Disclosed a multi-station scanning global point cloud registration method based on graph optimization, including acquiring multi-station original three-dimensional point cloud data; based on initial registration of targets, completing initial registration of point cloud data at adjacent stations by virtue of the target at each angle of view; calculating a point cloud overlap area at adjacent angles of view, and calculating areas of overlap regions of adjacent point cloud by a gridded sampling method; constructing a fine registration graph structure, and constructing a fine registration graph by taking point cloud data of each station as a node of the graph and taking an overlap area of the point cloud data of adjacent stations as a side of adjacent nodes of the graph structure; and based on loop closure fine registration based on graph optimization, gradually completing point cloud fine registration of the whole aircraft according to a specific closure sequence.

Multi-station scanning global point cloud registration method based on graph optimization

A main board and a method for dynamically configuring PCIE ports thereof. The main board comprises a PCIE slot, a detecting circuit, an ROM, a chipset and a modifying circuit. The chipset comprises a Management Engine controller and several PCIE ports. The chipset has a Management Engine function or a similar function. The detecting circuit detects the PCIE slot to generate a current state parameter. The ROM stores a default configuration data. The modifying circuit coupled between the chipset and the ROM determines whether the default configuration data needs to be modified according to the current state parameter. When the default configuration data needs to be modified, the modifying circuit modifies the default configuration data according to the current state parameter, so that the Management Engine controller initially configures the PCIE ports according to the modified default configuration data. Thus, the dynamical configuration of the chipset PCIE ports is realized.
