Abstract

Invention relates to the field of optical detection and ranging, strictly to types of detection and recognition of a type of object with using of TV-methods of signals' identification and can be used within creating of burglar alarm systems. The reached technical result is object detection within disturbing signals and signaling organization of their appearance in a mode, decreasing possibility of object misdetection, caused by human factor - operator's fatigue. Method is based on sounding of controlled space volume by scanning impulse laser emission, receipt of optical image signals from the ordered distance, transduction of the received image signals into videosignal, threshold selection for elimination of background image, as well as on the fact, that sounding of space value is carried out with frequency, equal to f1/n, and emissed impulses subsequence is coded by on-off keying with frequency ff/m, f1 and ff are line and frame frequencies accordingly of the used TV method of signals transduction, n and m - natural numbers, fulfilling the terms n≤f1/ff, 2≤m≤ff/2, reveal videosignals, correlated with a code of on-off keying of emissed impulse subsequence, and form alarm signal automatically, and after transduction of videosignals into optical image - brightness twinkle of TV screen is fixed out with the help of operator, with a frequency of on-off keying.
