Technical Field The present invention belongs to the field of see-through eyeglasses, in particular to a pair of see-through eyeglasses used for vision enhancement.
Background Technology With the development of science and technology, application of intelligent devices becomes more and more common in people's daily life. Especially, wearable perspective glasses with an enhanced visual function integrating optoelectronics, information processing and image display, artificial intelligence and other high-tech technologies can help drivers correctly identify road scenes and prevent potential dangers when rain, fog or other weather conditions make their vision blurred.
At present, among wearable perspective glasses, Google Glasses are very well known, with a main structure including a camera hanging in front of the glasses, a computer processor on a right side of the frame, and a tiny display mounted on lens. Google Glasses can project data onto the display and show maps, distances and directions, navigation information and other data. However, due to the powerful functions, complex technologies and high cost, it is difficult to popularize Google Glasses commercially.
Shenzhen VisionerTech Co., Ltd proposed a system of intelligent perspective glasses based on video see through (patent ZL201610218731.2), wherein the system including a camera module, an image pretreatment module, an image fusion module and a display module, wherein data processing devices generate virtual digital images through algorithms, the image fusion module is used to fuse the virtual digital images and high-definition video images before outputting to the display module for display, so as to reduce lip-sync errors, improve the imaging quality and enhance the comfort of the wearer.
A pair of military perspective glasses, similar to infrared detectors, was disclosed by Nanjing Lepeng Electronic Technology Co., Ltd in (patent ZL201610218731.2), wherein reflected infrared lights emitted by infrared generator are received by an infrared receiver, so as to effectively make the material appear translucent, and with an image processing system optical images suitable for human eyes can be converted and displayed on a head-mounted display.
A pair of transparent smart glasses was proposed by Shenzhen Institute of Advanced Technology (Patent ZL2015L0602596.7), wherein according to the 3D model of a target object, relative spatial relationship between external calibration and internal structures can be revealed by an image processing module, and such internal images are displayed on an image display module, so that the internal structure of an object can be observed without damaging surfaces and overall structures of the object.
Thus it can be known that in the eyeglass systems of the prior art, images to be seen through by humans'eyes are all shown on a display screen. However, due to the small size of the display screen and the close distance from the human eye, it is difficult for a wearer to see the scene clearly, and the optic nerve is liable to be fatigued when staring at the image from a close distance.
Summary of the invention In order to solve the above problems, the present invention provides a pair of see-through eyeglasses used for vision enhancement, comprising an image display unit, which improves the definition of the scene, and enhances the comfort of the wearer.
