Under vehicle examination and novel applications of digital storage techniques

In September 1991 the Home Office Police Scientific Development Branch was approached by the Directorate of Special and Central Services to undertake a study to determine if a "real-time" undercar viewing facility could be designed and developed for use at a central London location. Investigations were undertaken which resulted in PSDB being contracted to develop and prove the capabilities of such a system. Designed to a high specification the viewing facility, known as Fisheye, uses a gated CCD imager linked to an IBM PC based computer terminal. It has been designed to supplement an established manual search procedure for the inspection of the underside of passenger vehicles entering a secure area, prior to proceeding to an underground car park.
