The invention discloses an anti-collision early warning method for a crane. The anti-collision early warning method comprises the following steps: shooting a plurality of photos of a monitoring area at certain time intervals; obtaining the contour of the object in each photo and the coordinate of the object corresponding to the contour; comparing the contour coordinates of the object in the pictures shot in the adjacent shooting time, and judging whether the contour of the object moves or not; judging that the contour of the object moves, marking the contour of the moving object as a first marking line, and marking the contour of the static object as a second marking line; when the distance between the first marking line and the second marking line reaches an alarm threshold value, sound-light alarm is triggered. The invention further discloses an anti-collision early warning device for the crane. By means of the anti-collision early warning method and device for the crane, the movement condition of the crane can be monitored in a complex operation area in a multi-angle mode; a moving object is tracked in real time, and the moving object is prevented from colliding with a static object.

    本发明公开了一种吊车防碰撞预警方法,包括:每间隔一定的时间对监测区域拍摄多张照片;获取每一张照片中物体的轮廓及该轮廓所对应物体的坐标;对比相邻拍摄时间内所拍摄照片中物体的轮廓坐标,判断物体轮廓是否有发生移动;判断物体的轮廓有发生移动,将移动物体的轮廓标记为第一标记线,将静止物体的轮廓标记为第二标记线;当第一标记线与第二标记线的距离达到报警阈值时,触发声光报警。本发明还公开了一种吊车防碰撞预警装置。实施本发明的吊车防碰撞预警方法及装置,能够在复杂的作业区域中多角度的监测吊车的活动情况;实时追踪移动物体,防止移动物体与静止物体发生碰撞。
