Abstract
The utility model relates to a footprint acquisition instrument. The footprint acquisition instrument comprises a combination footboard, a plane mirror and a shooting device, wherein the combination footboard, the plane mirror and the shooting device are arranged in a box body. The footprint acquisition instrument is characterized in that the combination footboard comprises a light guide plate, light sources and a reflective tape, the reflective tape is arranged on the light guide plate, and the light sources are arranged on the two opposite side faces of the light guide plate. An angle of 30-40 degrees is arranged between the plane mirror and the light guide plate, and the lens axis of the shooting device is parallel to the plane of the light guide plate. According to the footprint acquisition instrument, a negative image is generated according to a sole stress when people tread on and is transferred through the plane mirror, and a footprint image is acquired in the shooting device. The footprint acquisition instrument is simple in structure, convenient to assemble and debug and distinct in image.
Description
Technical field
This utility model relates to a kind of improvement of track acquisition instrument.Sole stress when this track acquisition instrument is only trampled with personnel produces the footprint negative-appearing image, and is simple in structure, makes debugging conveniently, imaging clearly.
Background technology
The track acquisition instrument that uses at present adopts known optical imaging concept to make, and technology is ripe, is widely used.But also Shortcomings part:
Need some strict angular relationships (each other complementary angle relation etc.) on the light path; Need to use some special transparent adhesive tapes; Trample dull and stereotyped hardness because of sole and frequently trample and wear and tear but changes inconvenience; Problems affect like that is to use, the maintenance of track acquisition instrument.
Summary of the invention
This utility model provides a kind of improved footprint instrument for solving the technical problem that exists in the known technology.
The purpose of this utility model adopts following technical scheme to realize:
A kind of track acquisition instrument, described Acquisition Instrument comprises combination pedal, plane mirror and the filming apparatus that is arranged in the casing, it is characterized in that: described combination pedal comprises LGP, light source and light-reflecting adhesive tape, described light-reflecting adhesive tape is arranged on the LGP, and described light source is arranged on two relative sides of LGP; Angle between described plane mirror and the LGP is 30～40 degree, and the camera lens axis of described filming apparatus becomes parallel position relationship with the LGP plane.
Further, the angle between described plane mirror and the combination pedal is 32～38 degree.
1～5 layer of light-reflecting adhesive tape is set on the described LGP, and on the preferred LGP light-reflecting adhesive tape being set is 1～3 layer.
The track acquisition instrument that this utility model provides, combination pedal is wherein combined by LGP, two side light sources and light-reflecting adhesive tape.The thickness of LGP is without specific (special) requirements, only need satisfy the load-bearing that personnel trample and get final product; Light-reflecting adhesive tape is laid immediately on the LGP, need not to fill the dielectric materials such as any transparent adhesive film or binding agent between light-reflecting adhesive tape and the LGP, and the sole stress when only trampling with personnel produces the footprint negative-appearing image; Distribution of light sources is in the LGP both sides; LGP, light source and light-reflecting adhesive tape can be prefabricated into assembly, put into casing, and it is very convenient to make, install and change.
This utility model track acquisition instrument, the angle between plane mirror and the filming apparatus arranges without specific (special) requirements, and the camera lens axis of filming apparatus becomes parallel position relationship with the flat organic glass plane.
The track acquisition instrument that this utility model provides, the sole stress when trampling according to personnel produces negative-appearing image, transmits through the plane mirror light path, obtains footprint image in filming apparatus, and is simple in structure, makes debugging conveniently, imaging clearly.
