Title:
THREE-DIMENSIONAL PROBE SYSTEM AND THREE-DIMENSIONAL MEASURING METHOD BASED ON HYDROMECHANICAL PRINCIPLE
Document Type and Number:
WIPO Patent Application WO/2015/103931
Kind Code:
A1
Abstract:
Three-dimensional probe system and three-dimensional measuring method based on hydromechanical principle. The probe system comprises an air pipe (8) and an air probe (61) connected to one end of the air pipe. Pressure sensors (62, 63) used for detecting air pressures of two different points of an air channel are arranged in the air channel, or a flow sensor used for detecting an air flow of the air channel is arranged in the air channel. According to the three-dimensional probe system and three-dimensional measuring method, work is conducted by using the air probe to suck in or eject air, feedback control is conducted by making use of the characteristic that the static pressure of air in an air channel pipe formed by the air probe and the air pipe changes as the distance from the air probe to the surface of a detected object changes, so that the present invention overcomes the defects of the existing mechanical and electrical contact measuring heads and optical contactless measuring heads and has the advantages of a simple structure, high measurement accuracy, rapid scanning speed, strong adaptability and the like.
