Abstract

An image processing sensor system functions as a standalone unit to capture images and process the resulting signals to detect objects or events of interest. The processing significantly improves selectivity and specificity of detection objects and events.

Claims

1. A system comprising:

means for selecting an object of interest;

means located on a first processing station for collecting images containing the object of interest and transforming image representations of the object of interest into a single results key with data targeting a particular object of interest or event sufficiently to provide a threshold level of confidence in detecting the particular object of interest or event;

an image capture and processing device that is remote from the first processing station and operable to capture images,

the image capture and processing device being programmed with an analysis algorithm to process the captured images;

means for transferring the results key to the image capture and processing device;

the results key configuring the analysis algorithm of the image capture and processing device for analysis of the captured images to detect the object of interest; and

the image capture and processing device including self-contained means for analyzing the images in cooperation with the results key, and for conditionally providing an output signal based on the results of said analysis to drive a secondary system for action appropriate to detection of the object of interest when if one or more selected characteristics of the object of interest are present in the sample image,

wherein the results key is dedicated to a single object of interest, and

the image capture and processing device is configured to operate on a standalone basis without further exchanging data with the first processing station as the image capture and processing device repeatedly uses the results key to analyze sample images for the presence of the object of interest.

2. The system of claim 1, wherein the means for transferring the results key includes a portable memory component.

3. The system of claim 1, wherein the means for transferring the results key includes circuitry configured to receive a wireless transmission.

4. The system of claim 1, wherein the means for transferring the results key includes a cable interconnect.

5. The system of claim 1, wherein the image capture and processing device further includes one or more property sensors.

6. The system claim 1, wherein the image capture and processing device further includes a real time clock function.

7. The system of claim 1, wherein the image capture and processing device further includes GPS.

8. The system of claim 1, wherein the image capture and processing device includes an artificial electromagnetic energy source that improves the capability to capture an image in the field of view.

9. The system of claim 1, further comprising a mechanism that is selectively actuable through use of a control output signal conditioned upon a result of said analysis.

10. The system of claim 1, further comprising means for providing one or more output signals conditioned upon a result of said analysis, and for using a plurality of results keys sequentially during a course of said analysis.

11. The system of claim 1, further comprising means for preventing spoofing of the system.

12. The system of claim 1, wherein the image processing and capture device contains a lens that has a total field of view and analysis algorithm performs the analysis using a selected portion less than the total field of view.

13. The system of claim 1, wherein the image processing and capture device contains a lens that has a field of view equal to or greater than 180°

.

14. The system of claim 13, wherein the lens has a 360°

field of view.

15. The system of claim 1, including an integrally housed electromagnetic radiation source configured for selective activation based upon a threshold analysis that improves selectivity of said analysis.

16. The system of claim 1, further comprising means for providing an output control signal based upon observed interaction over time between a plurality of discrete objects of interests.

17. The system of claim 1, further comprising means for increasing a system sampling rate based upon a detected event.

18. The system of claim 1, further comprising means for making an improved results key available to the image capture and processing device at a future time, where the improved results key provides a higher degree of specificity of the object of interest.
