Most of this content isn't covered until Terms 2 & 3, but it's surprisingly relevant.
That's oddly worded. The wording makes it sound like it's the code from numerous different cars in the challenge, and not just Stanford's entry, but the site wording and the source structure itself look to be a single system.
Then again, the code is from 2011, so I guess the past tense is somewhat justified...
Not for use at high altitudes. From "perception/trafficlights/src/traffic_light_view.cpp:
sprintf(lightBuffer,"%f %f %f", currPose.latitude, currPose.longitude, currPose.altitude);
Yes, it's debug code.The perception end of things is mostly digesting the point cloud from the Velodyne LIDAR. There's vision code for traffic light recognition, but I haven't found other vision code yet.
