Problems solved by technology

However, the problem with this method is that when the optical axis of the shooting device is not perpendicular to the object to be photographed, there will be a deviation between the measured angle value and the actual value, which is difficult for the photographer to identify

Abstract

The invention discloses an on-site part angle measuring device and method; the device comprises a magnetic base and a cylindrical structure arranged on the magnetic base vertically and connected withthe same to form an integral structure. A light transmitting hole which penetrates the cylindrical structure is arranged at the position, close to a connection portion of the cylindrical structure andthe magnetic base, of the lower end of the cylindrical structure. By means of increasing axial distance, the device is easy for recognizing and adjusting angle deviation, deviation of perpendicularity between optical axis of photographing equipment and a photographed object is ensured to be within a small range, errors when related angle of pictures acquired by the photographing equipment is measured through software are ensured within an acceptable range, and convenience is brought to on-site part angle measuring.

Description

technical field [0001] The invention relates to the technical field of mechanical installation and maintenance, in particular to an on-site part angle measuring device and method. Background technique [0002] In some mechanical transmission devices, the installation angle between parts is required to follow certain requirements. In particular, in the engine gear train, there are strict requirements on the installation angles between the transmission gears. [0003] In assembly and maintenance work, it is often necessary to confirm the angle of the above-mentioned parts. In general operations, it is usually judged whether the angle of the part is correct by comparing it with the characteristic parts of the surrounding parts. This method has low effect and poor accuracy. , while tools such as protractors often fail to measure because parts are often not planar and vary in size. [0004] At present, digital cameras and mobile phones are widely used, and the image sensors use...
