Abstract: The application discloses a parallel laser line scanning device and a method for measuring crack width and spalling area. The device includes a laser source configured to emit two beams of laser light in parallel to each other to scan a surface; a camera configured to collect an image of the scanned surface, and the camera comprising a lens and an image sensor; a positioning rod; and a controller configured to process an image of scanned surface to obtain a pixel scale of a crack or three-dimensional coordinates of contour points of a spalling, and determine an actual crack width in the scanned surface according to the pixel scale of the crack, or determining an actual spalling area according to the three-dimensional coordinates of the contour points of the spalling. The device facilitates faster and more objective evaluations of building conditions, contributing to improved structural health monitoring and maintenance decision-making.

Abstract: A method includes obtaining a communication connection relationship between a first game client and a target virtual server in response to a target watching request triggered on the first game client for requesting to synchronously display in the first game client a game picture of a virtual game battle in which a second game client participates, in response to obtaining a target watching payload associated with the virtual game battle, adjusting a process number of target process(es) included in the target virtual server according to the target watching payload, and, in response to obtaining game picture data of the virtual game battle by the target virtual server after being adjusted, transmitting the game picture data to the first game client through the communication connection relationship.
