A method for manufacturing a seat for measuring a standard driving posture of a human body includes: performing three-dimensional scanning on an auxiliary device to acquire a first point cloud data set; constructing N seat curves according to the plurality of groups of displacement data sets; correspondingly processing the N seat curves and the first point cloud data set to delete the point cloud data above the seat curves so as to obtain a second point cloud data set; and performing inverse modeling on the second point cloud data set to obtain a rigid seat model for manufacturing a rigid seat. The rigid seat manufactured through the method facilitates putting a dummy in a standard driving posture and also can avoid the problem that key sizes of the dummy are not correctly measured due to deformation of the seat surface.

A method for building a vehicle crash dummy skull model, includes: building an original skull model according to computed tomography scan data of a human skull; inserting a new first node according to a distance between adjacent first nodes on a hole boundary contour line, to obtain a target contour line; inserting a plurality of second nodes into holes according to the target contour line to obtain an intermediate boundary contour line; forming triangular nets according to the nodes on the target contour line and the intermediate boundary contour line; and with the intermediate boundary contour line as a new target contour line, returning to the operation of inserting a plurality of second nodes until the number of nodes of a final target contour line is less than or equal to a preset value. This embodiment is conducive to building of a skull model with a smooth cranial surface.
