Space positioning method based on double-rotating laser plane transmitter network

The invention discloses a space locating method that is based on a network of planar dual-rotation laser transmitters, the rotation of three or more than three rotating transmitters are driven by an alternate current servo motor, the rotating transmitters that have two linear laser devices arranged on the head part transmit laser signals continuously to the surrounding space, the time distance of OZ pulse between a laser peak position that is sampled by a receiver module that takes a photocell as a sensor and a time origin is converted into a rotating angle of a laser plane, and consequently, the equation of the laser plane where measured points are positioned is deduced, an equation of a straight line that runs through the measured points is further obtained, an equation set is built according to the intersection method of multiple lines, and finally the equation set is solved by the least square method, thus obtaining the coordinate positions of the measured points. The space locating method avoids object aiming when measuring, and improves measuring speed and efficiency.
