ship NVIDIA CUDA 12.6 runtime pip dependencies (`python/requirements_win_cuda.txt`) since CUDA is linked dynamically on Windows - Fix WebRTC prebuilt packaging and CI workflow across Linux, macOS arm64, and Windows runtime variants (PR #7515) +- Add RealSense depth post-processing filters for RSBagReader playback (issue #6164). - Add `CorrespondenceCheckerBasedOnSourceRotation` to constrain global orientation priors in RANSAC registration (PR #7461) - Use glfwGetMonitorWorkarea for accurate screen size in GetScreenSize, remove unusable_height estimation hack, and subtract window-decoration extents before clamping auto-sized windows (PR #7469) - Upgrade stdgpu third-party library to commit d7c07d0. diff --git a/cpp/open3d/t/io/sensor/realsense/RSBagReader.cpp b/cpp/open3d/t/io/sensor/realsense/RSBagReader.cpp index 9661cb80f8b..ed8d6800dd1 100644 --- a/cpp/open3d/t/io/sensor/realsense/RSBagReader.cpp +++ b/cpp/open3d/t/io/sensor/realsense/RSBagReader.cpp @@ -25,6 +25,70 @@ namespace open3d { namespace t { namespace io { +namespace { + +rs2_option GetPostProcessingOption(const std::string &option_name) { + static const std::unordered_map options = { + {"filter_magnitude", RS2_OPTION_FILTER_MAGNITUDE}, + {"filter_smooth_alpha", RS2_OPTION_FILTER_SMOOTH_ALPHA}, + {"filter_smooth_delta", RS2_OPTION_FILTER_SMOOTH_DELTA}, + {"holes_fill", RS2_OPTION_HOLES_FILL}, + };
