Because Terminals are cool~ Tired of websites plagued with heavy JavaScript, ads and consent pop-up? There were simpler times on the internet when everything was text-based. A time where cathode-ray tube displayed 80 by 24 blocks of glowing and colorful characters. But I don’t wanna to learn those pesky terminal escape characters! Don’t worry, Python comes to the rescue. It has…

Tips to share a movie over internet and watch it together with someone else. Do you miss watching a movie with friends or family? Isn’t it great when you can pause a movie and discuss about it? If you try to share your desktop, running a movie player, inside your…

Using simple OpenGL 3D view rotation Previously Do you remember inastitch, the video stitcher for live stream? Faster video stitching with OpenGL Stitching with OpenCV is all nice, but what if you wanted to do the same with OpenGL?levelup.gitconnected.com Quick summary: inastitch merges three live video streams into a single wider stream. In this previous project, homography of the input streams was simply achieved in 2D by warping pixels using an OpenGL pixel…

As low as 100µs delay can be reached with stock Raspberry Pi and no custom hardware. Examples use-cases for synchronized video streams are: image stitching for panoramic photo/video, or image blending for example: HDR or low light imagery stereovision for 3D reconstruction and depth sensing applications multi-camera tracking for example…

Scanning the streets might not need an expensive setup. Do you remember the 8-camera video stitcher project? Eight Raspberry Pi and corresponding camera are connected on a local network and synchronized to capture 360° panoramic images. What if you let it grow taller and attach a bike to it?

Stitching with OpenCV is all nice, but what if you wanted to do it all in hardware on GPU with vanilla OpenGL? Introduction OpenCV comes with an advanced sample implementation which produces great results on still images, however, using this program on every single frame of video streams is unsurprisingly extremely…

PTP on Raspberry Pi, it’s apt install linuxptp and done, right? Maybe not. Here are some tips to run it better than the default settings. This article is part of a series about inastitch. In this project, clock synchronization is critical for frame capture alignment. It all started with this…

You have cool project idea and you want to make a prototype more compatible with the automotive world? Here are some design choices for you… Of course, some old-school hard real-time C code running bare metal on a microcontroller would always rekindle the heart of automotive engineers, but for quick…

What would it take to make your own video footage at 360 degrees? The answer: a bunch of cameras and some open source software. Let’s try… First we need to talk about image stitching. With no surprise, OpenCV has a great sample implementation for this and often gives impressive seamless…
