The purpose of this disclosure is to improve the accuracy of 3D conversion of an object point cloud when performing 3D conversion of the object point cloud obtained by using laser or radar and to reduce the amount of calculation in the axial direction of the three-dimensional space coordinates where the object point cloud is mapped. In this disclosure, the absolute value of the difference between vehicle attitude data at a high sampling frequency and vehicle attitude data at a low sampling frequency is calculated. When the absolute value of the difference is small, the vehicle attitude data at the high sampling frequency is culled to output the vehicle attitude data at the low sampling frequency, thereby reducing the amount of calculation in the axial direction of the three-dimensional space coordinates where the object point cloud is mapped. In contrast, when the absolute value of the difference is large, the vehicle attitude data at the high sampling frequency is output, thereby improving the accuracy of 3D conversion of the object point cloud. Finally, 3D conversion of the object point cloud is performed on the basis of the vehicle attitude data and the data of the object point cloud.
