Embodiment Construction

[0017] Below in conjunction with accompanying drawing and specific embodiment the method of the present invention is described in further detail, and whole detection process is as follows:

[0018] 1) The testing equipment is attached figure 1 Placement as shown: First, place the multi-tooth indexing table 1 on the horizontal surface, level the multi-tooth indexing table with an electronic level, place the angle measuring device 2 at the center of the multi-tooth indexing table 1 and fix it with bolts. The detection step can be attached with figure 2 illustrate:

[0019] 2) First turn on the angle measuring device 2, and turn the multi-tooth indexing table 1 so that the angle measuring device 2 outputs a reading to zero. At this time, the connecting line 5 of the two target point light sources 3 and 4 is parallel to the reference line 6, and the scale value of the multi-tooth indexing table 1 and the measured value output by the angle measuring device 2 are recorded at this...

Abstract

The invention relates to a detecting method for measurement accuracy of an angle measuring equipment, belonging to the field of optical apparatus detection. The angle measuring apparatus can get the angle value between the link of the two target points and the reference line azimuth and two pitching directions by adopting optical imaging and calculation. The invention aims at detecting the accuracy of the angle value, the detection mainly adopts the equipment such as a multiteeth indexing table and an electronic level meter; firstly, the electronic level meter is used for leveling the multiteeth indexing table, then the angle measuring equipment is placed at the center of the multiteeth indexing table and is fixed by a bolt, the multiteeth indexing table is rotated for a certain angle, the scale is taken as a true value, at the same time the output measurement value of the angle measuring apparatus is recorded, after repeated measurements the detecting accuracy of the azimuth direction of the angle measuring apparatus can be obtained; then the angle measuring apparatus is rotated for 90 degrees and the above steps are repeated to obtain the pitching direction of the angle measuring apparatus. The detection process of the invention is simple and effective, the price of the apparatus is low, the movement is convenient and the detecting accuracy is high.

Description

technical field [0001] The invention relates to a detection method of an angle measurement device, which is used for precise detection of the measurement accuracy of the angle measurement device, and belongs to the field of optical instrument detection. Background technique [0002] In the field of missile artillery launch, it is often necessary to measure the angular deformation of its launch platform, so various angle measurement equipment has been continuously developed. With the continuous improvement of measurement accuracy, the requirements for the detection accuracy of such equipment are also getting higher and higher. At present, this kind of angle measurement equipment is most commonly used to develop the principle of optical imaging. First, two target point light sources are imaged. By extracting the position coordinates and gray value of the spot on the CCD phase surface, the connection between the two target points can be obtained through calculation. The angle ...
