I need to collect large data from sensors and pass those data to computer via USB and using this data I need to make a bitmap Image.Can I use Arduino Due for this.Sensors count is >70.
Yes and no, it depends...depends on the detail of what the heck you want to do. You need to provide a lot more detail than that.
And you shouldn't cross post as well. So when you do provide the details only do it in one of the threads, in fact delete one of them if you can.
Well I am making a touch screen architecture, so I want to place sensors around the display. If there is touch action some of sensors will be on and others will be off. so i need this data from sensors with these data i will create series of bitmap images on which image processing is done.
So the bit map won't be very large it seems, that should be ok, what about the "sensors" how are you going to do that. A matrix of light beams?
