This invention relates to a microscopic scanning focusing method and system adapted for live cell slides. By establishing a focal plane height model reflecting the spatial mapping relationship between the plane coordinates of the microgroove and the focal height at the bottom of the groove, the traditional large-scale focusing search starting from zero point by point is simplified to a local search guided by predicted focal height, significantly reducing the focusing time for each microgroove. Within the local search area, the sharpness characteristics and cell texture characteristics of the microscopic image are combined to distinguish between the false focal peaks generated by the liquid-gas interface and the true focal peaks of the cell layer at the bottom of the groove, so that the focusing results are not affected by the reflection from the transparent culture medium surface, ensuring that the focus is always locked on the cell layer at the bottom of the groove rather than the liquid surface. Based on this, the light source is triggered for short-time exposure imaging only when the objective lens and stage reach the focal height of the cell layer at the bottom of the groove determined after eliminating false focal peaks. Thus, while taking into account scanning efficiency, the experimental repeatability and data reliability of long-term serial observation of live cells are guaranteed.
