A three-dimensional (3D) structured light camera based method and system for measuring a gap of a vehicle body is provided. The method includes: obtaining point cloud data obtained by a 3D structured light camera scanning the gap of the measured vehicle body; with a group of point cloud data of the gap of the measured vehicle body in a transverse direction as a contour, extracting contour gap points of each contour, so as to obtain a left side contour gap point set Nand a right side contour gap point set N; computing a mean distance vector {right arrow over (τ)} between contours on two sides of the gap of the measured vehicle body according to the left side contour gap point set Nand the right side contour gap point set N; and computing the gap d of the measured vehicle body according to the mean distance vector {right arrow over (τ)}.
