threshold:检测一条直线所需最少的曲线交点 minLineLength:线的最短长度,比这个线短的都会被忽略 maxLineGap:两条线之间的最大间隔,如果小于此值,这两条线就会被看成一条线 代码语言:txt AI代码解释 import cv2 import numpy as np # 标准霍夫线变换 def line_detection_demo(image): # 灰度图像 gray = c...
4.通过滑动窗口,拟合车道线 通过滑动窗口,得到左右车道线对应的(x,y)坐标,并使用numpy提供的多项式拟合函数polyfit()实现车道拟合。具体代码如下 deffind_line(warped):histogram=np.sum(warped[warped.shape[0]//2:,:],axis=0)x=[xforxinrange(len(histogram))]y=[histogram[i]foriinrange(len(histogram)...
二:HoughLinesP概率霍夫变换(是加强版)使用简单,效果更好,检测图像中分段的直线(而不是贯穿整个图像的直线) def line_detect_possible_demo(image): gray=cv.cvtColor(image, cv.COLOR_BGR2GRAY) edges= cv.Canny(gray,50,150, apertureSize=3) # apertureSize是sobel算子大小,只能为1,3,5,7lines = cv.Ho...
int threshold, // 阈值,只有获得足够交点的极坐标点才被看成是直线 double minLineLength = 0;// 最小直线长度 double maxLineGap = 0;// 最大间隔 ) 1. 2. 3. 4. 5. 6. 7. 8. 9. 二、代码演示 1.传入一张图像,把所有直线画出来。 void lineDetection(cv::Mat &cv_src, cv::Mat &cv_d...
line_detection(src) src= cv.imread('E:/imageload/louti.jpg') #调用上一个函数后,会把传入的src数组改变,所以调用下一个函数时,要重新读取图片 line_detect_possible_demo(src) cv.waitKey(0) cv.destroyAllWindows() 运行结果: 注意: 1.opencv的HoughLines函数是标准霍夫线变换函数,该函数的功能是通过...
def line_detection(image): gray=cv2.cvtColor(image,cv2.COLOR_BGR2GRAY) #apertureSize参数默认其实就是3 edges=cv2.Canny(gray,50,250,apertureSize=3) ''' 第一个参数,InputArray类型的image,输入图像,即源图像,需为8位的单通道二进制图像,可以将任意的源图载入进来后由函数修改成此格式后,再填在这里。
