Description: 在本问题的求解中，修桥和挖隧道是两个相类似的求解过程，我们将求解过程分为两个部分：第一、对河岸边一固定点 ，将桥修在 处时，求解由起始点 到经固定点 到居民点 的最短路线。第二、如何确定 的位置，使得总路线的费用最小。我们分别用了两个模型来进行这两部分内容的求解。模型一、针对坡度的限制，利用小区域内的局部最优来达到全局最优。模型二、列出点 有一定的位移时，可以减少的费用 的函数方程，然后利用河岸附近等高线较紧密，公路不能沿偏离等高线方向前进的特性，求出减少的费用 的条件极值，从而确定最佳修桥地点 。最后，我们利用模型一、二的原理对隧道部分的公路做了同样的优化设计，然后得出总的修路费用估计为324万元，较合理。最后，我们对整个做法的误差及合理性做了分析。-in solving this problem, building bridges and two tunnels are dug similar to the solution process, we will be solving process is divided into two parts : the first, on the banks of the river a fixed point of the bridge repair in the Department, from the starting point to solve by the fixed point to settlements in the shortest routes. Second, how to determine the location, making the cost of the smallest general line. We were using the two models, both part of the solution. One model, the slope of the restrictions against use of the local small areas to achieve optimum global optimum. Model 2, listing a certain point of displacement, can reduce the cost of the equation, and then using the riverbank near the contours more closely, not along the highway from contour direction of the character

Description: 这个例子做的是去年全国电子电子设计大赛E题，悬挂运动控制系统（E题），我只做了画线和画圆两个部分，纯粹是玩，所以精度不是很高，终点定位精度误差差不多0.5cm左右，画圆在两个斜率无穷大区误差较大需要修正。
一开始我用的是L297+L298驱动，感觉脉冲相位控制比较麻烦，后来想到avr相对51的速度，用B口模拟脉冲，L293驱动。电机我用的是两个42BYG四相八拍六线步进电机，资料很好找。
这个试验做起来可能有点麻烦，比赛的时候需要特定的板子，就象附件E题里所示，注意电机转动的时候不能让绕线重叠，会严重影响精度，绳子要用无弹性的，我用的是去渔具店买的尼龙的无弹性渔线。

Description: 对于较粗的样本点集 hough 算法是不可能做到检测全部直线的. 另一方面 hough 还会测出许多不存在的直线. 在应用的时候只能根据需要自己标定 精度.
以下是我在MATLAB下开发的hough函数 输入一个灰度图形矩阵, 返回 最长直线斜率. 用来做图形倾斜校正的. 希望贴出来还能有点用吧~-For a sample point set coarse algorithm hough it is not possible to do all the straight line detection. Hough will be measured on the other hand, much of the straight line does not exist. At a time when the application can only be based on the needs of calibration accuracy of their own. The following is in my MATLAB hough function developed under a gray-scale graphics input matrix, the slope of a straight line back up. to make graphics tilt correction. I hope it can paste a bit with it ~

Description: * FILE: least-squares.c
* This program computes a linear model for a set of given data.
*
* PROBLEM DESCRIPTION:
* The method of least squares is a standard technique used to find
* the equation of a straight line from a set of data. Equation for a
* straight line is given by
* y = mx + b
* where m is the slope of the line and b is the y-intercept.
*
* Given a set of n points {(x1,y1), x2,y2),...,xn,yn)}, let
* SUMx = x1 + x2 + ... + xn
* SUMy = y1 + y2 + ... + yn
* SUMxy = x1*y1 + x2*y2 + ... + xn*yn
* SUMxx = x1*x1 + x2*x2 + ... + xn*xn
*
* The slope and y-intercept for the least-squares line can be
* calculated using the following equations:
* slope (m) = ( SUMx*SUMy - n*SUMxy ) / ( SUMx*SUMx - n*SUMxx )
* y-intercept (b) = ( SUMy - slope*SUMx ) / n
