PCA
PCA算法。PCA的目的是找到能够分离出最大方差的方向,所以首先求原来所有数据三个维度上的协方差,然后求这个协方差的特征值,最大特征值为第一个方向,从此以此类推。(PCA algorithm. The purpose of PCA is to find able to isolate the direction of maximum variance, so first find all the data in three dimensions on the original covariance, and then find the eigenvalues of the covariance, the biggest feature is the first in one direction, from and so on.)

直接序列扩频系统(DS,Direct Sequence)又称为直接序列调制系统或伪噪声系统(PN 系统),简称为直扩系统,是目前应用较为广泛的一种扩展频谱系统。要传送的信息经伪随机序列编码后对载波进行调制。在发信端越冬用扩频序列去扩展信号的频谱,在收信端,用相同的扩频友序列进行解扩,将展宽的频谱扩展信号还原成原始信号。因为伪随机序列的速率远大于要传送信息的速率,所以受调信号的频谱宽度将远大于要传送信息的频谱宽度,帮称之为扩频(Direct sequence spread spectrum (DS, Direct Sequence) modulation system, also known as direct sequence or pseudo-noise system (PN system), referred to as direct expansion systems, is currently the more widely used as a spread spectrum system. To send the information encoded by the pseudo-random sequence of carrier modulation. End of winter in the letter to extend the signal with the spreading sequence of spectrum, in the end prepared to receive and use the same sequence spread spectrum despreading friends, broadening the spectrum to restore the original signal expansion signals. Because the rate of pseudo-random sequence is much larger than the rate of information to be sent, so the frequency spectrum by adjusting the width of the spectrum is much larger than the width of the information to be sent to help is called spread spectrum)

说明: 利用Dijkstra算法来求网络图的最短路径,找到从起点P1到终点Pn的最短路径,由于上述算法使用了连接线中点的条件,不是整个规划空间的最优路径,然后利用遗传算法对找到的最短路径各个路径点Pi (i=1,2,…n)调整,让各路径点在相应障碍物端点连线上滑动(Use Dijkstra algorithm to find the shortest path network diagram to find the starting point P1 to the end of Pn from the shortest path algorithm is used as the midpoint of the condition of cable, not the entire optimal path planning of space, and then use genetic algorithm to find shortest path of each path points Pi (i = 1,2, ... n) adjusted to the path of obstacles in the corresponding endpoint connection point slide)
