TDA2EG: SRV Photometric alignment adjustment Issue

SRV Photometric alignment algorithm & code Issue

Hi all,

     I came across the similar issue like "SRV Photometric alignment algorithm adjustment issue" raised by xuanbo. I studied the TI codes and didn't find any Photometric alignment algorithm detail related codes except a few parameters as follows:

pAlgCreateParams->PAlignTuningParams.beta = (1<<7);
    pAlgCreateParams->PAlignTuningParams.inTh = 6400; // 65536; //800; 1600;
    pAlgCreateParams->PAlignTuningParams.nAnPts = 5;
    pAlgCreateParams->PAlignTuningParams.nUpGn = 10;
    pAlgCreateParams->PAlignTuningParams.nUpTv = 10;

/*** codes file:PROCESSOR_SDK_VISION_03_06_00_00/vision_sdk/apps/src/rtos/alg_plugins/surroundview/pAlignLink_algPlugin.c  ***/

     There is not any detail annotation, so I don't know the Photometric alignment algorithm details and how does it work. Do you have some articles or references to show me the algorithm details and how & where to develop related TDA codes? If I want to refine Photometric alignment algorithm,  which codes I should change and how to guarantee it work?

     Looking forward to your reply!

     Best regards,

    Hi Yongi,

    Unfortunately, I do not have anymore information on this and this algorithm is deprecated.

    Hi Shashank,

        Thanks for your reply! We are developing SRV feature now, we have found method to solve geometric stitching seamless, but do not know how to embed photometric stitching seamless algorithm into TDA codes. If you have deprecated photometric alignment algorithm, how do you solve solve geometric stitching seamless of SRV?Or is there some API in TDA codes we can develop our photometric stitching seamless algorithm of SRV?Our test  of SRV  is as follows:

        Can you tell me how to solve this problem?Look forward to your kind reply.

        Best regards,

    Yongji

    Hi,

    We only provide reference demo software and expect our customers to develop their own algorithms. There are also several 3rd parties who can license algorithms for a certain licensing fee which is paid by the customer and typically requires an agreement between the customer and the 3rd party.

    At this point, we don't have any plans to develop a photometric correction algorithm.

    Regards
