the handle unit 2 comprises an operation module 20 and a power module 21; the operation module 20 generates image data from the head data and the hand data from the head-mounted unit 1, and the operation module 20 transmits the image data to the head-mounted unit 1 through the data wire 3; the hand data relates to the spatial position and hand gesture of the hand of the user; the power module 21 supplies electric power to the head-mounted unit 1 through the data wire 3;
the head unit 1 converts the image data into human eye image data for near-eye display.
The embodiment of the invention has simple structure, simplifies the design of the head-mounted equipment, reduces the cost of the VR equipment, improves the comfort level of VR head-mounted, reduces the strict process requirements on the micro display screen and the lens and the sacrifice of other performances in the head-mounted unit 1 caused by the limited volume, thereby improving the display effect and the duration.
In addition, in the embodiment of the invention, the operation module 20 for carrying out main operation work of the whole VR equipment system is arranged on the handle unit 2, and the main power module 21 for supplying power to the whole VR equipment is moved to the handle unit 2, so that the weight and the volume of the head-mounted part are greatly reduced, more weight and volume space is reserved for designing the lens unit and the display unit, the display effect can be greatly improved, the harsh technological requirements of the head-mounted unit 1 on the micro display screen and the lens are reduced, and the head discomfort problem caused by overweight of the head-mounted unit 1 when the head-mounted unit 1 is worn for a long time is avoided.
Illustratively, the head-mounted unit 1 includes a display screen, an optical lens unit, a head camera, and a head motion sensor;
the display screen displays the image data in a pixel set mode; the optical lens unit performs optical conversion on the pixel set, and adjusts the pixel set so that a picture presented by the human eye image data meets the effect of VR near-eye display.
The head camera and the head motion sensor are used for tracking the spatial position and posture of the head of the user and generating head data.
The head-wearing unit 1 sends data such as images collected by devices such as a head camera to the operation module 20 in the handle unit 2, the operation unit processes the data according to the data and combines the hand data sent by the storage unit to generate image data transformed along with the head position and posture and hand position and posture actions of a user of the VR equipment system, the image data is sent to a display screen in the head-wearing unit 1 to be converted into an image picture, and after the image data is processed by the optical lens unit, the image picture which is suitable for the user to watch in a short distance and generates VR immersion feeling is finally generated.
Hand data may be generated in two ways: one is to install a hand motion sensor and an infrared LED with a specific structural pattern on the handle unit 2, the infrared LED pattern is shot by a head camera on the head-mounted unit 1, and the computing module 20 can calculate the gesture and position of the handle unit 2 through a vision+imu fusion algorithm. The other is that a motion sensor and a camera are arranged on the handle unit 2, the handle unit 2 is not dependent on the head-wearing unit 1, and the posture and the spatial position information of the handle unit 2 can be calculated according to a vision and IMU fusion algorithm, namely, the handle unit 2 adopts an active positioning and tracking mode.
The specific generation process of the hand data is as follows:
the head camera recognizes an infrared LED located on the handle unit 2, pattern information formed by the infrared LED is transmitted to the operation module 20, the operation module 20 processes the pattern information and motion sensor information on the handle unit through a vision+imu fusion algorithm, calculates the posture and position of the handle unit 2, and generates the hand data.
When the posture of the handle unit 2 is different, the patterns formed by the infrared LEDs in the image shot by the camera on the head-mounted unit 1 are also different, so that the posture and the position of the handle unit 2 relative to the head-mounted unit 1 can be analyzed, and the head-mounted unit 1 itself can calculate the posture and the spatial position of the head-mounted unit 1 through the vision+imu algorithm, so that the posture and the spatial position of the handle unit 2 can be further calculated.
Illustratively, the handle unit 2 further comprises a hand motion sensor and a hand camera. The specific generation process of the hand data at this time is as follows:
acquiring hand motion information from the hand motion sensor and external information from the hand camera;
the operation module 20 analyzes the hand motion information and the external information by using a vision+imu fusion algorithm to obtain the gesture and position information of the handle unit 2 and generate the hand data.
Illustratively, referring to fig. 2, the handle unit 2 is comprised of a first handle subunit 22 and a second handle subunit 23.
For example, the handle unit 2 may be composed of two handle units: the first handle subunit 22 and the second handle subunit 23 together assume power supply and data analysis functions.
In the case where such a handle unit 2 is split into 2, it is preferable that the first handle subunit 22 and the second handle subunit 23 are connected to the head-mounted unit 1 by wires, respectively. The first handle subunit 22 and the second handle subunit 23 are connected by wires, and the second handle subunit 23 is connected indirectly to the headset. Preferably, the second handle subunit 23 is not connected to the first handle subunit 22 and the head-mounted unit 1, and at this time, the second handle subunit 23 only performs the basic functions of the handle, and no power transmission exists between the second handle subunit 23 and the first handle subunit 22 and the head-mounted unit 1.
The power module 21 and the operation module 20 may be separated into two handle sub-units, or may be placed in one handle sub-unit at the same time, or may be placed in only one handle sub-unit.
Illustratively, the computing module 20 is built into the first handle subunit or the second handle subunit;
the power module 21 is built into the first handle subunit or the second handle subunit.
It should be noted that, in any case, the data wire 3 may function as an electric power transmission function, and may also function as a data communication function, which is responsible for ensuring the transmission of battery power to each unit, and the data communication between each unit. What kind of function the data wire 3 takes depends on whether the handle subunit connected to the data wire 3 contains the power module 21 or the operation module 20, if the handle subunit connected to the data wire 3 contains the power module 21, the data wire 3 needs to take on the power transmission function, and if the handle subunit connected to the data wire 3 contains the operation module 20, the data wire 3 needs to take on the data transmission function.
Compared with the prior art, the split VR device provided by the embodiment of the invention has the advantages that the operation module 20 for bearing the main operation work of the whole VR device system is arranged on the handle unit 2, and the power module 21 for supplying power to the whole VR device is moved to the handle unit 2, so that the weight and the volume of the head-mounted part are greatly reduced, more weight and volume space is reserved for designing the lens unit and the display unit, the display effect is greatly improved, the harsh technological requirements of the head-mounted unit 1 on the micro display screen and the lens are reduced, and the head discomfort problem caused by overweight of the head-mounted unit 1 when the head-mounted unit 1 is worn for a long time is avoided.
