OpenCV 赛道图片识别:灰度分析与数据显示
要基于灰度识别进行赛道图片识别并显示距离、倾斜度和亮度数据,可以按照以下步骤进行:
- 导入所需的库和模块:
import cv2
import numpy as np
- 读取图片并转换为灰度图像:
image = cv2.imread('track_image.jpg')
gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)
- 进行边缘检测:
edges = cv2.Canny(gray, 50, 150)
- 根据边缘检测结果找到直线:
lines = cv2.HoughLinesP(edges, 1, np.pi/180, threshold=100, minLineLength=100, maxLineGap=10)
- 计算直线的倾斜度:
angles = []
for line in lines:
x1, y1, x2, y2 = line[0]
angle = np.arctan2(y2 - y1, x2 - x1) * 180 / np.pi
angles.append(angle)
average_angle = np.mean(angles)
- 计算明暗亮度数据:
brightness = np.mean(gray)
- 计算远近距离数据:
distance = 1 / (brightness / 255)
- 在原始图像上绘制直线和数据:
for line in lines:
x1, y1, x2, y2 = line[0]
cv2.line(image, (x1, y1), (x2, y2), (0, 255, 0), 2)
cv2.putText(image, 'Angle: {:.2f}'.format(average_angle), (10, 30), cv2.FONT_HERSHEY_SIMPLEX, 1, (0, 0, 255), 2)
cv2.putText(image, 'Brightness: {:.2f}'.format(brightness), (10, 60), cv2.FONT_HERSHEY_SIMPLEX, 1, (0, 0, 255), 2)
cv2.putText(image, 'Distance: {:.2f}'.format(distance), (10, 90), cv2.FONT_HERSHEY_SIMPLEX, 1, (0, 0, 255), 2)
- 显示结果:
cv2.imshow('Track Image', image)
cv2.waitKey(0)
cv2.destroyAllWindows()
这样就可以基于灰度识别进行赛道图片识别,并在原始图像上显示倾斜度、明暗亮度和远近距离数据。
