TDA4VM: Online/Auto camera calibration

Hello, Experts,

          During the development,  we refer the demo "Surround View Calibration", to calibrate the cameras .

https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-jacinto7/latest/exports/docs/vision_apps/docs/user_guide/group_apps_srv_demos_app_srv_calibration.html

          as this sample, we can only calibrate the cameras in the specific environment (we need to use the calibration pattern such as )

      But, is there any auto/online calibration for TDA4, so that we can  just drive the vehicle on the road for some time and finished the calibration?

       (In some hardware or PC side, sparse optical flow or networks can do a similar job. However, in TDA4, lk optical flow runs too slow.  Based on this situation  , is there any  recommended solution ?)
