I have some questions about the "FX3 3-D Imaging Demo", the demo said "two monochromic image sensors that are self-synchronized", the self-synchronized is how to achieve it? We want to achieve binocular automatic adjustment of brightness and exposure to meet more application scenarios, can open AGC / AEC will lead to two cameras are not synchronized, I would like to ask how to solve this problem in the demo?

You need to make sure that the sensors are synchronized as the GPIF will be sampling the data from both the sensor at the same FV/LV. We have briefly described this condition for synchronization in AN75779 application note, section 9. Some sensors do provide a sync pin which can help to synchronize 2 sensors to give data at a signal FV/LV

Thank you for your reply, our program is the same as your suggestion, can achieve two sensors synchronized, but after this there are some problems: because AGC / AEC have been closed, sensors in different light intensity of the adaptability is not very good, Need to be adjusted manually. Is there a way to achieve automatic exposure and automatic gain in this scenario?

   

Thanks

We have provided AN75779 and an sample firmware with it. "FX3 3-D Imaging Demo" will need slight modification as per section 9.1 of AN75779. Please go through this section and let us know if you have any question.

 Nishant,

   

Thank you. It helps a lot. May I have the part number for the daughter board with 2 image sensor that can interface  120-pin J7 on FX3 DVK demo board? I want to evaluate it while waiting for customized hardware design.

   

Regards,

   

Kelly
