Hi all,
I got some doubts about the DRIVE AGX Xavier ISP units. From the documentation, I extracted that it has 2 ISP units (ISP0 and ISP1). But, I got the following questions in regards this topic:
Is there 2 ISP units on each Xavier_A and Xavier_B, so in total the DRIVE AGX Xavier has 4 ISP units?
The ISP units on Xavier_A are independent of the ISP units on Xavier_B?
Accordingly to the documentation the ISP0 is intended for Human Vision and the ISP1 for Machine Vision. What implications has that ISP1 is intended for Machine Vision?
Thanks for your answer. The documentation doesn´t specify any detail about two simultaneous outputs of the single ISP HW engine.
I still have some unresolved doubts. Based on this NVIDIA devtlak post the ISP0 output is intended for Human Vision and the ISP1 output for Machine Vision. What implications has that ISP1 output is intended for Machine Vision?
As mentioned in this NVIDIA devtalk post, we got YUV output from ISP0 and RGBA output from ISP1. But, we are getting a really dark RGBA Image output from ISP1. Also, we already tested taking out RGBA from ISP0 and YUV from ISP1, in this case, we got a really dark YUV image. So, no matter the color space format taken out form ISP1, we got a really dark image.
Is that dark image output behavior expected from ISP1 output?
Is it possible to configure ISP1 output to got a similar output as ISP0?
Dark output is expected on machine vision output because of truncation of frame output to display, which takes only 8 bit of each color of the pixel. Moreover it has very little processing, no edge manipulation and any reversible function.
Maybe using 2D blit to make another copy from ISP0 output is a way to go.
