| description | The invention discloses a pinhole camera detecting method based on binocular detection, which is characterized in that pinhole cameras hidden in a room can be effectively detect and its accurate position can be determined; based on the feature of the cat-eye effect of the pinhole cameras that the reflected light is returned along the original path and the scattering angle is quite small, and by means of an invisible laser beam, suspicious areas in a room with possible pinhole cameras can be scanned; two CCDs having certain transverse distance are adopted to simultaneously detect the reflectedlight of the suspicious area; the imaging time sequence of two CCDs maintain simultaneous, and after the sequence images of the two CCDS undergo difference and information processing, the difference images with high recognition degree can be obtained, and effective identification can be realized. The invention is advantageous in that as the two images obtained are both active detection images, thedifference between the re |
