Embodiments can provide a data-collection system for collecting training data for autonomous driving applications. The system can include an on-vehicle light-detection—and—ranging (lidar) unit mounted on a data-collection vehicle, a roadside lidar unit, a frame-alignment subsystem, and a frame-superimposing subsystem. The on-vehicle lidar unit is to collect a first stream of frames while the data-collection vehicle is in motion. The roadside lidar unit is to collect, while remaining stationary, a second stream of frames. The frame-alignment subsystem is to align the second stream of frames collected by the roadside lidar to the first stream of frames collected by the on-vehicle lidar in time and spatial domains. The frame superimposing subsystem is to superimpose a frame from the second stream of frames onto a corresponding frame from the first stream of frames, thereby facilitating enhancement of point clouds of objects in the first stream of frames.
