Handle distorted images in PointCloud Node - #1958
Conversation
📝 WalkthroughWalkthroughPointCloud now compensates perspective and fisheye distortion by caching undistorted rays. Distorted GPU processing falls back to CPU. Initialization applies frame distortion metadata, while output transformation metadata retains the source image transformation. ChangesPoint-cloud distortion compensation
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟠 High · up to The current implementation can discard non-diagonal image transformations before distortion correction, producing incorrect point-cloud coordinates for rotated transformed inputs; merge is not ready until the full transform is preserved or unsupported transforms are rejected and regression-tested.

Inline comments:
In @.github/workflows/main.workflow.yml:
- Around line 21-22: Update the reviewer-triggered authorization logic so
SHOULD_RUN=true requires write, maintain, or admin permission, rather than
relying on review state. Apply this to both affected sites in
.github/workflows/main.workflow.yml (lines 21-22 and 53-56) and
.github/workflows/python-main.yml (lines 22-23 and 71-77), preserving the
existing matrix and precheck behavior after authorization.
In `@include/depthai/properties/ToFProperties.hpp`:
- Around line 67-68: Add version-aware serialization for ToFProperties around
the DEPTHAI_SERIALIZE_EXT definition so readers can decode the
pre-enableUndistortion member layout as well as the current layout without
breaking compatibility. Preserve the existing field order for new data, provide
the legacy decoding path, and add a mixed-version test covering old and new
readers/writers.
In `@src/device/DeviceBase.cpp`:
- Around line 1743-1745: Update DeviceBase::setExternalStrobeEnable to handle
RVC2 devices before invoking setExternalStrobeEnableExposureMaster, ensuring the
overload still selects the exposure master and enables the strobe without
triggering an unsupported RPC. Apply the behavior consistently to the native and
Python overloads and cover both RVC2 and supported-device paths with tests.
In `@src/pipeline/node/DetectionParser.cpp`:
- Around line 152-158: Update the numYoloOutputs fallback in DetectionParser to
count the entries in the available yolo_outputs metadata rather than filtering
Head::outputs names for the "_yolo" substring. Ensure names such as output0 are
counted consistently with the NNArchive contract so valid strides metadata is
accepted.
In `@src/pipeline/node/Sync.cpp`:
- Around line 289-290: Update the timestamp calculation in the warning near Sync
processing to select the clock based on timestampSource: use system_clock for
TimestampSource::SYSTEM and steady_clock for TimestampSource::HOST or
TimestampSource::DEVICE, preserving the existing millisecond diagnostic format.
In `@src/pipeline/node/ToF.cpp`:
- Around line 111-113: Ensure the RVC2 undistortion warning also runs when
standalone ToFBase builds with properties.enableUndistortion enabled, not only
through ToF::postBuildStage(). Add the validation to the ToFBase build path or
reuse a shared validation helper, while preserving the existing logger guard and
warning behavior.

There was a problem hiding this comment.
This implementation is slightly better: it supports compile-time evaluation and avoids allocating a std::string by returning a std::string_view.
constexpr enables compile-time evaluation; it does not guarantee that every call is evaluated at compile time.
[[nodiscard]]
constexpr std::string_view toString(CameraModel model) {
switch (model) {
case CameraModel::Perspective: return "Perspective";
case CameraModel::Fisheye: return "Fisheye";
case CameraModel::Equirectangular: return "Equirectangular";
case CameraModel::RadialDivision: return "RadialDivision";
}
return "Unknown";
}
