下面是一段 Python 代码,可以用来实现利用摄像头控制电机进行视觉追踪:import cv2
import numpy as np # capture the video
cap = cv2.VideoCapture(0) while True:
# capture the frame
_, frame = cap.read()
# convert to grayscale
gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
# detect edges
edges = cv2.Canny(gray, 100, 200)
# draw contours
contours, _ = cv2.findContours(edges, cv2.RETR_TREE, cv2.CHAIN_APPROX_NONE)
# get the highest contour
if len(contours) > 0:
c = max(contours, key = cv2.contourArea)
# calculate the centroid
M = cv2.moments(c)
cx = int(M['m10']/M['m00'])
cy = int(M['m01']/M['m00'])
# move the motor to the centroid
# motor.moveTo(cx, cy)
# draw the centroid on the frame
cv2.circle(frame, (cx, cy), 5, (0, 0, 255), -1)
# show the frame
cv2.imshow('frame', frame)
# break the loop if 'q' is pressed
if cv2.waitKey(1) & 0xFF == ord('q'):
break
# release the video capture
cap.release()
cv2.destroyAllWindows()
