Hello team,
Sorry for the long delay happend.Actually I am in the work bench for the last few weeks.We have made some progress on this.Now,Deserializer,serializer,Cameras all are detected
We are following Barinov's approach who is CC ed here with.Also since I am little busy with some other task,I have included my colleague Anjali in this mail chain.She can share the latest log and update the progress.
Thank you guys in advance.
