Multiple usage of RealSense in one area.

[ADzhu]

Hello, we are looking for depth sensor which can be used with area overlapping with the same sensor.

The main Idea to create big interactive table.

RealSense devices are based on IR-projector and IR-receiver.

Probably it works incorrectly when the same area is highlight by multiple IR projectors.

In our situation about 15% of area could be highlight by 2 devices.

I have 2 questions.

1.

Could you, please, describe how does it influence on the accuracy, is it decrees accuracy only in twice highlight area, or

in all scanning area ?

2.

Does any of RealSense devices allow to add highlighting mask to the IR-projector, so we could

shut down it locally only in overlapped area ?

1. The RealSense 400 Series actually works excellently when the fields of view are overlapped. The cameras do not interfere with each other, and more comprehensive depth data is captured because the overlapping fields mean that there is redundancy in the data.

2. The RealSense SDK 2.0 software used by the 400 Series allows an auto-exposure Region Of Interest to be defined on an image. In this region, the intensity of pixels is averaged and then the SDK tries to maintain the value at a pre-defined setpoint. This may provide the highlighting that you need.
