Data Mining Method and System For Estimating Relative 3D Velocity and Acceleration Projection Functions Based on 2D Motions
First Claim
1. A method for transforming data from a first image of a space to a second image of the space, the method comprising:
- receiving image data from a video camera monitoring the space, wherein the video camera generates image data of an object moving through the space;
determining spatio-temporal locations of the object with respect to a field of view of the camera from the image data;
determining observed attributes of motion of the object in relation to the field of view of the camera based on the spatio-temporal locations of the object, the observed attributes including at least one of a velocity of the object with respect to the field of view of the camera and an acceleration of the object with respect to the field of view of the camera; and
determining the transformation matrix based on the observed attributes of the motion of the object.

Abstract
A method for determining a transformation matrix used to transform data from a first image of a space to a second image of the space is disclosed. The method comprises receiving image data from a video camera monitoring the space, wherein the video camera generates image data of an object moving through the space and determining spatio-temporal locations of the object with respect to a field of view of the camera from the image data. The method further comprises determining observed attributes of motion of the object in relation to the field of view of the camera based on the spatio-temporal locations of the object, the observed attributes including at least one of a velocity of the object with respect to the field of view of the camera and an acceleration of the object with respect to the field of view of the camera. The method also includes determining the transformation matrix based on the observed attributes of the motion of the object.
