Detailed Description
Reference will now be made in detail to exemplary embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings and the description to refer to the same or like parts.
Fig. 1 is a schematic diagram of a virtual reality positioning system according to an embodiment of the invention. Fig. 2 is a schematic diagram of a virtual reality positioning apparatus according to an embodiment of the invention. Fig. 3 is a schematic partial cross-sectional view of a virtual reality positioning apparatus according to an embodiment of the invention. Referring to fig. 1 to fig. 3, in the present embodiment, the virtual reality positioning system 10 adopts an optical tracking positioning technology, and a Lighthouse positioning technology is taken as an example, but not limited thereto. In other words, the virtual reality positioning system 10 may also employ Phase Space positioning technology.
Specifically, the virtual reality positioning system 10 includes a first virtual reality positioning device 100 and at least two second virtual reality positioning devices 200 and 210, wherein the first virtual reality positioning device 100 may be a head-mounted display device worn by the user 1, or alternatively, a handle or a tracker worn or held by the user 1, which is illustrated as a head-mounted display device in the present embodiment, but not limited thereto. On the other hand, the number of the second virtual reality positioning devices 200, 210 can be increased according to actual requirements, wherein the second virtual reality positioning devices 200, 210 are disposed on two opposite sides of the first virtual reality positioning device 100, and are located at opposite corners of the space where the user 1 is located, for example.
The first virtual reality positioning device 100 includes a housing 110, a plurality of lenses 120, and a plurality of first optical positioning elements 130, wherein the housing 110 has a plurality of openings 111, and the number of the openings 111, the number of the lenses 120, and the number of the first optical positioning elements 130 are equal to each other. In terms of manufacturing process, the first optical positioning members 130 are aligned with the openings 111, and then the first optical positioning members 130 are installed and positioned in the housing 110. That is, the first optical positioning elements 130 and the openings 111 are disposed in a one-to-one manner. Then, the lenses 120 are respectively installed in the openings 111, so that the first optical positioning elements 130 are respectively aligned with the lenses 120. That is, the first optical positioning elements 130 and the lenses 120 are disposed in a one-to-one manner. Therefore, the manufacturing process of the first virtual reality positioning apparatus 100 is quite convenient for the production line personnel to execute.
Each first optical positioning member 130 overlaps the corresponding lens 120 in a direction parallel to the main optical axis 121 of the lenses 120. Further, the lenses 120 may be convex lenses, such as plano-convex lenses, and the first optical positioning members 130 may be photosensors, such as photo-sensors or cmos active pixel sensors. On the other hand, the second virtual reality positioning devices 200 and 210 respectively include second optical positioning members 201 and 211, and the second optical positioning members 201 and 211 of the second virtual reality positioning devices 200 and 210 are optically coupled to the first optical positioning members 130. For example, the second optical positioning elements 201 and 211 may be light emitters for projecting light to the space where the user 1 is located and scanning at a specific frequency. The first optical positioning members 130 are used for sensing the light emitted by the second optical positioning members 201 and 211, and then calculating the relative positions of the first virtual reality positioning device 100 and the user 1 relative to the first virtual reality positioning device 100 based on the positions of the first optical positioning members 130 and the time information of the light received by each first optical positioning member 130.
In the present embodiment, the field angle 122 of each lens 120 is greater than or equal to 120 degrees and less than or equal to 160 degrees, so that the light receiving angle of the first optical positioning members 130 can be increased to improve the positioning accuracy and the positioning efficiency. On the other hand, since the first optical positioning elements 130 have a larger light receiving angle, the first virtual reality positioning apparatus 100 can reduce the number of the first optical positioning elements 130 and the number of the openings 111 corresponding to the first optical positioning elements 130 on the housing 110, thereby not only improving the integrity of the appearance of the virtual reality positioning apparatus 100, but also reducing the manufacturing cost.
Specifically, if the virtual reality positioning system 10 employs Phase Space positioning technology, the first optical positioning element 130 may be a light emitter, and the second optical positioning elements 201 and 211 may be light sensors.
Referring to fig. 2 and 3, in order to ensure the positioning accuracy, the housing 110 has at least two different surfaces, and the openings 111 are respectively located on the different surfaces. For example, the housing 110 may have a first surface 110a and a second surface 110b connected to each other, and normal vectors of the first surface 110a and the second surface 110b are not parallel to each other. The number of the openings 111 is at least four, and at least one of the openings 111 is required to be located on the first surface 110a, and the other openings 111 are required to be located on the second surface 110b, so as to ensure that the first optical positioning members 130 can sense the light coming from different directions.
In the present embodiment, each of the openings 111 has a first hole 111a and a second hole 111b communicating with each other, and each of the lenses 120 is mounted in the first hole 111a of the corresponding opening 111. The outer diameter D1 of each lens 120 is matched with the inner diameter D2 of the first hole portion 111a of the corresponding hole 111 to prevent the lens 120 from being released from the housing 110. On the other hand, each second hole 111b is connected to the outer surface of the housing 110, and the inner diameter D3 of each second hole 111b is larger than the inner diameter D2 of the corresponding first hole 111a, so as to match the viewing angle 122 of the corresponding lens 120.
Further, the inner diameter D3 of the second hole portion 111b of each hole 111 increases in a direction S1 away from the first hole portion 111a, and the inner wall surface 111bs of the second hole portion 111b may be a slope. On the other hand, the inner wall surface 111as of the first hole portion 111a of each hole 111 is connected to the inner wall surface 111bs of the corresponding second hole portion 111b, and the inner wall surface 111as of the first hole portion 111a may be parallel to the main optical axis 121 of the corresponding lens 120. The edge 123 of each lens 120 is connected to the inner wall surface 111as of the first hole 111a of the corresponding hole 111, and the angle ANG between the edge 123 of each lens 120 and the inner wall surface 111bs of the second hole 111b of the corresponding hole 111 is 60 degrees or more and 80 degrees or less. In other words, the included angle between the main optical axis 121 of each lens 120 and the inner wall surface 111bs of the second hole 111b of the corresponding hole 111 is also equal to or greater than 60 degrees and equal to or less than 80 degrees. Based on the design of the openings 111, the first optical positioning members 130 are ensured to have a larger light receiving angle.
Fig. 4 is a schematic partial cross-sectional view of a virtual reality positioning apparatus according to another embodiment of the invention. Referring to fig. 4, different from the first virtual reality positioning apparatus 100 of the previous embodiment, the lens 120A of the first virtual reality positioning apparatus 100A of the present embodiment is a fresnel lens, and other design principles can refer to the description of the previous embodiment, which is not repeated herein.
In summary, the virtual reality positioning device of the present invention employs a convex lens or a fresnel lens to increase the light receiving angle of the optical sensor, so that the positioning accuracy and the positioning efficiency can be improved. Correspondingly, the virtual reality positioning system adopting the virtual reality positioning device also has good positioning accuracy and positioning efficiency. On the other hand, because the optical sensor has a larger light receiving angle, the virtual reality positioning device can reduce the configuration number of the optical sensor and the number of the openings corresponding to the optical sensor on the shell, thereby not only improving the appearance integrity of the virtual reality positioning device, but also reducing the manufacturing cost.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
