Energy-saving device for automatically positioning face during face recognition of person

Abstract

The invention relates to the technical field of face recognition, and discloses an energy-saving device for automatically positioning a face during face recognition of a person, and the device comprises a housing, a platform is movably connected to the interior of the housing, a guide column is fixedly connected to the lower end of the platform, and a compression spring is fixedly connected to thelower end of the guide column. The lower end of the guide column is movably connected with a moving rod, the left end of the moving rod is movably connected with a power-on block, the right end of the power-on block is fixedly connected with a wire, the left end of the power-on block is movably connected with a power connection block, a worm is movably connected to the upper end of the power connection block and located at the left end of the shell, and the upper end of the worm is engaged with a worm wheel. The face recognition screen gradually faces downwards to reach the face of a person,at the moment, when the person blocks light irradiated to the photosensitive resistor mechanism from the bulb, the current in the external driving source is too small and cannot be driven, and therefore the face recognition screen stops facing the face, and the effect of automatically positioning the face is achieved.

Description

technical field [0001] The invention relates to the technical field of face recognition, in particular to an energy-saving device for automatically locating a face when performing face recognition on a person. Background technique [0002] Face recognition is a kind of biometric identification technology based on human facial feature information. It is an emerging biometric identification technology. It can detect and track faces in the middle of the process, and then perform face recognition on the detected faces. At the same time, it can be non-contact, and the user can also recognize it without contact. It has been used in many places. [0003] However, the current operation of face recognition equipment still has defects that need to be overcome. There are differences in the height of people. For some short and tall people, face recognition is more troublesome. At the same time, face recognition is often used. It is a waste of electricity in the open state, so an energy...
