我正在尝试在python中将相机图像叠加到相机上。我可以将图像叠加到另一个图像上,但是当我将相同的东西应用到我的相机上时它不起作用。到目前为止,这是我的代码:
#!/usr/bin/python
import cv2
import time
cv2.cv.NamedWindow("Hawk Eye", 1)
capture = cv2.cv.CaptureFromCAM(0)
cv2.cv.SetCaptureProperty(capture, cv2.cv.CV_CAP_PROP_FRAME_WIDTH, 800)
cv2.cv.SetCaptureProperty(capture, cv2.cv.CV_CAP_PROP_FRAME_HEIGHT, 600)
x_offset=y_offset=50
arrows = cv2.imread("arrows.png")
while True:
webcam=cv2.cv.QueryFrame(capture)
#webcam[y_offset:y_offset+arrows.shape[0], x_offset:x_offset+arrows.shape[1]]=arrows
cv2.cv.ShowImage("Hawk Eye", webcam)
if cv2.cv.WaitKey(10) == 27:
break
cv2.cv.DestroyAllWindows()
如果我取消注释:
img[y_offset:y_offset+arrows.shape[0], x_offset:x_offset+arrows.shape[1]]=arrows
施加图像的线条,它只显示相机输入,但是当我在循环中添加它时,它会停止工作。谢谢!

使用cv2 API可以正常工作:
import cv2
import time
cv2.namedWindow("Hawk Eye", 1)
capture = cv2.VideoCapture(0)
capture.set(cv2.cv.CV_CAP_PROP_FRAME_WIDTH, 800)
capture.set(cv2.cv.CV_CAP_PROP_FRAME_HEIGHT, 600)
x_offset=y_offset=50
arrows = cv2.imread("hawk.png")
while True:
ret, webcam = capture.read()
if ret:
webcam[y_offset:y_offset+arrows.shape[0], x_offset:x_offset+arrows.shape[1]]=arrows
cv2.imshow("Hawk Eye", webcam)
if cv2.waitKey(10) == 27:
break
cv2.destroyAllWindows()
