Definitions
- the invention relates to devices for measuring surface contours and can be used in a security system to identify a person.
- a device for contactless control of the surface profile of objects including a backlight unit with a light source and a banner, forming an image of a banner on the surface of the object and an image registration unit.
- the disadvantage of this device is its inability for biometric control of the face profile, since it involves arbitrary orientation of the face, which requires the binding of points on the face profile to its image and complicates biometric control of the face surface.
- a device for biometric control of a face surface is known, WO 02/09038 of 01/31/2002, including a camera (image registration unit), a face position indication unit and a calculator.
- the disadvantage of this device is the low accuracy of measuring the position of points on the surface of the face, due to the determination of their coordinates only on the plane, and not in space, and low efficiency in conducting biometric control, due to the need for manual operations. Disclosure of invention
- the invention is aimed at providing operational biometric control of the face surface.
- the technical result of using the invention is to increase the efficiency of control and accuracy in determining the biometric features of the face.
- a device for biometric control of the surface of the face including a camera, a unit for indicating the position of the face and a computer. Additionally, this device includes a backlight unit with a banner and a lens projecting a banner image onto the face surface, mounted so that the optical axis of the lenses of the backlight unit and the camera lie in the same plane at an angle to each other, and the face position indication unit is made and installed with the possibility of indication the symmetrical position of the face relative to the plane formed by the optical axes of the lenses of the backlight unit and the camera.
- the calculator binds the face surface profiles obtained by it to the coordinate system associated with the person’s face.
- the calculator is configured to determine the actual, asymmetric position of the face relative to the plane formed by the optical axes of the lenses of the backlight unit and the camera.
- the lenses of the backlight unit and the camera can be located one below the other so that their optical axes lie in a vertical plane, and the face position indicator is located between them.
- the transparency of the backlight unit can be made in the form of a raster of parallel segments of strips and one transverse strip to them along the axis of symmetry of the raster and set so that its transverse strip is located in a vertical plane formed by the optical axes of the lenses of the backlight unit and the camera.
- the face position indicating unit may be made in the form of a flat mirror with a strip mounted so that the strip is in a plane formed by the optical axes of the lenses of the backlight unit and the television camera.
- the face position indication unit can be made in the form of a two-sided mirror or in the form of several two-sided mirrors, the edges of which are located in the plane formed by the optical axes of the lenses of the backlight unit and the television camera.
- the face position indication unit can be made in the form of a television screen with vertical marking that determines the position of the plane formed by the optical axes of the lenses of the backlight unit and the television camera.
- FIG. 1 shows a diagram of a device for biometric control of a face surface.
- FIG. 2 schematically shows the location of the device blocks, as they are visible to a person with biometric control of his face.
- FIG. 4 and FIG. 5 schematically shows a composite mirror block indicating the position of the face.
- the device includes a backlight unit 1 with a banner and a lens projecting a banner image onto the face, a camera 2, a calculator 3, and a face position indicator 4.
- the optical axis of the projection lens of the backlight unit 1 and the lens of the camera 2 are located at an angle ⁇ to each other. Distorted by the profile of the surface of a person’s face, the image of the banner is recorded by a television camera and transmitted to calculator 3, which calculates the height Z of the surface profile for a point with coordinates X, Y according to the formula:
- the calculator determines the characteristic points and areas of the face surface in three coordinates.
- the person whose face is being examined is orienting his face, as shown in FIG. 2, using the face position indicator 4, which can be made in the form of a mirror or a television screen with vertical markings, which allows you to orient the nose along the markings or eyes - symmetrically with respect to the markings.
- the display unit can be made in the form of a two-sided mirror or a set of two-sided mirrors (see Fig. 3, Fig. 4 and Fig. 5), the edges of which are located in the plane formed by the optical axes of the lenses of the backlight unit and the television camera.
- the implementation of the transparency of the backlight unit 1 in the form of a line raster with a transverse strip located in a plane formed by the optical axes of the lenses of the backlight unit and the camera, allows a person to orient the face symmetrically with respect to this transverse strip, observing it in the face position indication unit.
- the nose is located along it.
- the backlight unit and the camera can operate outside the visible part of the optical range.
- the calculator is configured to determine the actual, asymmetric position of the face relative to the plane formed by the optical axes of the lenses of the backlight unit and the camera.
