The invention relates to a method and arrangement for measuring the jumping distance especially in long jump and triple jump, in which the competitor jumps from a fixed starting line (10) onto the jumping ground (20) that is formed by a clearly defined area of sand etc., and in which the jumping distance is determined by the distance between the edge (14) of the trace left by the jumper's landing that is closest to the starting line and by the starting line (10). At least an essential part of the jumping ground (20) is filmed by a video camera (17) after the jump and from the video picture obtained the position of the said edge (14) on a measuring scale is determined by using a machine vision, the measuring scale having been calibrated in advance in relation to the starting line (10). |
