Understanding Indirect Time-of-Flight Depth Sensing

Are there any higher than VGA quality ToF sensors? Azure Kinect is not cutting it for us.

We'd like to do real time, full 360 depth capture of actors, but all of the sensors we've found are poorly suited for this task.

We might have to rig up our own optical system and use FPGAs to run them...

Microsoft licensed their sensor to Analog devices, and you can buy the mega-pixel iToF sensor and build a iToF camera. https://www.analog.com/en/products/ADSD3100.html?icid=ToF-ad...

Or build a camera with multiple sensors capturing different FoVs.

Samsung have published papers on a 1.2MegaPixel ToF sensors, but currently only have a VGA sensor available. https://ieeexplore.ieee.org/abstract/document/9365854 https://www.samsung.com/semiconductor/minisite/isocell/visio...

How are Analog Devices selling these chips? Like Sony with Heavy NDA? Or these will be regular catalogue parts in the future?

Im guessing like Sony, it's hard to support such chips because of the underlying complexities. Melexis has open datasheets and can purchase individual sensors off mouser.

Interesting! I was completely unaware of these. Thanks for the info.

I'm glad to see we're steadily climbing in terms of sensor resolution. We're not anywhere close to 4K 120Hz sampling, but the field is progressing.

There's nothing stopping us from doing offline processing for our workflow, I suppose.

At those resolutions and frame rates multiview stereo is probably your best technology for the moment.
