Laser surveying system for setting out

Abstract

The present disclosure relates to the field of architecture and civil engineering, in particular to a construction surveying system. A laser surveying system for setting out comprises a horizontal laser emitter for emitting horizontal laser beams in a sector; a vertical laser emitter for emitting vertical laser beams in a sector; a leveling laser rangefinder; and at least one laser receiver; The horizontal and vertical laser beams in a sector intersect at an intersection line, an optical axis of ranging beams of the leveling laser rangefinder coincides with the intersection line, the laser receiver includes a laser entrance window and a laser plummet, and an axis of the laser entrance window coincides with the intersection line. According to the present disclosure, the aim direction of the laser emitter can be indicated for operators by the intersection line of the laser beams in a sector. The distance between the laser emitter and the laser receiver is measured by the laser rangefinder whose axis coincides with the intersection line, and the beams are projected onto a surface to be surveyed by the laser plummet of the laser receiver so that the aim direction can be indicated for operators easily regardless of sloping or uneven ground, and the operator can mark coordinates along on the laser beams.
