Unique to RICOH R technology is the stitching of video within the camera in real time to the Equirectangular Projection Format, which is the standard format for fully spherical images. The camera records onto a micro SD card, which enables the body to be extremely thin and lightweight. This image is 3D CG for illustrative purposes and may differ from the actual product.

Connect and share knowledge within a single location that is structured and easy to search. I need to stitch five video streams on the fly. The cameras recording the videos are mounted onto a rack side by side and will never change their relative position to one another. Homography matrices are therefore static. I'm following the approach from this github repo :. Starting from the center image, you first stitch to the left, and then stitch the remaining images to the right.

The code from that repo works, but it is painfully slow. I've been able to dramatically improve its performance factorbut it still takes 0. The slow part: Applying each result of cv2. I'm currently doing this by using the alpha channel and blending the two images, inspired by this SO answer.

It is this blending that makes the stitching slow. So my question is : Is there a way to apply the warped image to the existing panorama in a more efficient way? My full working code is in this repository.

Alpha channel is useful when your image has transparency, but here you manually add an alpha channel by converting. This channel could be used to store computation but I think you would lose performance. Here you set in the result the value of right image pixels if no value is currently set. If a value is already set, then you compute the mean of values from left and right. The computation time is divided by a factor of 1. Do this and you should divide the computation time by a factor of 4.

Image stitching or photo stitching is the process of combining multiple photographic images with overlapping fields of view to produce a segmented panorama or high-resolution image example below. Image stitching is a rather complicated application in computer vision. It is composed of several key stages, some of which involve heavy computation.

We will give an intuitive explanation of each of the key procedures below. Please follow the links provided for more technical details, and please refer to the Design Approach section for a complexity profiling of these tasks. As a first step, keypoints on the two images you want to stitch together need to be identified. These keypoints usually correspond to the most distinguish features of an image, such as corners and edges of an object.

Not only do these algorithms identify the keypoints, they will also generate a descriptor vector for each of the keypoints. These descriptors will capture information about the keypoints' location, orientation and relation to their surroundings.

Real-time panorama and image stitching with OpenCV

After keypoint detection, each image will have a set of keypoints together with their descriptor vectors. We will then need to establish matching relations between these descriptors. Most methods are based on Euclidean distance between descriptors.

For each keypoint in image 1, if its best match is significantly better than the second best match, then we consider the best match valid. Once we have establish matching keypoints between images, we want to estimate a transformation matrix H that will be used to warp the image. The algorithm basically iteratively try out different match combinations and only keep the one that is the best-fitting to the matches.

With the transformation matrix, we can project the image to the right to the plane that the image to the left is at.

This is called warping. Finally, we have the original image 1, and the warped image 2. We can stitch them together by placing pixels from both images on a blank canvas.Today we officially open-sourced the specs for Surroundour high-quality 3D hardware and software video capture system.

The open source project includes the hardware camera design and software stitching code that makes end-to-end 3D video capture possible in one system — from shooting to video processing. We believe making the camera design and stitching code freely available on GitHub will accelerate the growth of the 3D ecosystem — developers will be able to leverage the code, and content creators can use the camera in their productions.

Anyone will be able to contribute to, build on top of, improve, or distribute the camera based on these specs. Both the hardware design and software play a role in achieving a high-quality output. We've previously written about the hardware design of the camera and its importance in decreasing the processing time for the footage. Even though we use high-quality optics and machine-fabricated rigs, there is still enough variation between camera lenses that without software corrections, results are not viewable in stereo you see double vision and not 3D.

Our stitching software takes the images captured by the 17 cameras in Surround and transforms them into a stereoscopic panorama suitable for viewing in VR. This software vastly reduces the typical 3D processing time while maintaining the 8K-per-eye quality we think is optimal for the best VR viewing experience. This post goes into some depth on the rendering software we created to solve this problem, covering the goals we set, the challenges we took on, and the decisions we made in developing this technology.

Traditional mono stitching software won't solve these problems. It can apply relatively simple transforms to the source images, then blend them together at the edges, but this approach is not sufficient for stereo. It produces stereo inconsistencies that break perception of 3D and cause discomfort. Our first attempt was four pairs of cameras pointing out in a square, spaced roughly eye-distance apart.

Then we tried to stitch the left and right eye images into a seamless panorama with alpha blending, which is a basic technique for mixing images together to create a smooth transition. It looked great when pointing straight out in the direction of the real cameras, but the stereo was off at the corners.

Another issue with this approach is that as you rotate around, your eyes have to point in different directions to look at objects a constant distance away, which causes eyestrain. There are more sophisticated ways to construct stereo panoramas than basic alpha blending and stitching. One approach is to take slices of the images captured by a camera that rotates around a fixed axis. This approach produces panoramas that have proper vergence and creates more consistent perception of depth than basic stitching.

However, it cannot be applied to scenes where anything is moving. Going one step further, we use optical flow to simulate a rotating camera, by "view interpolation" from a small number of cameras arranged in a ring; this approach can capture scenes with motion, but optical flow is a challenging problem in computer vision research.

The Surround rendering code is designed to be fast so it can practically render video while maintaining image quality, accurate perception of depth and scale, comfortable stereo viewing, and increased immersion by incorporating top and bottom cameras to provide full degree x degree coverage and making the tripod pole invisible. Equirectangular projections are one technique commonly used for encoding photos and video in VR. An equirectangular projection is just a way of wrapping a sphere with a rectangular texture, like a world map.

Each column of pixels in the left or right equirect image corresponds to a particular orientation of the user's head, and the pixels are what should be seen by the left and right eyes in that head orientation.

For a given head orientation, there are two virtual eyes spaced 6. From each virtual eye, we consider a ray that goes out in the direction of the nose, and we want to know what color the light from the real world is along that ray.

That is the color we should use for the corresponding pixel in the equirectangular image. telescope: This is a framework that combines multiple frames acquired from moving cameras - GitHub - wjy/Real-time-video-stitching: This is a framework.
