Compact Vandal-Proof Video Camera on the Basis of Multimatrix Receiving System for Security of Premises
Abstract
Introduction: To solve a number of problems, special requirements are made on video surveillance systems: an increased field of view combined with high resolution and, at the same time, small dimensions and low power consumption (in order to impede their detection). Purpose: To design a compact vandal-proof video camera with a reduced heat emission for observing extended objects. Results: A constructive solution is proposed for a video camera. The idea is to replace a large-format CCD matrix by three small-size matrices compactly arranged inside a small camera in such a way that they display only useful information. An important role in this solution is given to the optical system. Its parameters have been calculated, and an optical layout is given for the pinhole lens. A light beam behind the lens creating a complete image of the guarded object is split into three for the three CCD-matrices using flat mirrors. Special software merges the fragments of the object image formed by separate matrices so that the resulting single image fits the observed object. In this form, the image is broadcast on the monitor. Practical relevance: Schematic and design solutions based on a single pinhole lens and a receiver consisting of three small CCDs composed along the direction of interest can provide a small and difficult-to-detect video camera for observing an extended guarded object.Published
