FOCUS LOCKING METHOD AND APPARATUS FOR MICROSCOPE

WIPO Patent Application WO/2024/045889

A1

Disclosed are a focus locking method and apparatus for a microscope. The method comprises: collecting displacement data of a Z-axis shifter and image data of a slide in real time (101); according to the displacement data and the image data, performing curve fitting processing, so as to obtain a linear relationship between the displacement data and the image data (102); and according to the linear relationship, adjusting the position of the Z-axis shifter, so as to realize focus locking (103). Therefore, curve fitting processing and the acquisition of a linear relationship require no additional hardware device, but can be realized on a computer by means of software, thereby reducing the cost generated by using an additional hardware device. In addition, by means of the real-time collection of displacement data of a Z-axis shifter and image data of a slide, in combination with a calculated linear relationship, the adjustment of the Z-axis shifter can be performed in real time, thereby improving the precision of focus locking.
