Acquisition System

The system image of nvidai xavier will be available soon.

Manufacturing Designs

The assembly body is meant to hold the LiDAR and the camera in place so that the extrinsic calibration results can be reused, which can be readily done by manufacturing factories using open source manufacturing designs.

Data orgnization

The data is organized as the following readme for each scene.

Datasets

Crossroads Scene

We collected 3D dynamic data of traffic scenes by 4 slave nodes set up at the four corners of a street crossroad, where many vehicles and pedestrians moved across the scene. We provided 4, 000 frames with 3D bounding box annotations of cars, cyclists, and pedestrians in the central area of the crossroad.

Multi-person Scene

To evaluate the performance of long-term objects tracking, we collected data of multiple persons moving for a long time in the plaza and rarely leaving, for 1200 frames in the day and 1200 frames at night. The persons are free to move and interact with others, which results in a lot of occlusions and intersected trajectories, causing great difficulties for single-view data.
