VR180 Cameras

Just reposting this 2018 article for my own reminder for further research.

---------------------------

Lenovo and Yi have both launched 180-degree VR cameras that capture 3D videos and photos in 4K for use on Google’s Daydream platform. Google said that it is also partnering with other manufacturers including LG and Panasonic to bring other 180-degree cameras to the market, with different models sporting different features.

Google and its partners are not the first companies to tout 180-degree VR video. Californian start-up LucidCam brought its VR180 camera to market in mid-2017.

The Lenovo Mirage Camera and YI Technology’s YI Horizon VR180 Camera will hit shelves in the second quarter, and a camera from LG will be coming later this year. For professional creators, the Z Cam K1 Pro recently launched, and Panasonic is building VR180 support for its just-announced GH5 cameras with a new add-on.

VR180 cameras are designed to allow users to capture special moments in crisp 3D VR, allowing people to capture their memories in stunning immersive detail. By capturing the action in 180- degrees as opposed to 360-degrees, these devices have the advantage of putting the shooter in control of what footage is captured, while also lightening the load by not recording unnecessary content.

Footage captured on VR180 cameras can be viewed and shared in either 2D or 3D. A VR headset, including even a Google Cardboard headset, is all that’s required to experience footage in VR.

Lenovo Mirage Camera is just over 4″ long and 2″ tall, and weighs less than 5 ounces. The device has dual 13MP cameras for 3D, or stereoscopic, recording. Lenovo launched the device at CES along with its new VR headset.

Yi Horizon uses an Ambarella H2V95 chipset supports 5.7K video and photo capture. With the accompanying YI 360 App, users can easily share their 3D VR video. The integrated 2.2” retina touchscreen supports a flip design.

Build hardware synchronized 360 VR camera with YI 4K action cameras

YI 4K Action Camera is your perfect pick for building a VR camera. The camera boasts high resolution image detail powered by amazing video capturing and encoding capabilities, long battery life and camera geometry. This is what makes us stand out and how we are recognized and chosen as a partner by Google for its next version VR Camera, Google Jump - www.yijump.com

There are a number of ways to build a VR camera with YI 4K Action Cameras. The difference being mainly how you control multiple cameras to start and stop recordings. In general, we would like all cameras to start and stop recording synchronously so you can easily record and stitch your virtual reality video.

The easiest solution is to manually control the cameras one-by-one. It is convenient and quick however it doesn’t guarantee synchronized recording.

A better solution therefore is to make good use of Wi-Fi where all cameras are set to work in Wi-Fi mode and are connected to a smartphone hotspot or a Wi-Fi router. Once setup is done, you should be able to control all cameras with smartphone app through Wi-Fi. For details, please check out https://github.com/YITechnology/YIOpenAPI

Please note that this solution also comes with its limitations. For instance, when there are way too many cameras or Wi-Fi interference happens to be serious, controlling the cameras via smartphone app can sometimes fail. Also, synchronized video capturing is not guaranteed since Wi-Fi is not a real-time communication protocol.

You can also control all cameras with a Bluetooth-connected remote control. The limitations however are similar to that with Wi-F solution.

There are also solutions which try to synchronize video files offline after recording is finished. It is normally done by detecting the same audio signal or video motion in the video files and aligning them. Since this kind of the solutions do not control the recording start time, its synchronization error is at least 1 frame.

HARDWARE SYNCHRONIZED RECORDING

In this article, we will introduce a solution to solve synchronization problem using hardware. We do this by connecting all cameras using Multi Endpoint cable where recording start and stop commands are transmitted in real-time among the cameras, in turn, creating a high-resolution and synchronized virtual reality video.
