Abstract

The invention relates to a spectral confocal displacement sensor wavelength calculation method and system, a server and a readable storage medium, and the method comprises the steps: collecting an image, refracted by a convex lens, of light on the surface of a measured object through an image collection device, generating a gray scale matrix, and obtaining a confocal position according to the grayscale matrix; because the confocal positions of the light rays with different wavelengths at the same position are different after the light rays are refracted by the convex lens, the wavelength of the confocal light rays can be obtained according to the confocal positions, and the technical problem that a spectral confocal displacement sensor wavelength calculation method in the prior art depends on a spectrograph is solved. The technical effect that the wavelength can be calculated by using the image acquisition device is achieved, and the measurement precision of the spectral confocal displacement sensor is improved to a certain extent.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a wavelength calculation method, system, server and storage medium of a spectral confocal displacement sensor. Background technique [0002] The spectral confocal displacement sensor is a sensor based on the confocal principle and uses polychromatic light as the light source. Its measurement accuracy can reach the nanometer level, and it can be used for the measurement of objects with diffuse reflection or mirror reflection on the surface. In addition, the spectral confocal displacement sensor can also measure the thickness of transparent objects in one direction. Due to its high-precision characteristics in measuring displacement, for single-layer and multi-layer transparent objects, in addition to accurately measuring the displacement of the object, it can also measure its thickness in one direction. [0003] The spectral confocal displacement sensor is a non-contact measureme...
