This thesis have introduced a design which is a 3D scene reconstruction system based on Android.The system have the function of representation of reality the state of motion of the objects by collecting the data about the mov ing posture and velocity vector of the moving objects.Then handle these data by data processing and wireless transmission.The core of this system is installing related sensor on an object which just have three degrees of freedom but is not capable of translation.Throughout collecting and analysing the data,transforming useful data with upper monitor which is based on the protocol of UDP,then rendering the 3D screen with An droid powerful graphics interface.Finally,realization of real scene in the cli ent of the upper monitor.By system test this system has reached the expected based function.Moreover,the function of the systems is powerful.In fact,it could play an important role in traffic accident scene reduction and could meet many other realistic commands in other conditions.
