Drawings
Fig. 1 is a schematic structural diagram of the barefoot outline imaging system of the invention.
Detailed Description
The present invention is further described in detail below with reference to the attached drawings so that those skilled in the art can implement the invention by referring to the description text.
As shown in fig. 1, the barefoot outline imaging system of the present invention includes a transparent bearing plate 2 for barefoot treading and an imaging device 1 disposed on one side of the bearing plate 2 for taking a picture of the barefoot treading area on the bearing plate 2. The bearing plate 2 can be made of a toughened glass plate, can meet the requirement on mechanical strength of treading of a human body, has light transmission characteristics and can meet the photographing requirement of the imaging device 1 (namely a camera).
And a scattering film 4 is laid on the other side of the bearing plate 1. The scattering film 4 is made of a black opaque film, and the film has elasticity and can be attached to the bearing plate 2 when being stepped. Meanwhile, the surface of the film is required to be uneven so as to perform diffuse reflection on incident light. Moreover, the opaque film is selected to prevent the influence of external transmitted light on imaging. In practice, the scattering film 4 may be a dark thin opaque silicone film.
The LED lamp also comprises a light source component which is arranged on the end surface of the bearing plate 2 and irradiates the inside of the bearing plate 2 from the end surface of the bearing plate 2. The light source assembly may be disposed at one end of the bearing plate 2 (for example, the light source 51), or may be disposed at two opposite end surfaces of the bearing plate 2 (i.e., the light source 51 and the light source 52 in fig. 1). When the light source assembly irradiates the end surface of the bearing plate 2, the propagation path of the light in the bearing plate 2 is total reflection, that is, the light is irradiated to the upper side surface or the lower side surface of the bearing plate 2, and is not irradiated due to total reflection. Therefore, the diffuser film 4 is not illuminated by the light emitted from the light source assembly and remains in a dark state. At this time, the imaging device 1 photographs the region of the bearing plate 2, and since no light is incident on the imaging device 1, the image taken by the imaging device 1 is still dark and has no visible outline.
When the present invention is used to obtain the barefoot outline image, the scattering film 4 is stepped by the barefoot 3, so that the scattering film 4 in the barefoot stepped area can be attached to the bearing plate 2. At this time, the light emitted from the light source module into the bearing plate 2 is changed in propagation path by the scattering film 4 attached to the bearing plate 2, specifically, the total reflection propagation is changed into diffuse reflection propagation, that is, due to the unevenness of the scattering film 4, part of the reflected light deviates from the original total reflection condition to form diffuse reflection, so that part of the light can penetrate through the side surface of the bearing plate 2 and enter the imaging device 1. Furthermore, the boundary at which the light is diffusely reflected coincides with the area on the diffusion film 4 that is stepped on by the bare feet, that is, the boundary at which the light is diffusely reflected can be regarded as the outer contour of the bare feet stepping area, and then the boundary at which the imaging device 1 images due to the incidence of the diffusely reflected light is the outer contour of the bare feet at this time, and the bare feet contour can be obtained by the imaging device 1.
In the barefoot outline imaging system, the barefoot outline of the object in a standing state can be obtained, and the barefoot outline is related to the height and the posture of the object, so that the system is greatly helpful for the subsequent analysis of barefoot morphological data.
While embodiments of the invention have been described above, it is not limited to the applications set forth in the description and the embodiments, which are fully applicable in various fields of endeavor to which the invention pertains, and further modifications may readily be made by those skilled in the art, it being understood that the invention is not limited to the details shown and described herein without departing from the general concept defined by the appended claims and their equivalents.
