Abstract

A distance measuring instrument composed of a fixing frame and two devices fixed to two ends for pointing and taking photo individually. This instrument can be used to measure distance for a remote target and calculate target's coordinates. The pointing device is composed of multiple mirrors to direct backward camera of the intelligent device to the pointing location. The photo device can be any intelligent device having photo function including cellular phone or tablet. When pointing to a remote target, photo taken can be used to calculate distance between photo point and the target. Coordinates of the target location can then be estimated.

Description

Distance measuring device

本發明係關於一種距離量測的裝置，特別可使用於量測遠處，不必到點位即可實施之距離量測的方法。 The present invention relates to a distance measuring device, and in particular to a method for measuring distance, which can be carried out without having to go to a point.

一般對遠端距離的量測，大多採遠端已知物體尺寸與望遠鏡中物體大小作比對，來推估距離，如許多高爾夫專用的測距儀，但其解析度很低，另外採雷射測距儀雖可得很準確的距離，但花費很高，且測距有限。 Generally, the measurement of the distal distance is mostly based on comparing the size of the known object at the far end with the size of the object in the telescope to estimate the distance, such as many golf-specific range finder, but the resolution is very low, and the mining is also Although the range finder can obtain a very accurate distance, it is expensive and has limited range.

本發明中應用平行線測量的觀念，以智慧型裝置前後之鏡頭結合固定架內置之反射鏡或菱鏡，構成具一定距離之照準與照相裝置，運用智慧型裝置中電腦運算之功能，就照片上直接作距離的計算，可達遙測之功效。 In the present invention, the concept of parallel line measurement is applied, and the lens of the front and rear of the smart device is combined with the mirror or the mirror built in the fixed frame to form a camera and a camera device with a certain distance, and the function of the computer operation in the smart device is used for the photo. The calculation of the distance directly can achieve the effect of telemetry.

請參閱第1圖及第2圖。智慧型裝置(A)與照準裝置(B)有一定之距離(d)，形成兩平行線，以照準裝置對準目標後，同步照相，則相片上標的物與相片中心點有與裝置相同的距離，經計算相片上畫素距離相當的角度(a)即可算出拍照處與標的物距離(D)，並可由裝置的方向、方位與傾角計算出標的物的空間座標。 Please refer to Figure 1 and Figure 2. Smart device (A) and sighting device (B) have certain The distance (d) forms two parallel lines, and after the aiming device is aimed at the target, the camera is synchronized, and the photo-marked object and the photo center point have the same distance from the device, and the angle of the pixel on the photo is calculated to be equivalent (a) ) The distance between the photographed object and the target object (D) can be calculated, and the spatial coordinates of the target object can be calculated from the direction, orientation and inclination of the device.

平行線量測的原理：d/D=tan a，D=d/tan a Principle of parallel line measurement: d/D=tan a, D=d/tan a
