Embodiment Construction

[0035] Measure the angle with a high-precision compass rotation method.

[0036] Take an angle photo with the camera, print it on A4 paper, and put the A4 paper on a flat surface.

[0037] On the A4 paper plane, use a high-precision compass to make an unknown angle ∠AOB, O point, and a high-precision compass to make an arbitrary circle.

[0038] Take the circle O of step (1), the radius of AB, the point B, the high-precision compass continuously rotates on the circle O, the compass measures 10 circles, and the last point B 10 , the remaining B 10 B.

[0039] The high-precision compass rotates on the circle O 7 times in a row.

[0040] Take B of step (2) 10 B radius, B point, the high-precision compass continuously rotates on the circle O, the compass measures 7 circles, and the last point C 7 , the remaining C 7 B. ​​

[0041] The high-precision compass rotates on circle O continuously 8 times.

[0042] Take C of step (3) 7 B radius, B point, the high-precision compas...

Abstract

The invention provides a method for rotatably measuring degrees of an angle by a high-precision compass, in particular, the method comprises the steps of: taking an angle photograph by using a camera, printing the angle photograph on A4 paper, drawing an arbitrary circle by the high-precision compass, continuously rotating the high-precision compass for k1 times on the circle O, continuously rotating the high-precision compass for k2 times on the circle O, continuously rotating the high-precision compass for k3 times on the circle O and continuously rotating the high-precision compass for k4 times on the circle O. According to the invention, the degrees of the angle are rotatably measured by the high-precision compass, formula and numerical values with ten thousandth precision are determined, and the precise value of the angle is obtained so that the problem of unsuitability for quickly and accurately measuring angle degrees currently is solved.

Description

technical field [0001] The invention relates to an angle method for measuring angles with a compass, which belongs to the field of surveying and mapping engineering. Background technique [0002] Generally, a protractor can only accurately measure the digit of "degree". The measurement accuracy of the universal angle ruler is 2′, and the accuracy is still less than one hundredth of a degree. [0003] Therefore, improving the accuracy of angle measurement is a long-standing problem to be solved by those skilled in the art, and eagerly hopes to have a method for fast and accurate measurement of angle: the method of measuring angle with high-precision compass rotation, and the method of measuring angle with compass rotation to quickly obtain the accurate degree of angle technology has not yet been reported. Contents of the invention [0004] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a high-precision compa...
