Embodiment approach

[0165] When the viewer's viewing position is not correct, the offset position and distance of the viewer can be obtained through the depth or image sensor and known screen size, the depth or image sensor position, focal length, pixels and other parameters (for prior art , which will not be repeated in this embodiment), such as Figure 14 Shown is a schematic diagram of a viewer wearing the smart glasses device 610 captured by a depth or image sensor located on the screen 620 in real time, Figure 13 and Figure 14 Medium X L It is the distance from the viewer's left eye 700 to the screen center o, and the distance D from the left eye 700 to the screen L It can be obtained by converting the depth map, or by using an image sensor such as a monocular or binocular camera through known interpupillary distance conversion or triangular geometry calculation.

[0166] According to the position of the viewer (distance X from the viewer's left eye to the screen center o L and the dis...

Abstract

The invention discloses an imaging analysis apparatus, an imaging apparatus, an imaging adjustment device and a method. The imaging analysis apparatus comprises an information processing module, wherein the information processing module is used for receiving position depth information of an imaging lens set and/or an imaging receiver relative to an object, obtaining imaging parameters corresponding to the imaging lens set based on the position depth information and transmitting the obtained imaging parameters. The imaging apparatus comprises the imaging lens set and a lens adjustment module, wherein the imaging lens set is used for imaging to the object and comprises a plurality of sub-areas imaging characteristics of which can be adjusted; and the lens adjustment module is used for receiving the imaging parameters of the imaging lens set output by the imaging analysis apparatus, determining the sub-areas corresponding to the imaging parameters and adjusting the imaging characteristics of the sub-areas. The imaging analysis apparatus, the imaging apparatus, the imaging adjustment device and the method provided by the invention images to the object by imaging lenses the imaging parameters of which can be individually adjusted in each sub-area, can adjust and correct perspective distortion of the object, so that the perspective distortion of object image obtained by users is avoided.

Description

technical field [0001] The invention relates to the field of imaging technology, in particular to an imaging adjustment device and method. Background technique [0002] The Galilean telescope can form an upright virtual image 1030a of the observed object 1030 through a convex lens 1010 and a concave lens 1020, and change the angle between the virtual image and the eye, forming a visual effect of zooming in or pushing away the observed object along the optical axis 1040. By adjusting the focal length of the two lenses and the distance between them, the magnification and focus can be changed, such as Figures 17a-17c shown. [0003] Lenses with fixed focal lengths have been widely used in optical devices such as glasses, telescopes, cameras, and microscopes. By combining lenses with different focal lengths and adjusting the distance between the lenses, the lens group can dynamically adjust the focal length. In addition, such as U.S. patent applications with publication number...
