Detailed Description
First, related art terms involved in the embodiments of the present disclosure are briefly described.
1. HoloLens intelligent glasses
The HoloLens intelligent glasses can realize the mixed reality function and adopt an integrated machine body.
Firstly, the HoloLens intelligent glasses can acquire information in a real environment through a camera and other sensors; secondly, rendering a corresponding image by using a specific algorithm through the HoloLens intelligent glasses after the HoloLens intelligent glasses are processed by a processor; finally, the HoloLens smart glasses will render the corresponding image to be displayed on the lens so that the wearer feels that the virtual image coincides with the real world.
It can be understood that the structure of integral type fuselage does not have the wire to connect, and the integration is better, and it is also comparatively convenient to carry. However, in the smart glasses of the integrated type, all the functional modules are disposed at the glasses end, and the core modules such as the processor and the battery are disposed at the glasses end, so that the following problems may occur: 1) the glasses end has heavier weight and larger volume; 2) when the intelligent glasses are operated, the heat generated by the processor easily causes the head-wearing end to be overheated; 3) the volume and the capacity of the battery are limited, so that the endurance time of the whole machine is short.
2. Magic Leap intelligent glasses
Magic Leap smart glasses can realize augmented reality functions similar to HoloLens smart glasses, and a split type machine body is adopted. The main control and the battery of the Magic Leap intelligent glasses are in a separated state. The glasses end (namely, the head-wearing end) of the Magic Leap intelligent glasses is provided with an independent vision processing unit, the processor module is arranged on a separate computing unit, and the glasses end is connected with the computing unit through a lead.
Firstly, preprocessing data acquired by a camera and a sensor at the glasses end of Magic Leap intelligent glasses and then sending the preprocessed data to a computing unit; then, the computing unit renders a corresponding virtual image according to the acquired information and transmits the virtual image to the glasses end; finally, the glasses display the rendered virtual image.
It can be understood that the intelligent glasses adopting the split structure can place the modules such as the processor and the battery in the computing unit (for example, a computing box), so that the glasses end does not have a large heating device, the increase of the battery capacity does not lead to the increase of the volume and the weight of the head-wearing end, and the head-wearing end of the intelligent glasses can be made to be thinner and lighter. Based on this, many manufacturers of smart glasses equipment prefer to develop split smart glasses.
3. Nreal intelligent glasses
The Nreal intelligence glasses are simple split type AR glasses, and the glasses end and the master control (Host) end are connected through a dedicated bridge (bridge Integrated Circuit, bridge IC). The main control, the battery and other components are arranged in an independent computing box and separated from the glasses end (also called as a head display), so that a computing box (Host) is connected with the glasses end (Device) framework. Unlike Magic leap smart glasses, the glasses side of Nreal smart glasses do not have powerful functionality.
Firstly, the glasses end of the Nreal intelligent glasses is responsible for collecting and inputting data and outputting images and sound; the glasses end of the Nreal intelligent glasses sends data collected by the camera and data collected by other sensors to the Host end through a special bridge IC; then, the Host end processes the data sent by the glasses end to generate a corresponding image, and sends the generated image to the glasses end of the Nreal intelligent glasses through a signal line; and finally, the glasses end of the Nreal intelligent glasses displays the image generated by the Host end.
It should be noted that, in the current smart glasses using a split-body main body, all data exchange between the peripheral device (e.g., the glasses side) and the host side (e.g., the main control side) is required through the USB data line.
The embodiment of the present disclosure provides a split type intelligent glasses, which includes: the target USB interface of pluggable connecting wire, two photoelectricity adapters are provided with optic fibre in the data line of intelligent glasses transmission data, adopt optical fiber communication between the mainboard of intelligent glasses and the target USB interface.
