Drivers affective states will transfer along with environmental changes during driving. The changes can affect directly drivers manipulation. The affective state is represented mainly as drivers propensity. It plays a significant role for researching the active driving and auto-driving systems to reveal the transformation mechanism of drivers propensity exactly in complex environment. Data of drivers propensity can be collected and analyzed through driving experiments in different two-lane environments from the angle of environmental change, especially evolution of vehicle group. It reveals transformation mechanism of drivers propensity under different environment conditions. Verification results show that the predictive outcomes which are gotten by transformation rule are consistent with that of real-time recognition. It also shows that the transformation mechanism revealed in this paper is scientific and reasonable.

Images matching is the basis of image registration. For their difference, a improved SURF(speeded up robust features) algorithm was proposed for the infrared and visible images matching. Firstly, edges were extracted from the images to improve the similarity of infrared and visible images. Then SURF algorithm was used to detect interest points, and the dimension of the point descriptor was 64. Finally, found the matching points by Euclidean distance. Experimental results show that some invalid data points were eliminated.

The optimal path planning plays an important role in the satellite navigation system. This paper uses the Dijkstra algorithm, which gives a shortest path first, to find a more effective travel decision. The decision combines the Dijkstra algorithm with the real-time traffic information and gives an effective travel plan. This system is developed under C# environment, achieves the goals of travel path planning and traffic guidance, and can supply a variety of travel plan to the traveler according to the difference influence factors.

A new accurate calibrating technique for intrinsic parameters and extrinsic parameters of CCD camera is described. The camera model is derived by the pinhole projection theory. Then other parameters of the model are resolved under the radial alignment constraints and orthogonal constraints. In order to get a fine initial guess for the nonlinear searching solution, the least square method is introduced, and finally uses radial alignment constraint method to get the results. The experimental results show that the mean absolute differences in x direction and y direction are 0.0070 and 0.1430 separately while the standard deviation are 0.5006 and 1.2046 separately.

Ancient wood structure usually has good anti-seismic performance because of structural characteristics. Mortise joint and tenon joint of wood structure component parts of the node can be very good energy dissipation and mitigate the effects of earthquake damage at the time of seismic action. Column foot and foundation can effectively reduce the seismic response with friction-sliding. It can give clear status evaluation from the perspective of applicability to protecting the ancient timber structures which is of great importance to protection.
