TDA4VH-Q1: VIPC configuration for fisheye camera

Alex Egudkin
Prodigy 20 points
Part Number: TDA4VH-Q1
Other Parts Discussed in Thread: TDA4VH

Tool/software:

Hi, 
We are working with the TDA4VH evaluation board (J784S4) with SDK version  09.02 

In our project we need to run inference on images arriving from fisheye like camera, but first we need to run Demosaic and Distortion correction operations on it (prior to running the inference itself) 
thus, we are trying to utilize the VPAC accelerator on the board to help us with the tasks above and would really appreciate your help in the process: 

The fisheye surround camera we are using is: 

Manufacture: Continental 

Model: SVC 220 

Image Resolution: 1920x1280 pixels 

Data format: 12 bits per pixel 

The images are transmitted in RAW BGGR color format. 

As far as we understood we might need to use TI DCC tool in some manner and we already managed to get the tool and install it on our local PCs, and we are stuck at this point. 

Thank you in advance for your help. 

Alex.

    Hi Alex,

    Both of these operations, ie RAW to YUV conversion and distortion correction could be done in VPAC modules. What information are you looking for ?

    Hello Brijesh, 
    Thank you for your answer, and sorry for my delay response, I was on vacation. 
    We know that VPAC can be used for both Demosaic and Distortion Correction operations (we already implemented a solution for other project we had doing just that for a pin hole front camera). 
    In our current project we use a different set of cameras (as I specified above Surround fisheye cameras) and we tried to work with DCC tool to create the needed XML configuration files for the VPAC accelerator and later to configure the VPAC to use that configuration and run the Image processing operation and we failed, in the following locations: 

    1. DCC didn't complete his processes clearly, we received several errors in the process, and saw invalid images in the preview screen. 

    2. The VPAC failed upon initialization of VxGraph when we tried to use the generated configuration from the previous steps. 

    So, we understand that we need help with both those steps.

    Hello Alex,

    Can you please share the error messages from both A72 and R5F? This will help us to identify the issue in the configuration.

    Hi,

    As the error says, the H3A parameters seem incorrect. Please h3a xml file for the review.
