Abstract
The invention provides a near-eye display device space positioning system. The system comprises a near-eye display device and an observation device. The near-eye display device comprises light emitting devices which are arranged on the top of the near-eye display device. The observation device is arranged on the top of a positioning space, and the main observation direction of the observation device is downward. Compared with the prior art, as the light emitting devices are arranged on the top of the near-eye display device, the probability that test light emitted by the light emitting devices is blocked during use is reduced, and the accuracy and continuity of measurement are increased. As the light emitting devices are arranged on the top of the near-eye display device, the accuracy of horizontal measurement needing accurate measurement is improved by sacrificing the accuracy of vertical measurement not needing accurate measurement. The near-eye display device space positioning system is of great significance to improving the accuracy of space positioning of the near-eye display device and enhancing the practicality.

Specific embodiment
In order to solve the defect that current nearly eye display device space positioning system is easily blocked and far and near measurement error is larger,
The present invention provide one kind be difficult to be blocked, the accurate nearly eye display device space positioning system of far and near measurement position.
In order to be more clearly understood to the technical characteristic of the present invention, purpose and effect, now compare accompanying drawing and describe in detail
The specific embodiment of the present invention.
Fig. 1-Fig. 2 shows the nearly eye display device space positioning system of prior art, including nearly eye display device 10 and sight
Device 15 is examined, nearly eye display device 10 includes the front panel 11 for arranging nearly 10 front end of eye display device, is provided with front panel 11
Multiple light-emitting devices 13.In position fixing process, light-emitting device 13 is to emission infrared light.Finder 15 observes light-emitting device 13
The infrared light of transmitting, and the infrared light image that arrives according to the observation judges the horizontal coordinate of nearly eye display device 10, i.e. x as shown in the figure
Axle and y-axis coordinate.In existing nearly eye display device space positioning system, finder 15 is generally located on nearly eye and shows dress
Put 10 front or front position on the upper side to be easy to catch infrared ray, when the pedestrian of surrounding is from the front of nearly eye display device 10
It is out-of-date to walk, and the light path between nearly eye display device 10 and finder 15 is easily cut off, and causes finder 15 judge
The position of nearly eye display device 10.In terms of another,, when user coordinate is measured, most important data are user for we
In horizontal coordinate x-axis and the position data of y-axis, when user wears nearly eye display device 10 to be moved along y-axis, finder 15
It was observed that infrared dot matrix image become slightly big or diminish, when lattice position is without more significantly changing, at this moment it is difficult to pass through
The y-axis position for carrying out accurate nearly eye display device 10 is calculated, given position causes very big inconvenience.
Fig. 3-Fig. 4 shows that the structure and principle of nearly eye display device space positioning system first embodiment of the invention is shown
It is intended to.The present invention includes nearly eye display device 20 and finder 25, and finder 25 is arranged on the top in located space region,
Including at least one photographic head, its main detection is directed downward.After user wears nearly eye display device 20, finder
25 tops that can be clearly observable nearly eye display device 20.The top of nearly eye display device 20 is provided with fixing device 21,
Fixing device 21 can be headband, and multiple light-emitting devices 23 are provided with fixing device 21, and light-emitting device 23 is preferably infrared point,
Infrared ray can be launched, the infrared ray of its transmitting can be detected by the photographic head of finder 25.
When user wears nearly eye display device 20 to be used, the transmitting infrared ray of light-emitting device 23 is fixed on user head
The finder 25 in top direction observes the position of infrared dot matrix, and according to the nearly eye display device of the position judgment of infrared dot matrix 20
Horizontal position coordinate.As finder 25 is arranged on user crown direction, it is difficult to there is pedestrian or object blocks infrared point
The situation of battle array, makes positioning more continuous and accurate.When finder 25 is arranged on user crown direction, user is in level
When direction x and y-axis are moved, the infrared dot matrix that finder 25 is observed has obvious movement on image, so for judgement
The position of user horizontal direction x-axis and y-axis just becomes very convenient, and comparatively, for user in the vertical direction
Mobile, the image of the infrared dot matrix that finder 25 is observed becomes slightly big or diminishes, and the degree of accuracy of its position measurement is less than x-axis
With the degree of accuracy of y-axis position measurement.As in use, the measurement significance level of user vertical direction position is less than water
Square to position measurement significance level, therefore, the top that light-emitting device 23 is arranged on nearly eye display device 20 can ensure that
Raising needs the degree of accuracy of the horizontal survey of accurate measurement, sacrifices the degree of accuracy of the vertical direction measurement for not needing accurate measurement,
So as to increase the degree of accuracy and practicality of nearly 20 position measurement of eye display device on the whole.The present invention can also utilize fluorescence light
Source has the ability of identification fluorescence as light-emitting device 23, corresponding facilities for observation.
Fig. 3-Fig. 4 shows the second embodiment schematic diagram of nearly eye display device space positioning system of the invention.The present invention
Second embodiment is essentially identical with first embodiment, and difference is that the top of nearly eye display device 30 is provided with closed
The helmet 34, offer on the helmet 34 several opening 36.In use, the infrared camera with infrared detection function
(not shown) shoots the top pattern of nearly eye display device 30, is much smaller than by the part infrared radiation of 34 overlay masking of the helmet and is opened
Infrared radiation at mouth 36, infrared camera can easily recognize opening 36, and judge that nearly eye show as instruction device with opening 36
The attitude and angle information of showing device 30.
Compared with prior art, light-emitting device is arranged on the present invention top of nearly eye display device 20, reduces use
When the test probability that is blocked of light that sends of light-emitting device 23, increased the accuracy and seriality of measurement.By light-emitting device
23 tops for being arranged on nearly eye display device 20, by sacrifice do not need accurate measurement vertical direction measurement degree of accuracy so as to
Improve the degree of accuracy of the horizontal survey for needing accurate measurement.For the raising of the sterically defined degree of accuracy of nearly eye display device
Enhancing with practicality has larger meaning.Can be increased by the setting opening 36 on the helmet 34 and pass through infrared light, structure letter
Folk prescription just, and is conducive to mitigating the weight of whole nearly eye display device 30.
Embodiments of the invention are described above in conjunction with accompanying drawing, but be the invention is not limited in above-mentioned concrete
Embodiment, above-mentioned specific embodiment are only schematic, rather than restricted, one of ordinary skill in the art
Under the enlightenment of the present invention, in the case of without departing from present inventive concept and scope of the claimed protection, can also make a lot
Form, these are belonged within the protection of the present invention.
