- the housing further comprises means for measuring a pitch angle formed by the optical axis of the lens of the image pickup device as it is projected onto the horizontal plane.
- an inclinometer which measures and indicates the longitudinal inclination angle at the time of image acquisition serves as such means (WO 2008/129168 A1).
- this mobile measuring device merely represents an image capture device, according to which it is still necessary to connect it to a computer or to connect to a computer. This limits their flexibility.
- the mobile Videozentriersystem invention with the features of claim 1 has the advantage that it is a compact, is easy for the optician to handle device in which a computer is integrated.
- a conventional tablet PC which already has an integrated position sensor and at its left and / or right edge via an image capture device, provided on its side facing the subject with an optical attachment, a periscope and in the beam path of the periscope Fernoptik receives.
- the remote optics make it possible to take the image of the subject at a greater distance.
- the location of the image entry into the optical attachment hereinafter referred to as the image entry opening, determines the length of the beam path and is freely selectable.
- video centering For the purpose of obtaining reliable data from the images of the subject's face, video centering requires that the convergence be compensated for by a correction calculation. This is no longer possible if the subject is too short. However, with a longer shooting distance, the video centering PC cameras, usually equipped with a wide-angle lens for short shooting distance, may lose significant detail. This is prevented by the built-in optical path of the periscope remote optics by filling the face of the subject full-frame on the screen and thus on the memory chip.
- the optical attachment is arranged parallel to the upper edge of the tablet PC.
- the image capture device there is also the image capture device, so that the optical attachment is continued from this along the upper edge.
- the optical attachment is guided to the edge of the tablet PC opposite the image capture device. This gives the video centering system a pleasing symmetrical appearance. In addition, this can be extended the beam path of the lens system of the s.
- the optical attachment is detachably connected to the tablet PC. This makes it possible to use different essays.
- the tablet PC without optical attachment in its original state can be more conveniently handled for purposes other than video centering.
- the optical attachment is connected to a cover that can be placed on the tablet PC, at least in the region of the image capture device is translucent.
- an eyepiece is arranged between the image capture device of the tablet PC and this immediately upstream, the second deflecting mirror, which distributes the incoming light beams to a human eye imitated image capture device with a large opening angle.
- a lens system for a near-vision is arranged in the optical attachment between the image capture device of the tablet PC and located after the image entry opening, the first deflection, with the addition of the local situation can be detected.
- the conventional remote measurement situation serves as a basic measurement, which is supplemented by the data of the near detection.
- the inset values determined in the version level are output.
- the image entry opening of the optical attachment is in the plane of the vertical center of the side facing away from the display of the tablet PC.
- the image entry is moved to the vertical center of the tablet PC, wherein the height of the image entry can be arbitrary.
- the centered image entry into the mobile video centering system is advantageous in order to capture the images captured by the optician during capture. Establishing a straight line to the subject, the so-called fixation line, in an easier way.
- the image entry opening of the optical attachment is in its parallel to the display of the tablet PC's level, so that their optical axis is perpendicular to the display plane of the tablet PC's.
- the mobile video centering system must be raised at the subject's eyes.
- the image entry opening is located at the top of the optical attachment, so that the optical axis runs at exactly horizontal top vertically in a plane parallel to the display plane of the tablet PC's level.
- the optical axis of the image entry opening extends at an angle to the display level.
- the viewing direction about 45 ° to the vertical axis and focusing as well as image acquisition at about 40 cm distance to the subject, make it possible for the optician for the first time, with an electronic video centering system in addition to the lens centering in the viewing situation the viewing situation reading nearby, to determine and to provide the eyeglass lens manufacturer.
- FIG. 1 shows a spatial representation of the mobile video centering system
- FIG. 2 shows the basic structure of the optical attachment
- Fig. 3 shows a second embodiment of the mobile video centering system
- Fig. 4 is a plan view of the open optical system of the second
- FIG. 5 is a front view of the open optical system of FIG. 4.
- FIG. 5 is a front view of the open optical system of FIG. 4.
- the mobile video centering system consists of a tablet PC 1 with a display, a camera 2 located on the side facing away from the display in a top right-hand corner viewed by the viewer of the figures, and a camera built-in, not shown position sensor, which gives the operator on the display information about the situation of Videozentriersystems in space.
- a tablet PC with a display
- a camera 2 located on the side facing away from the display in a top right-hand corner viewed by the viewer of the figures
- a camera built-in, not shown position sensor which gives the operator on the display information about the situation of Videozentriersystems in space.
- At the upper edge of the tablet PC is a from its vertical right edge, while the lens of the camera 2 overlapping, extending to its vertical left edge extending optical attachment 3.
- the optical attachment 3 is detachably connected to the tablet PC 1.
- an image entry opening 4 whose optical axis is perpendicular to the plane of the tablet PC.
- Behind the image entry opening 4 is an entrance optics 5 and a first deflection mirror 6.
- a second deflecting mirror 8 and an eyepiece 9 are arranged, with the eyepiece 9 and the second deflecting mirror 8 are located in the optical axis of the camera 2.
- a lens system with a fourfold magnification was selected.
- the operator usually an optician, holds the tablet PC 1 at the level of the eyes of a subject for whose glasses the centering data are to be determined.
- the optician, the vertical center of the Tablet PC 1 and the center of the subject's face form a straight line, the so-called fixation line.
- the operator can align the axis of the entrance optics 5 exactly on the subject's line of sight to make a frontal view of the face.
- the lens system 7 for the remote optics and the eyepiece 9 are designed so that even at a greater distance of the optician from the subject, ie in about 1 m distance, the face of the subject full-frame images on the search screen of the tablet PC. After triggering the camera 2, the image is stored and can be evaluated to determine the centering data. Characterized in that the tablet PC 1 is moved to receive the face of the subject at its eye level, needs to determine the centering no angle of inclination measured and taken into account, since the recording condition of the zero direction is observed by the optician.
