Smart telescope and method for automatically adjusting magnification

Abstract

The invention provides an intelligent telescope, which includes a mirror body, a motor, a light sensor, a visual recognition camera and a processor. The light sensor is used to detect the brightness of the external environment; the visual recognition camera is used to detect the pupil size of the user corresponding to the brightness; The current pupil size is multiplied by the base of the light to calculate the pupil size of the pupil at the brightness reference, and the focal length between the objective lens and the object is obtained according to the pupil size at the brightness reference; the motor adjusts the distance between the objective lens and the object according to the focal length to obtain the user's desired magnification up or down magnification when viewing objects through the eyepiece. The present invention can judge the magnification required by the user and the observed image by referring to the behavior of the pupil and the eyeball, and increase the consideration of the environmental light source to improve the image recognition rate and accurately achieve the magnification required by the user.

Description

technical field [0001] The invention relates to a telescope, in particular to an intelligent telescope with automatic focus and automatic adjustment of magnification. Background technique [0002] A telescope is a tool that assists in the observation of distant objects by collecting electromagnetic waves (such as visible light). Generally, it collects light such as visible light, ultraviolet light (UV) or infrared light (IR), etc., so it is commonly called an optical telescope. After the optical telescope focuses the light, the image can be magnified directly for visual inspection or photography, etc. In terms of physical structure, the types of telescopes include monocular optical telescopes for observing the night sky, distant animals, and fixed on brackets, as well as hand-held binoculars. According to the optical path, it can be divided into reflective telescopes and refracting telescopes. [0003] Generally speaking, the structure of a telescope includes an eyepiece f...

Problems solved by technology

[0004] However, when using commercially available telescopes, whether they are reflective, refracting or hybrid, often the adjustment of the telescope’s magnification is not accurate enough, resulting in blurred images when the magnification is high, and invisible images when the magnification is low. The problem

This not only affects the user's willingness to use, but also wastes a lot of time on the adjustment of the focal length

In addition, when the user adjusts to the desired image, the general telescope only knows the desired image after adjusting the optical parameters such as the focal length and light intensity, and cannot clearly know the magnification. Manually again and again, very inconvenient
