Camera perspective method and device

Abstract

The invention discloses a camera see-through method and device, wherein the camera see-through method includes: acquiring the camera viewing angle, the viewing angle of the human eye relative to the screen, and the positional relationship between the human eye and the camera; information, the positional relationship between the human eye and the camera, and the field of view of the human eye and the camera, calculate the cropping ratio of the camera image and the display ratio of the screen; intercept the camera image according to the cropping ratio and camera resolution of the camera image , and interpolate the captured camera image according to the display ratio and screen resolution of the screen to generate a perspective image and display it on the screen. According to the camera perspective method and device provided by the embodiments of the present invention, according to the positional relationship between the human eye and the camera, the corresponding camera image interception ratio and screen display ratio are calculated for perspective objects at different positions, so as to intercept and interpolate the camera image , so that the screen can display a camera image that matches the field of view of the human eye.

Description

technical field

[0001] The invention relates to the technical field of perspective, in particular to a camera perspective method and device. Background technique

[0002] See through technology (see through, ST for short) mainly includes two types, one is camera-based see through technology (video see through, VST for short), and the other is optical see through technology (optical see through, OST for short). VST uses the camera to obtain the external scene, and images the external scene on the screen according to the projection relationship, bringing users the depth perception of the real scene. OST allows the human eye to directly observe the external scene through optical perspective. Limited by equipment, OST has a small field of view of external scenes, generally no more than 40°. Such a small field of view limits the application of OST. The existing VST can be applied to smart glasses. After collecting images of external real scenes through the camera, the images ar...
