In recent years, scannerless ladar has developed rapidly. Laser radar are ideally suitable for recognizing objects, detection, target tracking or obstacle avoidance, because of the high angular and range resolution. The results of experiments and theory analzing demonstrate that proposed method could realize the dynamic measurement of handheld laser
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. Finally, a recognition method of coding maker is proposed, with the use of the distance recognition, it is more efficient. Compared with other coding methods,the marker with this method is simple to match and can avoid the shading for the object. Secondly, the coding marker is introduced to solve the data matching, a random coding method is proposed. By those, the real-time orientation of laser scanner is realized and the efficiency is improved. Firstly, a laser scanner based on binocular vision is designed with double camera and one laser head. There are three major contributions in the paper. 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. 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. 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.

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. In particular, traditional Laser Scanner must Keep stable to scan and measure coordinate transformation parameters between different station.
Little use has been made of dynamic measurement, that are appropriate for more problems and situations. Handheld laser scanner automatic registration based on random codingĬurrent research on Laser Scanner often focuses mainly on the static measurement.
