fit

A commonly used control device called a programmable logic controller, or a PLC, is used to read a set of digital and analog inputs, apply a set of logic statements, and generate a set of analog and digital outputs. Using the example in the previous paragraph, the room temperature would be an input to the PLC. The logical statements would compare the setpoint to the input temperature and determine whether more or less heating was necessary to keep the temperature constant. A PLC output would then either open or close the hot water valve, an incremental amount, depending on whether more or less hot water was needed. Larger more complex systems can be controlled by a Distributed Control System (DCS) or SCADA system.

包含了目前针对陀螺仪常用的小波滤波，卡尔曼滤波，前向线性预测FLP滤波，还有小波滤波与FLP滤波方法的融合算法，并对滤波前后进行了功率谱密度分析和比较，画出了功率谱密度图，还有滤波效果比较图，最后还有相应的Allan方差分析。内容丰富，只要把数据load进去就可以了（默认长度为4096,可以更改的），简单易上手，初学者也能看懂。其中FLP滤波，1和2文件分别为东西方向互补的数据。(Gyro filtering algorithm collection)

很好用的，生成归零码的程序，速度快， (R-Z code )

说明：  Edge detection result should be enhanced using linear method like Median filter to remove the garbage around the pupil to gain clear pupil to determine perfect centre. Get the centre of the pupil by counting the number of black pixels (zero value) of each column and row. Then get each row and column that has the maximum number of these black pixels. Then determine the center by simple calculation according to the image coordinate to set it correct on the image, consequently we can determine the radius of the pupil. Thus we can find the pupillary boundary (inner). A similar procedure is extended by using a coarse scale to locate the outer boundary (limbus) which can be apparent by using the mid-point algorithms of circle and ellipse.
