image-stitching

问题 I am trying to stitch about 50 images(all in the same 287x287 size) together. Specifically, there should be 25 images on the top row and 25 images on the bottom row, and there also exists a small distance between each two images. I met two difficulties during my attempts: First problem is that there are 25 images in a folder with their name 'prefix-70',...,'prefix-94' while other 25 images in another folder with the same name 'prefix-70',...,'prefix-94' . I do not know how to them in Python

问题 I am doing image stitching in OpenCV (A panorama) but I have one problem. I can't use the class Stitching from OpenCV so I must create it with only feature points and homographies. OrbFeatureDetector detector( minHessian ); std::vector<KeyPoint> keypoints_1, keypoints_2; Mat descriptors_1a, descriptors_2a; detector.detect( img_1, keypoints_1 , descriptors_1a); detector.detect( img_2, keypoints_2 , descriptors_2a); //-- Step 2: Calculate descriptors (feature vectors) OrbDescriptorExtractor

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 7 years ago . I have a very high number of small images (360x192), taken in sequence as screenshots from a DOS 2D computer game. They have decent overlap and i'd like to stitch them together into one big composite. Due to their very nature each subsequent image will fit pixel-perfect over the next or previous one. As such no

问题 I have 7 images from gopro (5 cameras in rig and one for top and one for bottom, They all are gopro camera). I want to stitch all these images together to create a 3d panorama. I have been able to stitch 5 images in Rig by using opencv stitching_detailed.cpp. Link to file: https://raw.githubusercontent.com/opencv/opencv/master/samples/cpp/stitching_detailed.cpp But I'm not sure how to stitch top and bottom (For me right now bottom is not that important but i have to do something about top).

问题 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

问题 I have run this code. It seems to be that result.png is not generated as a result: public class ImageStitching { public static void main(String[] args){ MatVector images = new MatVector(2); images.put(0,cvLoadImage("sample1.png")); images.put(1,cvLoadImage("sample2.png")); IplImage result = new IplImage(null); int status = stitcher.stitch(images,result); if( status == stitcher.OK ) { cvSaveImage("result.png", result); } result = cvLoadImage("result.png"); final CanvasFrame canvas = new

问题 I'm using OpenCV 3.2 and I have a Stitcher set up to stitch two images. The stitching works great. But once it is complete I want to be able to determine the mapping from a point in image A to the corresponding point in image B. I don't care how the images are laid out in the panorama, I just need to be able to transform from (x_A,y_A), the coordinates of a point in image A, to (x_B, y_B), the coordinates of the corresponding point in image B. How do I get that mapping out of OpenCV using the

问题 I use phase correlation for image stitching and it gives good results for most part of my test data. I just stitiching pairs of image left-right and top-bottom(only shift) But there is some strange behaviour. First strange coordinates, I must convert coordinates //if L-R pt.x= src->width-maxloc.x; pt.y= src->height-maxloc.y; if(pt.y>(temp->height/2)) pt.y= -(maxloc.y+1); //if T-B pt.x= src->width-maxloc.x; pt.y= src->height-maxloc.y; if(pt.x>(temp->width/2)) pt.x= -(maxloc.x+1); Then usage of

问题 I am using this code for image stitching with JavaCV on Android: public void ImageStitching() { Stitcher stitcher = Stitcher.createDefault(false); MatVector images = new MatVector(2); images.put(0,cvLoadImage("sample1.png")); images.put(1,cvLoadImage("sample2.png")); IplImage result = new IplImage(null); int status = stitcher.stitch(images,result); if( status == Stitcher.OK ) { cvSaveImage("result.png", result); } } But when I execute it, the app crashes and the log shows the following error:

问题 I am trying to stitch a panorama using mobile phone camera with an attachable 170 degree wide angle lens. The resulting photo is distorted (fisheye). I understand that to stitch these photos using Stitcher::stitch(InputArrayOfArrays images, OutputArray pano) they must be undistorted first. First, I did the undistort(InputArray src, OutputArray dst, InputArray cameraMatrix, InputArray distCoeffs, InputArray newCameraMatrix=noArray() ) and save the results to jpg files. Then, I read the jpg
