Abstract
Searching through a series of images such as video images for slowly-moving objects such as enemy snipers, using pattern matching, color matching, brightness matching, or the like. Multiple search speeds facilitate finding objects moving at different velocities through the visual field. Search speeds can be determined as, e.g. every Nth frame, or a frame from every Nth period of time. Background motion, such as bushes blowing in the wind, do not trigger false positives.
Claims42
An apparatus comprising:
- an image acquisition system;
- a processor;
- a memory coupled to the processor;
- and, stored in the memory,
- slow motion hunting software, executable by the processor, to identify an object moving slowly through a series of images from the image acquisition system.
A motion detection system for use with an image acquisition device, the system comprising:
- processor means for performing logical operations of the system;
- and
- memory means storing,
- software means for managing a series of images from the image acquisition system, and
- software means for hunting through the series of images for an object moving slowly through a field of vision of the image acquisition device.
A method comprising:
- selecting a first search speed;
- searching, at the selected search speed, a series of images for an object moving slowly through a field of view of the images;
- if the searching at the selected search speed found an object moving slowly through the field, signaling an alarm;
- selecting a next search speed;
- and
- returning to the searching of the series of images with the next search speed.
A method of identifying a slowly-moving enemy, the method comprising:
- capturing a series of visual images of a landscape in which scenery is moving in wind;
- searching through the series of visual images for motion which, over time, progresses over a visual field in a manner inconsistent with being merely wind motion.
