利用OPENCV函数库所进行的极坐标变换。利用Hough变换进行直线、圆检测。计算一副彩色图像的色度-饱和度直方图。用卡尔曼滤波器跟踪一个旋转点。-OPENCV library use conducted by polar transformation. The use of a straight-line Hough transform, circle detection. Calculating a color image of the color- saturation histogram

通过canny算子和hough变换得到的多条竖直线计算垂直方向上的灭点-By canny operator and the hough transform for calculation of a number of vertical lines on the vertical vanishing point

该程序主要是用来计算两条直线的距离，希望对大家有帮助。-The program is used to calculate the distance of the two straight lines, we hope to help.

这是根据每周一练的第一周题目要求做的。先检测出两平行直线，再计算出其距离。-This is based on the weekly practice the first week of the subject is asked to do. First detected two parallel lines, then calculate its distance.
