1. A processor-implemented video frame coordinate transformation method, comprising: obtaining an image from an image capture device; identifying, via one or more hardware processors, an object depicted in the image; determining, via the one or more hardware processors, image-frame object coordinates for the object; selecting, via the one or more hardware processors, one of a plurality of coordinate transformation matrices associated with the image capture device, based on the image-frame object coordinates for the object; 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; determining, via the one or more hardware processors, a trajectory of the object using the calculated real-world object coordinates; determining, via the one or more hardware processors, that a position on a map of a site in which the image capture device is located is not included in any trajectory of any object for a predetermined period of time; and classifying, via the one or more hardware processors, the position on the map as a blind spot.
