The high-low measuring device comprises an object measured by the height measuring device, a distance measurement sensor which is provided in a known relationship with the object and measures a distance to a construction surface, a projecting device for projecting a high-low information, and an arithmetic control module, the arithmetic control module calculates a high-low information of the construction surface based on a height information of the object measured by the height measuring device and a distance information measured by the distance measurement sensor, and the projecting device projects the high-low information onto the construction surface.",
