Creates an oriented bounding box using a PCA. Note that this is only an approximation to the minimum oriented bounding box that could be computed for example with O’Rourke’s algorithm (cf. http://cs.smith.edu/~jorourke/Papers/MinVolBox.pdf, https://www.geometrictools.com/Documentation/MinimumVolumeBox.pdf) This is a wrapper for a CPU implementation.
- Parameters:
points (open3d.core.Tensor) – A list of points with data type of float32 or float64 (N x 3 tensor, where N must be larger than 3).
robust (bool, optional) –
If set to true uses a more robust method which works in degenerate cases but introduces noise to the points coordinates. Default value:
