TDA3XEVM: Lane Detection Algorithm Calibration

Pradeep Karunakar

Part Number: TDA3XEVM

Dear team,

1.For calibration Lane Detection algorithm we have followed User guide located in PROCESSOR_SDK_VISION_03_07_00_00\ti_components\algorithms\REL.200.V.LD.C66X.00.03.00.00\200.V.LD.C66X.00.03\modules\ti_lane_detection\docs\LaneDetection_DSP_UserGuide.pdf.

Lane Detection was not smooth as we varied various parameters such as departThetaLeftMin,departThetaLeftMax,departRhoLeftMax ,etc for road with the camera holdings for different heights.

Please let us know how to obtain current values (live) Theta and rho (theta1 ,theta2 ,Rho1 and Rho2) values printed on the consoles .This will help us to calibrate the road for Min and maximum values for theta1 ,theta2 ,Rho1 and Rho2 for different heights.

Regards,

Dear team,

1. Any update ?

2. Do we have some calibration tool/ Reference tool to update the Theta and rho (theta1 ,theta2 ,Rho1 and Rho2) values for any given road?

Currently we are not using CCES . Please let us know the above points how we can resolve?

Regards,

Pradeep K

Dear team,

Please respond the above query..

The theta information is provided in terms of bin and not in degrees .How we can correlate the lane detection while setting the road map information.

We don't have a way to dump the running value of theta1 ,theta2 ,Rho1 and Rho2. These are not exposed by the algorithm library and we are not in a position to modify it. So, unfortunately, you need to use hit and trial to tune your parameters.

Thanks,
with Regards,

Pramod
