The invention presents catadioptric (single-camera) sensors using one or more mirrors to produce rectified stereoscopic images. By combining multiple views (using the mirrors) to form a composite stereo image that is already rectified (i. e. , has scan-line correspondence), the invention aids provision of real-time stereo images by avoiding computational cost and image degradation due to computer-rectification-related resampling when rectifying. The invention specifies the number of mirrors that must be used and the geometric/locational constraints on those mirrors that must be substantially satisfied to obtain rectified stereo images with a single camera. The invention also discloses specific configurational techniques for how the mirrors should be placed to minimize sensor size. The configurational/geometric parameters disclosed enable cost-efficient, compact, and error-tolerant single-camera stereoscopic image sensing system and methods, removing the need for computer-controlled image rectifying steps and allowing for convenient computerized capture, processing, manipulation, storage, and transmission of stereo images.

A surveillance and monitoring system and method for monitoring an area which includes a first imaging system having a wide-angle field of view approximately equal to or greater than the area. The system also includes one or more second imaging systems having adjustable view settings, each of one or more second imaging systems being positioned to view portions of the area and being capable of producing images of the portions with a resolution greater than the first imaging system. The system also includes one or more controls for controlling the adjustable view settings of the one or more second imaging systems so as to obtain high-resolution, magnified images of regions of interest within the area being monitored. The adjustable view settings may include pan, tilt, and zoom settings for adjusting the panning, tilting, and zooming of one or more second imaging systems with respect to the monitored area. In the method, a global image of the area being monitored is sensed with a first imaging system having a field of view approximately equal to or greater than the area, a region of interest is detected within the global image, and one or more detailed images of the region of interest with at least one of one or more second imaging systems are sensed.
