Three-dimensional range finder

The invention discloses a three-dimensional range finder, and belongs to the technical field of optical-mechanical-electrical integration. Comprising a bearing body, a distance measuring device and a control device, the distance measuring device comprises a distance measuring device, a horizontal rotating device, a vertical rotating device and a control element, and the X-axis distance measuring direction of the distance measuring device is located on the horizontal plane parallel to the bottom face of the bearing body; the horizontal rotating device is installed on the bearing body and used for switching the range finder to the Y-axis range finding direction, and the Y-axis range finding direction is perpendicular to the X-axis range finding direction. The vertical rotating device is installed on the bearing body and used for switching the distance measuring direction of the distance measuring device to the Z-axis distance measuring direction, the Z-axis distance measuring direction is perpendicular to the Y
