Multifunctional smart cat-eye system

Abstract

The invention discloses a multifunctional smart cat-eye system. A light intensity analysis module is used for comparing a change curve of environmental light intensity data with a preset threshold curve, and a camera is activated when the change curve exceeds the preset threshold curve. A wide-angle optical anti-shake automatic rotation camera is adopted, and an external unit processor is used for controlling the power-on state of an electromagnetic coil (6) in order to rotate a lens. An electromagnetic coil power-on driving module is used for generating a corresponding electromagnetic coil power-on driving signal according to shooting target direction information, so that the aim of automatically rotating the lens according to a shooting target direction is fulfilled. Through adoption of the multifunctional smart cat-eye system, active focusing and capturing can be performed, and a physical rotation angle being 3 degrees is provided. A wide-angle convex lens is adopted, and an actual effective acquisition range is up to 170 degrees, so that a target image can be acquired effectively and completely. In conjunction with judgments on the changing situation of the light intensity and a target distance, the camera is activated when the light intensity drops suddenly and the target distance is relatively small, so that error judgments caused by turn-off of passage lights (the light intensity drops suddenly) and the like are avoided; the judgment accuracy is increased; and the judgment reliability is enhanced.

Description

technical field [0001] The invention relates to an electronic cat's eye, in particular to a multifunctional intelligent cat's eye system. Background technique [0002] The traditional cat's eye uses optical imaging, which is inconvenient in actual use. For example, the viewing angle is not large enough, and the viewing range is limited. You have to get close to the door to see what's going on outside the door. It cannot be used without lights in the corridor at night. The eyesight of the elderly is poor, and the children are not tall enough, so it is not convenient for them to use. In addition to inconvenience, the more important thing is that there are potential safety hazards: cat-eye peepers have appeared on the market, through which criminals can clearly see the indoor situation from outside the door. crime facilitated. We often see related reports from the media: Criminals found no one in the house, removed the peephole, and used tools to reach into the door to ope...
