An electronic apparatus and method for sequence stabilization of point cloud frames using motion information is disclosed. The electronic apparatus receives image data that includes images of objects. The image data corresponds to a duration in which in the objects are in a dynamic state. Based on the image data, the electronic apparatus generates a point cloud sequence and extracts motion information associated with the objects. The electronic apparatus determines a first set of 3D points of a first point cloud frame that is in a static state with respect to a second set of 3D points of a second point cloud frame, based on the motion information. The first and second point cloud frames are consecutive frames of point cloud sequence. The electronic apparatus further determines a difference between the first and the second set of 3D points and updates the first point cloud frame based on the difference.

Sequence stabilization of 3D point cloud frames using motion information

Images from the video camera of a computer are compared over time, e.g., every few milliseconds, to determine from the pixel data if motion of the computer matches template motion associated with an earthquake P-wave. If so, a warning is generated, uploaded to a communication network, and propagated over the network to other computers.
