Method for acquiring focal length values, device for acquiring focal length values and detection equipment capable of calculating focal length of slide

Abstract

A method for acquiring focal length values, a device for acquiring focal length values, and a detection equipment capable of calculating the focal length of a slide are described. The method includes the following steps: acquiring a calibration slope value and a calibration intercept value of a detection equipment including a microscope; acquiring a height value of a slide by identifying a scale when a probe touches a carrier and the scale when the probe touches the slide, based on an image of the carrier; and calculating a calculation focal length value of the slide based on the calibration slope value, the calibration intercept value, and the height value.
