Occupant injuries are always possible in a rollover accident, one of the major accidents in a bus. Thus the structure of body frame should have sufficient strength to protect passengers under accidental loads. ECE regulation No. 66 prescribes that survival space shall be preserved in the passenger compartment during and after the structure has been subjected to rollover test.
Rollover test on a body section was completed according to the regulation. The coordinates of body section before and after rollover were measured, and it was checked that the structure still complied with the requirements of survival space. Direct measurement by on a bus is difficult because of its large size. Thus photogrammetry by photographing and 3 dimensional digital modeling was introduced and the coordinates of each point were measured through this method.
