Online measurement method and three-dimensional modeling method of transparent glass hemispherical curved surface part

The invention belongs to the field of glass product processing, and relates to an online measurement method and a three-dimensional modeling method of a transparent glass hemispherical curved surface part, and the method comprises the following steps: 1) integrating a contact type three-dimensional probe into a processing head of etching equipment; 2) calibrating the contact type three-dimensional probe; 3) establishing a to-be-measured transparent glass hemispherical curved surface part sample coordinate system; 4) confirming relevant parameters of the transparent glass hemispherical curved surface part sample piece to be measured, and obtaining compensated relevant parameters after sinusoidal error compensation; (5) measuring the transparent glass hemispherical curved surface part sample piece to be measured by adopting the calibrated contact type three-dimensional probe on the basis of the compensated related parameters; and 6) obtaining the obtained measurement data through network port communication, and
