Abstract

A measuring method of the swing angle of a swing nozzle relates to an angle measuring technology, specifically to a measuring technology of the swing angle of the swing nozzle. By the adoption of the measuring technology, the swing angle of the assembled nozzle can be measured. The measuring method is realized based on the measuring system, in the measuring system, an image acquisition device is used to continuously acquire image information of the nozzle to be measured and send the acquired image information to an image processing computer. The image processing computer is used to process the received image information and acquire swing angle information of the nozzle to be measured according to the continuously acquired image information. According to the measuring method, the step of calibrating the measuring system is firstly carried out, followed by the step of measuring the swing angle of the nozzle. The steps are the following two steps which are carried out repeatedly: firstly, the step of acquiring the image of the nozzle; and secondly, the step of calculating the swing angle of the nozzle to be measured according to the acquired image. The invention is suitable for measuring the swing angle of the assembled nozzle.

Description

technical field [0001] The invention relates to an angle measurement technology, specifically designed to a measurement technology for the swing angle of a swing nozzle. Background technique [0002] In the prior art, in the measurement of the angle of the nozzle in the unassembled state, the measurement can be realized by placing a displacement sensor or an acceleration sensor on the nozzle. In this case, the assistance of larger-sized tooling equipment is required. However, when the nozzle is in a fully assembled state, due to space constraints, the nozzle obviously cannot use tooling equipment, so that the contact sensor cannot be used. Contents of the invention [0003] In order to realize the measurement of the swing angle of the assembled spray pipe, the present invention designs a method for measuring the swing angle of the swing spray pipe. [0004] The measurement method of the swing angle of the present invention is realized based on the following measurement sy...
