Matlab的一个控制摄像头程序用例,提取视频信号(A Matlab program to control the camera with the case, extract the video signal)

二次多项式拟合大地水准面，采用matlab编写的，关于拟合出来的图像感觉有些问题。。希望大家指正(Quadratic polynomial fitting geoid, using matlab prepared some questions about the fitting out of the picture feel. . I hope you correct)

在二进制数字调制中，当正弦载波的相位随二进制数字基带信号离散变化时，则产生二进制移相键控(2PSK)信号。 通常用已调信号载波的 0°和 180°分别表示二进制数字基带信号的 1 和 0，用matlab实现其功能。(In binary digital modulation, phase when the sine wave with the discrete binary digital baseband signal changes, then generates a binary phase shift keying (2PSK) signal. Usually expressed respectively 1 and 0 binary digital baseband signal with the modulated signal carrier of 0 ° and 180 °, to achieve its function with matlab.)

说明：  基于MATLAB的有源滤波器的实现，很简单，能看懂。(The realization of active filter based on MATLAB is simple and understandable.)

Matlab中没有现成的Hermite插值函数，必须编写一个M文件实现插值。 设n个节点的数据以数组x0 （已知点的横坐标）， y0（函数值）， y1（导数值）输入（注意Matlat的数组下标从1开始）， m个插值点以数组x 输入，输出数组y 为m 个插值。编写一个名为hermite.m的M文件。 (Matlab is not off-the-shelf Hermite interpolation function, we must realize the preparation of a document M interpolation. N nodes for the data to an array x0 (known point of abscissa), y0 (function value), y1 (numerical derivative) input (note the subscript Matlat array starting at 1), m to the array of interpolation points x input and output array y for m months interpolation. Hermite.m the preparation of a M-file.)
