D3-3P-TDA3X-SK: Lane Detection algorithm

Part Number: D3-3P-TDA3X-SK

Hello

I am using TDA3x RVP SoC.

I want to develop lane Crossing detection use case using this SoC in Vision SDK. The Input capture camera used is ISS (OV10640 Sensor).

I have seen a default use case in Vision SDK on lane detection-

" 1CH VIP capture (HDMI) + Lane Detect (DSP1 + EVE1) + Display"

But this is using VIP (HDMI) capture. I have taken this as the reference and developed my own use case using the following links (for lane detection using ISS capture)-

IssCapture -> IssM2mIsp -> IssM2mSimcop -> Dup -> Merge_alg

Dup -> Alg_ImagePreProcess (EVE1) -> Alg_ImgPyramid -> Alg_LaneDetect (DSP1) -> Merge_alg -> Sync_alg (DSP1) -> Alg_ObjectDraw (DSP1) -> Display_Video

IssM2mIsp -> Alg_IssAewb

GrpxSrc -> Display_Grpx

The use case which I have developed is working. The problem with the usecase is that it is detecting only left lane crossing and showing the warning on the display. It is not detecting right lanes or right lane crossing.

My doubt is whether the default use case present in Vision SDK for lane crossing detection is designed only for left lane crossing (that is suitable for few countries) or a generalized one that can be implemented on all countries following different traffic rules.

    There is no such design restrictions. Please refer the appendix in user guide (LaneDetection_DSP_UserGuide.pdf) it provides the configurations with some images. so make sure that these parameters are rightly configured for your requirement. Mainly focus on below parameters configuration

    1. departThetaLeftMax and departThetaRightMax
    2. departThetaLeftMin and departThetaRightMin
    3. departRhoLeftMax and departRhoRightMax
    4. departRhoLeftMin and departRhoRightMin

    Thanks,

    Thank you for your reply.

    I have referred the user guide for lane detection and changing the parameter values.
