Estimating the term…
A scene to be monitored (e.g., at a remote location or at a later time) is captured as a series of still images. These images are digitally encoded and stored in a digital memory for subsequent retrieval and viewing. If the scene includes a moving object (e.g., the side of a moving freight train), the images may be taken so that they are substantially mutually exclusive and collectively exhaustive of the moving object. During playback, two or more adjacent images may be displayed adjacent to one another so that any feature partly present in adjacent images is visible as a whole. If the observer is at a location remote from the point at which the images are taken, various techniques can be used to facilitate transmission of the image information (preferably in digital form) via relatively low-cost transmission links such as voice-grade telephone lines.
Apparatus for remote observation of objects comprising:
Apparatus for remote observation of objects which are the sides of freight cars in a moving freight train comprising:
Apparatus for remote observation of objects which are the sides of freight cars in a moving freight train comprising:
The method of monitoring a scene in the field of view of a video camera, said scene changing over time, and said video camera producing a video output signal representative of successive images of said scene, said method comprising the steps of:
Apparatus for monitoring a scene in the field of view of a video camera, said scene changing over time, and said video camera producing a video output signal representative of said scene, said apparatus comprising:
The method of monitoring a scene represented by a succession of still images stored in digital data form in a digital memory, said scene including an object moving relative to the vantage point from which said images are taken i a direction parallel to the plane of said images, said object being larger parallel to said direction of motion than the field of view of any one image, and wherein a portion of a feature of the object to be monitored may be in one image and another portion of said feature may be in the next sequential image, said method comprising the steps of:
