Embodiment Construction
[0018] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0019] A portable angle measuring instrument, which includes an inertial navigation system and a small-angle measurement system fixedly installed in the same housing, and the relative positions of the two remain unchanged; the small-angle measurement system includes a laser and a camera or a laser and a PSD position sensor; is a collimated light source;
[0020] The results of the inertial navigation system are output based on the earth coordinate system, and the results of the small-angle measurement system are output based on the angle measurement coordinate system. The conversion relationship between the coordinate system and the angle measurement coordinate system; therefore, the angle measurement results can be converted to the geodetic coordinate system in real time, so as to realize the angle measurement requirements ...

The invention discloses a portable angle measuring instrument and its application, comprising an inertial navigation system and a small angle measuring system fixedly installed in the same casing, the relative positions of the two are unchanged; the small angle measuring system includes a laser and a camera or a laser and a PSD Position sensor; the results of the inertial navigation system are output based on the earth coordinate system, and the results of the small angle measurement system are output based on the angle measurement coordinate system. The earth coordinate system and the angle measurement coordinate system are respectively established and transformed with the equipment coordinate system by means of a three-dimensional turntable. relationship, and then construct the conversion relationship between the geodetic coordinate system and the angle measurement coordinate system; convert the angle measurement results to the geodetic coordinate system in real time. This equipment can be used to detect the angle change of large-sized equipment installation parts, and only one person can complete the test, and the single-point test only takes 1 minute, which can greatly improve the detection efficiency.
Description
technical field [0001] The invention relates to the field of angle measurement, in particular to a portable angle measuring instrument and a using method thereof. Background technique [0002] In the field of precision machining and manufacturing, after the parts are assembled on the workpiece body of the equipment, the measurement of the installation position and angle of the assembled parts is an indispensable step in the process of equipment quality inspection. Usually, the axis of the assembled parts and the axis of the overall structure It needs to be consistent, and the horizontal angle and vertical angle between the two need to meet the tolerance requirements; at the same time, due to the wear and tear of the equipment during use, the angle information between the parts and the equipment body is also very critical data in its later maintenance. There are a large number of angle measuring instruments in the prior art, but for large equipment, such as aircraft, high-spe...
