Abstract
A surveillance system is formed from two video cameras viewing substantially the same region being monitored. One camera provides high temporal resolution, such as a conventional CCTV camera operating at 30 frames per second with 640 pixels per image width. The second camera provides high spatial resolution, such as a linescan sensor with a mechanical scanning assembly, providing 2 images per second with 5120 pixels per image width. The combination of these two cameras provides a video record of the monitored region with simultaneous high spatial resolution and high temporal resolution.
Claims20
A dual-mode surveillance system comprising:
- a first video camera, said first video camera producing a first video record of a first monitored region, said first video record having a high-temporal resolution;
- a second video camera, said second video camera producing a second video record of a second monitored region, said second video record having a high-temporal resolution;
- said second monitored region being substantially coincident with said first monitored region;
A method of acquiring surveillance video, comprising:
- acquiring a high spatial resolution video record of a monitored region;
- acquiring a high temporal resolution video record of said monitored region;
- storing said high spatial resolution video record in a digital memory;
- storing said high temporal resolution video record in a digital memory;
- recalling said high spatial resolution video record from digital memory;
- recalling said high temporal resolution video record from digital memory;
- displaying said high spatial resolution video record;
- and
- displaying said high temporal resolution video record.
A dual-mode surveillance system comprising:
- first camera means for acquiring a high temporal resolution video record of a first monitored region;
- second camera means for acquiring a high spatial resolution video record of a second monitored region, said second monitored region substantially overlapping said first monitored region;
- digital computer means for storing, manipulating, and displaying said high temporal resolution video record and said high spatial resolution video record.
