Golf course hole distance measuring apparatus using split prism

Abstract

PURPOSE: A distance meter for a golf course hole using an image separation prism is provided to precisely measure a distance to a flagpole despite the generation of vibration such as hand tremor. CONSTITUTION: A distance meter for a golf course hole using an image separation prism includes a barrel-shaped housing (110), an objective lens (140), an indicating unit, the image separation prism (140), and a distance indicating part (150). The front and the rear side of the housing are opened. The objective lens is formed with at least one lens at the front end of the housing, and the lens faces a target. The distance indicating part provides an image at the objective lens to a user. The prism between the objective lens and the indicating unit separates the image at the objective lens, and then forms the image. The prism inside the housing moves in an optical axis in order to control a distance between the separated images. When the position of the prism is controlled so that the distance between the separated images is set on a referential position, the distance indicating part indicates a distance to the target according to the position of the prism.

Description

technical field [0001] The present invention relates to a distance finder for a golf course hole using an image segmentation prism, and in more detail to a golf ball distance measuring instrument that uses a telescope to easily and accurately detect the distance to a distance measuring object such as a flagpole or a flag in a golf hole. rangefinder. Background technique [0002] Generally speaking, the game rule of golf is that after the player confirms the distance of the hole, he uses a golf club that meets his own hitting distance to hit the ball into the hole with the least number of strokes. [0003] At this time, in order to make it easier for players to check the distance and direction of the hole, a flagpole with a height of about 2.2m is erected on the hole. [0004] Therefore, the Korean Utility Model Publication (Gazette No. 91-2959, Utility Model Name: Golf Flagpole Rangefinder) discloses a technique for measuring distance using a general flagpole height, which ...

AI Technical Summary

Problems solved by technology

Therefore, the farther the distance is, the tighter the scale will be. If it is measured against a flagpole that appears smaller at a long distance, serious errors will occur, and even the problem of being impossible to measure

[0007] In order to solve this problem, it is also possible to use the figure 1 The telescope shown is composed of a reticle 40 engraved with the scale and reference line number of the above-mentioned conventional structure, but depending on the magnification of the telescope, the image reacts sensitively to movements such as hand shaking, so it is difficult to confirm whether it is related to the flagpole. Scale corresponding to the size

[0008] That is, in the case of applying a telescope as in Korean Patent Application Laid-Open No. 10-2001-0084094, image shake due to hand shake or body motion increases in proportion to the magnification of the telescope, and therefore, it is not easy to The scale is confirmed by aligning the image with the scale on the fixed scale plate, which leads to a decrease in distance measurement accuracy, inconvenience in use, and a decrease in the use rate.

[0009] On the other hand, the laser distance measuring device that emits laser light to the flagpole and uses the reflected light to measure the distance has the advantages of high precision, but has the disadvantage of being expensive; using GPS devices, measuring the center or edge of the player and the green (green) The distance measuring device using GPS is a device for estimating the precise distance from the flagpole, which has the inconvenience of requiring continuous upgrades
