Two new ways to automatically aim the camcorder

In the previous article, we promised to talk about two new ways to implement automatic pointing of a PTZ camera at an active participant in the meeting room. This functionality significantly revives video conferences and eliminates the need to manually switch the position of the video camera.

Recall that in the traditional way the task of auto-guidance is implemented using the congress system . This solution has already been tested by us and implemented in a large number of projects . In this embodiment, the microphone consoles are used not only for high-quality sound capture, but also for linking the coordinates of the camera's “presets” to the position of the microphones in the room.

Unfortunately, not all meeting participants welcome the microphones on the “goose neck”, but everyone wants to leave the functionality of the automatic guidance of the PTZ camera. In general, it made us think about solving the problem. And we found two interesting options. Naturally, you will not have to buy a Polycom Eagle Eye Director for this, as other integrators would suggest to you :)

First way

So, the first method, let's call it semi-automatic, is based on the use of special "clickers". The advantage of this method is the ability to use speakerphones or a microphone array in a meeting room, which allows speakers not to think about where to speak, voice will be captured in any direction. In general, no “goosenecks”. To do this, use the ready-made kit, which consists of the following components:

In practice, the "clickers" need to follow and introduce regulations for their use. For example, on each clicker, specify the preset number of the PTZ camera to which it is “tied”, in the same way, mark the places at the table. The process of setting up the central unit is trivial and takes about 10 minutes for 8 “clickers”. The work of the solution can be viewed on the video below.

In our case, a prototype is used, so the appearance of the "clicker" is far from ideal. We would like to know your opinion on this decision. Are you interested in it? Would you use it in your meeting rooms during video conferencing? Write in the comments!

Second way

The second method is more convenient, reliable and innovative! :) It is fully automatic and does not need to use separate devices to bind the speaker to the space in the meeting room.

Guidance of a PTZ camera occurs by voice, namely, by “beam” or “rays”, which is built by an array of microphones, highlighting the speaking participants in the room. It's all like adults, only cheaper! The hardware manufacturers of video conferencing systems (Polycom, Cisco, etc.) have similar solutions , but their cost is measured in several tens of thousands of dollars.

We had to write a special software and spend a lot of time on its calibration in order to make this method real. So, we present you UnitKit Medium , which consists of the following components:

As a result, it works as follows: the Condor determines the direction to the speaker, the software associates it with the vector to the nearest sitting position and issues a command to install the corresponding “preset” to the PTZ camera.

Now we are working to create a convenient interface for the program. The program will be supplied free of charge as part of the UnitKit Medium kit. The following video clip shows how it works.

Again, we are interested to know your opinion: do you like this method of autoname? Are you ready to use it in your projects?
