Abstract: A method for using a laser device includes: dividing laser devices into a first laser group and a second laser group, and turning on the laser device in the first laser group and processing the pole sheet; when any temperature value of a galvanometer and a field lens of the laser device in the first laser group reaches a set value, turning off the laser device in the first laser group, and turning on the laser device in the second laser group to continue processing the pole sheet; when any temperature value of the galvanometer and field lens of the laser device in the second laser group reaches the set value, turning off the laser device in the second laser group, and turning on the laser device in the first laser group to continue processing the pole sheet.

Abstract: The present disclosure provides an image processing method, apparatus and device, the method includes: acquiring a visible light image and a fluorescence image corresponding to a designated location inside a target object, where the designated location inside the target object includes diseased tissue and normal tissue; determining a to-be-cut boundary corresponding to the diseased tissue from a to-be-detected image, where the to-be-detected image is the fluorescence image or a fused image of the visible light image and the fluorescence image; and generating a target image, the target image includes the visible light image and the to-be-cut boundary.
