Pose Tool 3D

Pose Tool 3D provides a computation engine to derive a camera-to-world pose or object pose from input data. It accepts 3D point sets, optional camera intrinsics, and selects an estimation method. Internally it performs data normalization, correspondence validation, and a chosen solver (Kabsch for 3D-3D alignment, PnP for 3D-2D, or ICP for point-cloud alignment). The engine outputs a 3x3 rotation matrix R, a 3-vector translation t, and optional residuals or pose error metrics. It can also emit a 4x4 homogeneous transform when needed. Conceptually, a pose is the rigid-body transformation that best aligns source points to destination points under the selected model. This tool is useful for engineers and researchers who calibrate sensors, track objects, or align virtual content to real-world coordinates. A unique value proposition is multi-method support, automatic degeneracy checks, and unit-consistent results across different input types. Typical use cases include camera calibration with known 3D-2D correspondences, object pose estimation in robotics, motion capture alignment, and AR/VR content stabilization. Core features include input validation, method selection, optional outlier rejection, and precise output formatting suitable for downstream pipelines. Outputs can be serialized into transformation matrices for integration with robotics middleware or vision stacks.
