Virtual assembly method and device, equipment and medium

[0026] figure 1 It is a flow chart of a virtual assembly method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of virtual assembly of equipment. Typically, this method can be applied to virtual assembly of equipment in the aerospace field. The method can be performed by a virtual assembly device.

[0027] see figure 1 , the method specifically includes the following steps:

[0028] Step 110, according to the collected original point cloud data of the part to be assembled, determine the point cloud data to be registered and the reference point cloud data.

[0029] Among them, point cloud data refers to a set of vectors in a three-dimensional coordinate system. These vectors are usually expressed in the form of X, Y, Z three-dimensional coordinates, and are generally mainly used to represent the outer surface shape of an object. Not only that, in addition to the geometric position information represented by (X, Y, Z), point clo

[0065] Figure 5 It is a schematic structural diagram of a virtual assembly device provided by an embodiment of the present invention. refer to Figure 5 , the device may specifically include: a point cloud data determination module 210 , a registration weight determination module 220 and a registration module 230 .

[0066] Wherein, the point cloud data determination module 210 is used to determine the point cloud data to be registered and the reference point cloud data according to the collected original point cloud data of the part to be assembled;

[0067] A registration weight determination module 220, configured to determine the registration weight between the to-be-registered point and the associated reference point according to the allowable error of the to-be-assembled part;

[0068] The registration module 230 is configured to perform point cloud registration on the point cloud data to be registered and the reference point cloud data according to the registration weig
