[Elphel-support] video camera for drone project

[Elphel Support]

Hello Maria,

The camera uses mt9p031 sensors, this datasheet http://www.onsemi.com/pub/Collateral/MT9P031-D.PDF lists some of the frame rate/resolution combinations - camera supports all what sensor can provide.
With latency with default firmware camera sends acquired frame immediately after it is acquired - when the frame sync pulse comes from the sensor, it starts sending the previous frame.
It is possible to reduce the latency even more, but that will require some software development and custom software on the receiving side as for sending standard files you need to know file size, and the file size is available only after the full frame is compressed.

The FPGA code that acquires and compresses image frames has latency of 18 scan lines plus under 1000 pixels - this is the lag between the pixels acquired from the sensors and compressed data is stored in the system memory. So it is possible to send it  not waiting for the full frame to be compressed.

Oleg will reply you about the power and weight, but yes - it is possible. And with the same weight you can have up to 4 simultaneous sensors operating.

Hello 


We are looking for a camera with the following characteristics:


 
Desired Camera and Communications Specifications
 
Communications: Wireless operating at 5 GHZ, with transmitter built-in or external HDMI transmitter
 
to be processed /displayed in  local computer.
 
Resolution Video: 1080p at 30 frames/sc
 
 System Communications Latency ( From Camera to Computer Display) : <  order of ms
 
Range : >50 feet
 
View angle: > 120 
 
Power: Battery operated with duration of an hour before recharged
 Weight: < the minimum as possible < 1pound


Do you have a camera that meet this characteristics? The more critical parameter is the latency and we are open to suggestion for the communications scheme.


Thanks,


Maria C. Gonzalez
