Scenario-Driven Search for Pedestrians aimed at Triggering Non-Reversible Systems

Abstract-This paper presents the results of an innovative approach to pedestrian detection for automotive applications in which a non-reversible system is used; therefore the aim is to reach a very low false detection rate, ideally zero, by searching for pedestrians in specific areas only. The great advantages of such an approach are that pedestrian recognition is performed on limited image areas-therefore boosting its timing performance- and no assessment on the danger level is finally required before providing the result to either the driver or an on-board computer for automatic manoeuvres. This system has been extensively tested on two prototype vehicles equipped with one laserscanner, one camera, and brakeby-wire technology both in Italy and Korea; this paper describes the extensive tests and shows performance measurements.

Free space detection on highways using time correlation between stabilized sub-pixel precision ipm images

Abstract — The work described in this paper has been developed in the framework of the Integrated Project APALACI- PReVENT, a European research activity funded by the European Commission to contribute to road safety by developing and demonstrating preventive safety applications and technologies. This paper describes a new method for detecting free space in front of vehicles driving on highways. The described algorithm is mainly based on time correlation and Inverse Perspective Mapping (IPM). In order to improve the system robustness and reliability IPM has been modified to achieve sub-pixel precision and a new image stabilization method specifically designed to work on structured road is also proposed. The robustness of the method will be shown describing test results. Considerations on computational power requested by the algorithm are provided. Index Terms — Free space detection, image correlation in time, inverse perspective mapping, sub-pixel accuracy, image stabilization. I

The BRAiVE Autonomous Ground Vehicle Platform

The interest in having an autonomous vehicle platform is driven by the long term objective, aimed by many research centers, of changing the transportation system world to move people in a safer and more efficient way. The BRAiVE vehicle presented in this paper is designed for this goal and with the idea of reaching it trough a series of steps, each one introducing more advanced systems and more complex levels of automation. A section describing the state of the art in this field introduces the paper showing the features of other similar projects around the world and pointing out BRAiVE's innovations. The paper focuses on the technical aspects involved in this project. Starting from the design choices, such as sensor placement, coverage or actuators performance, going trough development issues and solutions adopted to reach a high integration level for preserving the external look together with good ergonomics for the interiors. Conclusions collect the demonstrations in which effectiveness and the versatility of the vehicle has been shown
