Abstract: A system and a method for calibrating laser processing parameters comprises positioning a laser module at a first height from a work platform, capturing with a camera module an image of a first light spot projected on the work platform by a visible-light emitter to obtain a first position data of the first light spot on an image plane of a lens of the camera module at the first height; positioning the laser module at a second height from the work platform different from the first height, capturing with the camera module an image of a second light spot projected on the work platform by the visible-light emitter to obtain a second position data of the second light spot on an image plane at the second height, obtaining a conversion formula of an actual distance, and plugging the first and second position data into the conversion formula.

Abstract: This application relates to the field of cloud computing, and specifically, to a method for providing an edge service for a terminal by using a resource of an edge resource cluster in a cloud computing system. The cloud computing system includes a central resource cluster and at least one edge resource cluster. The method includes: a management node deployed in the central resource cluster determines a target execution node based on an edge service application range that is specified by a tenant or that is determined by the management node based on information about a tenant; the target execution node determines, according to an edge service policy sent by the management node, a target edge node from at least one edge node deployed in the at least one edge resource cluster; and the target execution node further forwards an edge service request to the target edge node.
