Capture embedded google map image with Python without using a browser

阅读更多关于 Capture embedded google map image with Python without using a browser

I have noticed that, from Google Maps page, you can get an "embed" link to put inside an iframe and load the map in a browser. (no news here) The image size can be adjusted to be very large, so I am interested in getting som big images as single .PNGs. More specifically, I would like to define a rectangular area from a bounding box (upper-right and lower-left coordinates), and get the corresponding image, with an appropriate zoom factor. But my question is: How can I use Python to get the "pixel content" of this map as an image object? (My rationale is: if the browser can get and render such

问题 I have calculated homography ,taken out perspective transform .I am able two display two images in one window but unable to merge them.Here are my example images-> The code I am using thiscode -> cv::warpPerspective(image2,warpresult2,homography,cv::Size(2*image2.cols,image2.rows)); Mat imgResult(image1.rows,2*image1.cols,image1.type()); Mat roiImgResult_Left = imgResult(Rect(0,0,image1.cols,image1.rows)); Mat roiImgResult_Right = imgResult(Rect(image1.cols,0,image2.cols,image2.rows)); Mat

Displaying stitched images together without cutoff using warpAffine

阅读更多关于 Displaying stitched images together without cutoff using warpAffine

I'm trying to stitch 2 images together by using template matching find 3 sets of points which I pass to cv2.getAffineTransform() get a warp matrix which I pass to cv2.warpAffine() into to align my images. However when I join my images the majority of my affine'd image isn't shown. I've tried using different techniques to select points, changed the order or arguments etc. but I can only ever get a thin slither of the affine'd image to be shown. Could somebody tell me whether my approach is a valid one and suggest where I might be making an error? Any guesses as to what could be causing the
