Study On Test Control Technique And Echo Processing Methods For 3-D Laser Scanner

With the rapid growth of digital technology recent years, there is art increasing need for large amount of raw data information in many different fields. The progress and development of computers and mechanism make the methods and technique of getting information diversified.3-D laser scanning technique is a way that uses laser pulse to scan the object to get the superficial characteristic information of the entity. It applies to the close quarters or middle distance scene of the objects in the real world. 3-D laser scanner has its outstanding performance in this field. Through connected with computer, 3-D laser scanner post processing technique can make the extensive use of the scanning result.The article has a deep study on test control technique and echo processing methods for improving the ranging precision of 3-D laser scanner. Firstly, the characteristic and the research work on the current international development trend of 3-D laser scanner are introduced. According to the need of system, the factors that affect the results of test control system subdivision driving are designed, analyzed and discussed. Furthermore, after analyzing popular methods applied in laser distance measure, on the basis of precision, analyze many methods to improve the ranging precision of echo data processing, compare the strongpoint and the disadvantage of the different methods, and through software simulation, prove the method is feasible. Using those echo data processing way, boost the precision of the 3-D laser scanner result.
