Ultra high precision elevation process for automatic transmission

The present invention patent relates to an ultra high level process for high-accuracy automatic transmission. A step, set up in the bottom of the forced transfer device of the elevation position of the laser total station, obtaining an initial value; step two, the camera stand reserved receiver means placed at the entrance; Step three, the electronic total station laser laser instrument playing the photographic camera receiver receiver means, a plurality of times ranging; after step 4 to give the vertical reference distance to a photographic laser total station receiver, the receiver device to obtain the photographic point switch point elevation, by the program automatically calculates the job level readings bi + 1.000m elevation point. The present invention solves the problems of the conventional methods by the height restriction, the same reference point may be accurately transmitted upwardly from a direct reading instrument, directly dedicated software for data processing, high degree of automation is 10 times the conventional efficiency, and eliminate the human error accumulated error, high precision.
