Abstract
A method for measuring the motion response of a dummy in a crash test comprises: acquiring images of a measurement mark by a camera during the crash test, wherein the measurement mark is fixed on a part to be measured of the dummy, and the dummy is set in association with a preset platform; determining first coordinate positions of the measurement mark in the images; determining corresponding second coordinate positions of the first coordinate positions in a static coordinate system according to a preset conversion relationship, wherein the X-axis of the static coordinate system is parallel to the motion direction of the preset platform, the Y-axis of the static coordinate system is perpendicular to the motion direction of the preset platform; and determining a motion response trajectory of the part to be measured according to an initial position of the part to be measured and the second coordinate positions.
