Current research on Laser Scanner often focuses mainly on the static measurement. Little use has been made of
dynamic measurement, that are appropriate for more problems and situations. In particular, traditional Laser Scanner
must Keep stable to scan and measure coordinate transformation parameters between different station. In order to make
the scanning measurement intelligently and rapidly, in this paper ,we developed a new registration algorithm for
handleheld laser scanner based on the positon of target, which realize the dynamic measurement of handheld laser
scanner without any more complex work. the double camera on laser scanner can take photograph of the artificial target
points to get the three-dimensional coordinates, this points is designed by random coding. And then, a set of matched
points is found from control points to realize the orientation of scanner by the least-square common points
transformation. After that the double camera can directly measure the laser point cloud in the surface of object and get
the point cloud data in an unified coordinate system. There are three major contributions in the paper. Firstly, a laser
scanner based on binocular vision is designed with double camera and one laser head. By those, the real-time
orientation of laser scanner is realized and the efficiency is improved. Secondly, the coding marker is introduced to
solve the data matching, a random coding method is proposed. Compared with other coding methods,the marker with
this method is simple to match and can avoid the shading for the object. Finally, a recognition method of coding maker
is proposed, with the use of the distance recognition, it is more efficient. The method present here can be used widely in
any measurement from small to huge obiect, such as vehicle, airplane which strengthen its intelligence and efficiency.
The results of experiments and theory analzing demonstrate that proposed method could realize the dynamic
measurement of handheld laser scanner. Theory analysis and experiment shows the method is reasonable and efficient.
