We focus on delivering realistic dataset for training driving models. Drive360 is recorded by driving in (around) multiple cities in Switzerland. With the sensors described, we collect a new dataset Drive360. For instance, the mean reaction times for unexpected and expected human drivers are 1.3 and 0.7 s. This is also tolerable as human drivers issue driving actions at a relative low rate. The synchronization error of the CAN bus signal to our video frames is up to 10 ms. This is acceptable, as the planned route (regardless of its repre- sentation) is only needed to provide a global view for navigation. The synchronization error of the maps to our video frame is up to 16.6 ms. Our cameras, however, provide good photometric image quality and high frame rates, at the price of moderate synchronization error. We acknowledge that a camera which can be triggered by ac- curate trigger signals are preferable with respect to synchronization error. If the vehicle is at a speed of 100 km/h, the error due to the synchronization for vehicle's longitudinal position is about 23 cm. The resulting synchronization error for the video frames is up to 8.3 milliseconds (ms), i.e. During all recording, the internal clocks of all sensors are synchronized to the GPS clock. For this we devised an automatic procedure that allows for synchroniza- tion to GPS for fast dataset generation. ![]() The correct synchronization amongst all data streams is of utmost importance. ![]()
