Kamerabasierte Bewegungsanalyse aller Verkehrsteilnehmer für automatisiertes Fahren – Camera-based Motion Analysis of Road Users for Automated Driving

This project addresses motion estimation of road users, e.g., cars and pedestrians, using monocular image sequences. To achieve that, panoptic segmentation is applied to each camera image to extract object instances of road users. Then, 3D information (position, orientation, and shape) of detected road users is estimated. Detected object instances are associated across frames by fusing their spatial consistency in 2D and 3D. The result is the motion of all detected road users, which is fundamental for the planning phase of automated driving.

Dieses Projekt wurde mit Mitteln des Europäischen Fonds für regionale Entwicklung gefördert. – This project was partially funded by the European Fund for Regional Development.

For the products VooCAT/CineCAT, various algorithms for camera calibration, tracking, structure from motion, and video segmentation are developed. The basis for the scene estimation is the usage of corresponding image features which arise from a 3D structure being mapped to different camera image planes. By using a statistical error model which describes the errors in the position of the detected feature points, a Maximum Likelihood estimator can be formulated that simultaneously estimates the camera parameters and the 3D positions of the image features.

The camera path, the video segmentation, and the reconstructed scene are essential for the integration virtual objects into the video. The point cloud is used for 3D measurements, such as distances to or between different objects of the scene.

For the estimation of motion models of moving objects in video, a motion segmentation technique is utilized. Motion segmentation is the task of classifying the feature trajectories in an image sequence to different motions. Hypergraph based approaches use a specific graph to incorporate higher order similarities for the estimation of motion clusters. They follow the concept of hypothesis generation and validation.
Our approach uses a simple but effective model for incorporating motion-coherent affinities. The hypotheses generated from the resulting hypergraph lead to a significant decrease of the segmentation error.
