Abstract
This disclosure relates generally to video analysis, and more particularly to systems and methods for mapping object co-ordinates from a video frame view to real world co-ordinates using perspective transformation. In one embodiment, a processor-implemented video frame coordinate transformation method is disclosed. The method may include obtaining an image from an image capture device and identifying, via one or more hardware processors, an object depicted in the image. Further, the method may include determining image-frame object coordinates for the object, and selecting one of a plurality of coordinate transformation matrices associated with the image capture device, based on the image-frame object coordinates for the object. Also, the method may include calculating, via the one or more hardware processors, real-world object coordinates for the object using the image-frame coordinates and the selected coordinate transformation matrix, and determining a trajectory of the object using the calculated real-world object coordinates.
