Abstract
A method for measuring deformation of dummy rib, includes: controlling a plurality of laser device groups to slide along corresponding curve segments respectively, and executing the following steps when the laser device groups slide to each sampling point, to obtain a degree of deformation at a position, corresponding to the sampling point, on to-be-measured dummy rib, the following steps including: controlling a laser range finder to emit a laser beam in a normal vector direction of a tangent corresponding to a position on a slide rail; determining whether the laser range finder receives corresponding reflected laser. This embodiment can have advantages of simple operation, low cost, and high accuracy.
