Abstract: A multi-view vision inspection system includes a darkroom; and a plurality of cameras, the plurality of cameras including a plurality of first cameras, a plurality of second cameras and a plurality of third cameras, the plurality of first cameras being arranged spaced from one another at a top of an interior of the darkroom, the plurality of second cameras being arranged spaced from one another at a bottom of the interior of the darkroom, and the plurality of third cameras being arranged spaced from one another on a side wall of the interior of the darkroom in a circumferential direction of the darkroom. The multi-view vision inspection system can measure each angle of a workpiece to be inspected by using the plurality of cameras above.

Abstract: 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 N0 and a right side contour gap point set N1; computing a mean distance vector ? between contours on two sides of the gap of the measured vehicle body according to the left side contour gap point set N0 and the right side contour gap point set N1; and computing the gap d of the measured vehicle body according to the mean distance vector ?.
