Shuntaro Tsuchiya･Yui Tanaka･Takeru Ninomiya･Hideaki Kido (Hitachi)･Kota Irie･Yoshitaka Okuyama (Hitachi Astemo)

Development of BEV　(Bird Eye View) model that integrates multi-camera images in a bird's-eye view space is in progress. However, image-based recognition is still challenging due to low ranging accuracy. This report shows that using the relative distance obtained by stereo matching techniques improves the accuracy of 3D recognition by BEV model.

Detecting surrounding traffic participants is essential for safe autonomous driving. In 3D object detection with LiDAR, false-positive objects caused by rain splatting noise lead autonomous vehicles to unsafe path planning. This research proposes robust 3D object detection method against false-positive objects to rain splatting noise.

To achieve safe autonomous driving, self-localization is essential. This study proposes a matching method that retains the features of LiDAR point clouds in a Pillar structure and converts them into pseudo-images, using deep learning to estimate the vehicle's position as a likelihood distribution. The proposed method aims to achieve more robust localization compared to conventional point cloud matching methods.

Riku Nikaido･Keigo Hariya･Keisuke Yoneda･Naoki Suganuma (Kanazawa University)

LiDAR is widely used in autonomous driving perception and as an infrastructure sensor in urban environments. In this paper, we simulate a stationary LiDAR system specialized for pedestrian detection using CARLA. As a detection method, we leverage multi-frame 3D point clouds for object detection. Furthermore, the study aims a robust detection model capable of accurately identifying pedestrians in sparse point cloud data.

Development of ultrasonic transmission simulation to predict the effect of sonar false detection

Motoyasu Ukai･Takaaki Nakamura (Aisin)

High-precision sensing technology is essential to realize autonomous driving and autonomous parking. AEB (Automatic Emergency Braking System) detects obstacles using ultrasonic sonar, but false detections occur due to the influence of surrounding vehicle parts. In this study, we report on our efforts to develop CAE technology that can predict sensor signals when installed in a vehicle and judge whether they are good or bad.
