AI Technical Summary

Problems solved by technology

But the wavelengths used by such systems limit the resolution of the system
And they're also extremely susceptible to interference
[0005] Again, various systems including gyroscopes are also available, but quite complex

Embodiment Construction

[0038] The device for measuring the spatial position of an object according to the invention comprises a helmet 1 on which three infrared light emitting diodes 2, 3, 4 are mounted. Wherein the first light-emitting diode 2 is installed on the top of the helmet, and the other two light-emitting diodes 3 and 4 are installed on the bottom edge 7 of the helmet 1, and are spaced about 90° from each other in the circumferential direction.

[0039] A control unit 8 is mounted on the helmet 1 for controlling the LEDs 2, 3, 4. The control unit will be described in detail below.

[0040] A display unit 9 is attached to the helmet 1 in such a manner that an observer (not shown) wearing the helmet 1 can observe an image generated by the display unit 9 . The helmet 1 including the display unit 9 is a so-called HMD device.

[0041] The device according to the invention also comprises two cameras 10 and 11 capable of recording the helmet 1 or the LEDs 2, 3, 4 from different positions. To t...

Abstract

The invention relates to a method for recording the spatial position of an object, comprising the steps of mounting three light sources (2, 3, 4) on the object to form a triangle; switching on the activation of the light sources (2, 3, 4) Step; Under the state that turns on light source (2,3,4), record the step of recording object from first and second position simultaneously; And determine the position of light source (2,3,4) in the recorded image, and according to The position of the light source (2, 3, 4) is used to calculate the judgment step of the orientation of the object.

Description

technical field [0001] The invention relates to a method and a device for measuring the spatial position of an object. Background technique [0002] This approach is especially suitable for head-mounted display (HMD) devices. According to this method, the observer wears a display device which generates an image that the observer can observe. For this purpose, head-mounted display (HMD) devices are constructed in such a way that the viewer either observes only the generated image or the generated image is superimposed with the background (so-called auxiliary reality). It should be emphasized that, for assisted reality, the movement of the observer and / or the orientation of his head is continuously measured and taken into account when generating the image to achieve the greatest possible overlap. [0003] For this purpose, various magnetic-related methods are often employed. Such methods require an accurate (static or dynamic) measurement of the magnetic field and have the ...
