR_ORBBEC_SDK`, the build now fetches version 2 of the OrbbecSDK, and the sample API calls have been updated to the v2 format. ### Testing | OS | Compiler | Camera | Result | |:----------:|:---------------------------------------:|:-----------------:|:------:| | Windows 11 | (VS2022) MSVC runtime library version 14.40 | Gemini 335/336L | Pass | | Windows 11 | (VS2022) MSVC runtime library version 14.19 | Gemini 335/336L | Pass | | Ubuntu22.04| GCC 11.4 | Gemini 335/336L | Pass | | Ubuntu18.04| GCC 7.5 | Gemini 335/336L | Pass | ### Acknowledgements Thank you to the OpenCV team for the continuous support and for creating such a robust open source project. I appreciate the valuable feedback from the community and reviewers, which has helped improve the quality of this contribution!	1 年前

dnn	Merge pull request #27363 from MRo47:openvino-npu-support Feature: Add OpenVINO NPU support #27363 ## Why - OpenVINO now supports inference on integrated NPU devices in intel's Core Ultra series processors. - Sometimes as fast as GPU, but should use considerably less power. ## How - The NPU plugin is now available as "NPU" in openvino `ov::Core::get_available_devices()`. - Removed the guards and checks for NPU in available targets for Inference Engine backend. ## Test example ### Pre-requisites - Intel [Core Ultra series processor](https://www.intel.com/content/www/us/en/products/details/processors/core-ultra/edge.html#tab-blade-1-0) - [Intel NPU driver](https://github.com/intel/linux-npu-driver/releases) - OpenVINO 2023.3.0+ (Tested on 2025.1.0) ### Example ```cpp #include <opencv2/dnn.hpp> #include <iostream> int main(){ cv::dnn::Net net = cv::dnn::readNet("../yolov8s-openvino/yolov8s.xml", "../yolov8s-openvino/yolov8s.bin"); cv::Size net_input_shape = cv::Size(640, 480); std::cout << "Setting backend to DNN_BACKEND_INFERENCE_ENGINE and target to DNN_TARGET_NPU" << std::endl; net.setPreferableBackend(cv::dnn::DNN_BACKEND_INFERENCE_ENGINE); net.setPreferableTarget(cv::dnn::DNN_TARGET_NPU); cv::Mat image(net_input_shape, CV_8UC3); cv::randu(image, cv::Scalar(0, 0, 0), cv::Scalar(255, 255, 255)); cv::Mat blob = cv::dnn::blobFromImage( image, 1, net_input_shape, cv::Scalar(0, 0, 0), true, false, CV_32F); net.setInput(blob); std::cout << "Running forward" << std::endl; cv::Mat result = net.forward(); std::cout << "Output shape: " << result.size << std::endl; // Output shape: 1 x 84 x 6300 } ``` model files [here](https://limewire.com/d/bPgiA#BhUeSTBnMc) docker image used to build opencv: [ghcr.io/mro47/opencv-builder](https://github.com/MRo47/opencv-builder/blob/main/Dockerfile) Closes #26240 ### Pull Request Readiness Checklist See details at https://github.com/opencv/opencv/wiki/How_to_contribute#making-a-good-pull-request - [x] I agree to contribute to the project under Apache 2 License. - [x] To the best of my knowledge, the proposed patch is not based on a code under GPL or another license that is incompatible with OpenCV - [x] The PR is proposed to the proper branch - [x] There is a reference to the original bug report and related work - [ ] There is accuracy test, performance test and test data in opencv_extra repository, if applicable Patch to opencv_extra has the same branch name. - [ ] The feature is well documented and sample code can be built with the project CMake	11 个月前

gpu	Merge pull request #27444 from vtjl10:4.x Fix Typos and Improve Clarity in Documentation #27444 Description: This pull request addresses minor typographical errors and improves the clarity of documentation in several markdown files. Specifically: - Corrected spelling mistakes such as "traslation" to "translation". - Improved phrasing for better readability and understanding. - Added references to specific setter methods in the StereoBM documentation for more detailed guidance. These changes are limited to documentation and do not affect any code functionality.	11 个月前

introduction	Merge pull request #27864 from peters:patch-2 Add OPENCV_FFMPEG_SKIP_LOG_CALLBACK to preserve custom FFmpeg logging #27864 OpenCV’s InternalFFMpegRegister overwrites av_log_set_callback, blocking custom FFmpeg log handlers in statically linked apps. Add `OPENCV_FFMPEG_SKIP_LOG_CALLBACK` to let applications keep their own logging. ### Pull Request Readiness Checklist See details at https://github.com/opencv/opencv/wiki/How_to_contribute#making-a-good-pull-request - [x] I agree to contribute to the project under Apache 2 License. - [x] To the best of my knowledge, the proposed patch is not based on a code under GPL or another license that is incompatible with OpenCV - [x] The PR is proposed to the proper branch - [ ] There is a reference to the original bug report and related work - [ ] There is accuracy test, performance test and test data in opencv_extra repository, if applicable Patch to opencv_extra has the same branch name. - [ ] The feature is well documented and sample code can be built with the project CMake	7 个月前

others	Merge pull request #27396 from abhishek-gola:hdr_bug_fix Fix NaNs in HDR Triangle Weights and Tonemapping and Update LDR Ground Truth in tutorial #27396 The PR closes #27392 Updated the triangle weights to use a small epsilon value instead of zero to prevent NaN issues in HDR processing. Also fixed a float-to-double division issue by explicitly casting double values to float, which was previously producing garbage values and leading to NaNs in tonemapping. The current LDR ground truth image used in the tutorial [ldr.png](https://github.com/opencv/opencv/blob/4.x/doc/tutorials/others/images/ldr.png) was originally generated using TonemapDurand (check this commit https://github.com/opencv/opencv/commit/833f8d16fab5e57c5e800a55fa0fb08c7a31c3b1), which was moved to opencv_contrib a long time ago in this commit: https://github.com/opencv/opencv/commit/742f22c09bd0c27b450f141bc984f280c8cde98e. However, the current Tonemap implementation in OpenCV main only performs normalization and gamma correction, which produces noticeably different results. This PR updates the LDR grouth truth image in tutorial with the result of TonemapDrago, and tutorials to use TonemapDrago as Tonemap gives a darker image.
