nona_gui a version of nona with simple GUI progress dialogs, similar to the windows version of PTStitcher.fulla correction of barrel distortion, chromatic aberration and vignetting.nona_gui, nona with a graphical progress bar.nona – a simple stitcher that does geometrical and photometric distortions to photos and writes the output to image files.Hugin – the graphical user interface front end.ACM, 2003.The following tools are part of the Hugin suite: In ACM Transactions on Graphics (ToG), volume 22, pages 277–286. Graphcut textures: image and video synthesis using graph cuts. Vivek Kwatra, Arno Schödl, Irfan Essa, Greg Turk, and Aaron Bobick. Look into the releases section for the pre-compiled binary raspivid-inatech. Step5: Encode videoĪssemble all stitched JPEG files into a video again and encode it back to H264. Rebuild stitching_detailed with the matrices selected in the previous step as hardcoded transformation, and stitch all the video frames. Only one set of matrices is selected for the next step. Each matching frames of the stream will have different matrices. In case of success, each frame has two matrices: the camera matrix (aka “K”) which encodes the camera characteristics (e.g., focal, aspect ratio), and the rotation matrix (aka “R”) which encodes the camera rotation.Īs explained in the beginning of this article, stitching will assumes a pure rotation, which is not the case in real life. Depending of the feature algorithm (e.g., SURF, ORB, …) and the details visible in the overlapping area of the frames, matching will succeed or not. Run OpenCV stitching_detailed on some matching frames to find transformation matrices. Step2: Align framesĬopy video streams, split video in single JPEG files along with capture timing information in text file (i.e., modified raspivid PTS file).įind the matching frames. Power on, let PTP stabilize (might take a few minutes), start recording on each Raspberry Pi. While recording the video, the network is only used for PTP and no other communication is made.

Even though the Raspberry Pi Ethernet lacks the dedicated hardware for high accuracy PTP clocks ( hardware timestamping), it still often achieves a clock synchronization well under 1ms using PTP in software mode. The software PLL changes the camera framerate at runtime to align frame capture time on the Linux system clock.Īll eight system clocks are synchronized over Ethernet using PTP (which stands for Precision Time Protocol).
