High cost sensors are needed to measure relative 6-DOF motion with accuracy at a remote distance, such as DGPS and 3-D laser scanners. This paper proposes a sensing system composed of low cost sensors but with high accuracy and outdoor robustness. The system is composed of three laser 1-D sensors with a vision camera at the target screen. The designs and algorithm principles for this sensing system are described. Static motion experiments are conducted to evaluate the system accuracy. Results showed that the proposed system has an accuracy of 3mm at a 30m distance range under indoor and outdoor condition.
