A system and method for combining images generated by separate sources. The system comprises a plurality of video image data sources that generate separate video images. The video images are captured and scaled by image processing hardware to fit within the viewports of a target window generated by a computing device. The parameters of the viewports are associated with the parameters of the target window such that changes to the target window result in corresponding changes to the viewports. The method comprises scaling the separate images to fit within the viewports using redundant data within each video image to interpolate pixel data at the boundary regions of adjacent images to eliminate artifacts at the boundary regions.

A synoptic, broad-area remote-sensing system using multiple sensors mounted on an airborne platform. Commercially available optical telescopes can be used as the sensors and can be mounted to the platform with fixed location and orientation to collectively view a wide strip of land. Each telescope views a generally linear coverage area which overlaps an adjacent coverage area of another telescope. The images from the coverage areas of the multiple telescopes are stitched in electronic image processing into continuous strips of high-acuity image data. Calibration, distortion correction, alignment and the like are carried out in the electronic image processing using proven, commercially available hardware and software. The image detection for each telescope can be implemented using a linear arrangement of multiple, overlapping linear detectors to yield a wide, high-acuity, virtual field-of-view. The linear detectors can be commercially available detectors with multi-spectral capabilities. A system with large-area synoptic coverage can thus be implemented using low cost, commodity optics and detectors in combination with commercially available image processing hardware and software.

This process and invention may be used for “live” (on-line, recorded, real-time, or transmitted) stereoscopic image generation, post-production, and viewing to ensure the imagery, from the cameras through the systems to the final screens, maintains an acceptable level of viewer comfort and actively causes an action if an image becomes “uncomfortable” to view. The invention will use image-processing hardware and software to monitor stereoscopic 3D image data, and will generate an output response based on qualifying the imagery. The output responses include generating an alarm to alert technical crew members to a “discomfort” condition so they may take corrective action. The alarm may be an audio or visual alert, and warn of the type of discomfort detected. The alarm condition may trigger the automatic control of a video switching device, which would immediately route an appropriate “comfortable” input source to the output. The alarm condition may duplex a single camera or playback signal into an identical stereo pair, which will be 2D, but will be comfortable to view.
