说明：  使用树莓派3b来实现无人驾驶汽车，使用ROS把各种传感器连接起来。(Using raspberry pie 3b to realize driverless car,and use ROS to connect all kinds of sensors.)

说明：  g各种调制波形的matlab生成代码 已经在实验过都可以用 对于基础学习的人帮助很大(The Matlab generation code for various modulated waveforms has been experimentally used to help people with basic learning.)

说明：  克里金(Kriging)插值法又称空间自协方差最佳插值法，它是以南非矿业工程师D．G．Krige的名字命名的一种最优内插法。克里金法广泛地应用于地下水模拟、土壤制图等领域，是一种很有用的地质统计格网化方法。它首先考虑的是空间属性在空间位置上的变异分布．确定对一个待插点值有影响的距离范围，然后用此范围内的采样点来估计待插点的属性值。该方法在数学上可对所研究的对象提供一种最佳线性无偏估计(某点处的确定值)的方法。(Kriging interpolation, also known as spatial autocorrelation optimal interpolation, is named after d.g.krige, a mining engineer in South Africa. Kriging method is widely used in groundwater simulation, soil mapping and other fields. It is a very useful geostatistical grid method. Firstly, it considers the variation distribution of spatial attributes in spatial position, determines the range of distance that affects the value of a point to be inserted, and then estimates the attribute value of the point to be inserted with the sampling points in this range. This method can provide the best linear unbiased estimation (the determined value at a certain point) for the studied object mathematically.)
