基于变频器的空间电压矢量PWM控制matlab程序设计与实现(Matlab program design and implementation of the inverter space voltage vector PWM control)

本程序用三边测量法来计算未知节点坐标且假设用于定位的锚节点位于等边三角形的三个顶点上。(This program uses trilateration to calculate the coordinates of unknown nodes and assume the anchor node for positioning in the equilateral triangle of three vertices.)

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.
