TDA3MV: surround view on TDA3xx

Part Number: TDA3MV

Hi Expert,

I'm developing a custom tda3x board on TI-RTOS Vision SDK v03.04.

Vision SDK Usecases
    2: Multi-Camera LVDS Usecases
        7: OV10635 & UB964 4CH CSI2 Capture + Display
After the modification, I can see the 4-channel screen when running it.

Capture and Display link make the same modification, try to carry out:
    8: OV10635 & UB964 4CH CSI2 Surround View (DSP) + Display (HDMI)

The result is as shown in the figure below. No camera image is seen!
The default is HDMI, and it is modified to LCD: 1280 * 720.

Check the link, it seems there is no problem with capture link?


How can I display the camera image??

Thanks in advance.

    The surroundview output frame resolution of the use case doesn't look correct.

    It prints 880x1080 on the screen while your display resolution is 1280x720.

    Please double check the camera image resolution, surroud view algorithm image resolution, and graphic link image resolution and make sure these settings are consistent.

    Regards,
    Stanley

    My inspection configuration is as follows:

    ‧ camera image resolution:
    #define CAPTURE_SENSOR_WIDTH (1280)
    #define CAPTURE_SENSOR_HEIGHT (720)


    ‧ surroud view algorithm image resolution:
    Void chains_csi2CalSVStandalone_issRsz_SetAppPrms
    ChainsCommon_SurroundView_GetSrvOutputResolution(
        pObj->chainsCfg->svOutputMode,    // 0
        &svOutWidth,                                     // 720
        &svOutHeight);                                   // 960


    ‧ graphic link image resolution:
    ChainsCommon_SurroundView_SetGrpxSrcPrms(
        &pUcObj->GrpxSrcPrm,
        displayWidth,                                      // 1280
        displayHeight,                                     // 720
        pObj->chainsCfg->svOutputMode);

    Is the item I checked right?

    Which one needs to be adjusted?

    The output of SurroundView is not to the left,
    I tried to adjust the posX/posY below but it didn't change?

    ChainsCommon_SurroundView_SetDisplayPrm(
        &pUcObj->Display_svPrm,
        NULL,
        NULL,
        &pUcObj->Display_GrpxPrm,
        displayWidth,                                     // 1280
        displayHeight);                                   // 720

    if(pSvDisplay)
    {
        ...
        pSvDisplay->rtParams.posX = (float)svPosX / displayWidthScale;    // 0
        pSvDisplay->rtParams.posY = (float)svPosY / displayHeightScale;    // 0
        pSvDisplay->displayId = DISPLAY_LINK_INST_DSS_VID1;

    Thanks.
