Get worldpoints from lanedetection

Hello,

I am trying to use the LaneGraph with Lane net as input. However when the dwLanedetections from
LaneNet are received the array which should contain the worldpoints (dwLaneMarking.worldpoints) always
filled with zeroes. This causes the lane graph to fail.

We have tried to use an instance of a calibrated camera with a rig file to backproject from pixelspace to world space. We used the following code as found in this thread ([url]https://devtalk.nvidia.com/default/topic/1043877/driveworks/how-to-transform-points-from-image-space-to-world-space-/post/5302776/#5302776[/url]) until step 10.

Our question is how do we transform this ray into a worldpoint?

Hi,

That’s a duplicate to this bug: [url]https://devtalk.nvidia.com/default/topic/1048614/camera-calibration-2d-3d-reprojection-/[/url]

I know you are all waiting for the Tutorial to come out, so please be patient: Our next release is coming!

Hi Fabian,

Thanks for your quick reply. Do you have any idea when this tutorial is going to be released?

Without promising you a date, it should be somewhere in between the very end of April and mid of May.

It will be released among our DRIVE release.
