A collision accident prevention method, apparatus, server, and computer program are proposed. The method can include predicting, based on data on a three-dimensional (3D) space corresponding to a caution zone, motion of each of at least one pedestrian in the caution zone and at least one vehicle in the caution zone. The method may also include determining, based on the predicted motion, a degree of risk of collision between the at least one pedestrian and the at least one vehicle. The method may further include providing a message corresponding to the determined degree of risk of collision to the at least one vehicle.

Techniques for collecting, synchronizing, and displaying various types of data relating to a road segment enable, via one or more local or remote processors, servers, transceivers, and/or sensors, (i) enhanced and contextualized analysis of vehicle events by way of synchronizing different data types, relating to a monitored road segment, collected via various different types of data sources; (ii) enhanced and contextualized analysis of filed insurance claims pertaining to a vehicle incident at a road segment; (iii) advantageous machine learning techniques for predicting a level of risk assumed for a given vehicle event or a given road segment; (iv) techniques for accounting for region-specific driver profiles when controlling autonomous vehicles; and/or (v) improved techniques for providing a GUI to display collected data in a meaningful and contextualized manner.

Implementations of the present disclosure relate to a method, an electronic device, and a computer program product for managing an inference process. Here, the inference process is implemented based on a machine learning model. A method includes: determining, based on a computational graph defining the machine learning model, dependency relationships between a set of functions for implementing the inference process; acquiring, in at least one edge device located in an edge computing network, a set of computing units available to execute the inference process; selecting at least one computing unit for executing the set of functions from the set of computing units; and causing the at least one computing unit to execute the set of functions based on the dependency relationships. With example implementations of the present disclosure, the inference process is implemented by making use of a variety of computing units in the edge computing network, thereby improving performance.

Embodiments of the disclosure provide systems and methods for determining fault for a vehicle accident. An exemplary system includes a communication interface configured to receive a video signal from a camera. The video signal includes a sequence of image frames. The system further includes at least one processor coupled to the communication interface. The at least one processor detects one or more vehicles and one or more road identifiers in the image frames, transforms a perspective of each image frame from a camera view to a top view, determines a trajectory of each detected vehicle in the transformed image frames, identifies an accident based on the determined trajectory of each vehicle, and determines a type of the accident and a fault of each vehicle involved in the accident.

Example implementations described herein involve an attribute of an inflow source that is assigned to each trajectory in the camera view, which is used for crowd analysis. The inflow source is estimated using techniques of tracking across cameras. If the inflow source is different even if the flow trajectories are the same direction, the trajectories are visualized in different styles. By using the attribute of the inflow source, it is possible to detect changes and anomalies in the crowd that were difficult to detect using the prior art.

Methods and apparatus are disclosed for producing high quality images in uncontrolled or impaired environments. In some examples of the disclosed technology, groups of cameras for high dynamic range (HDR), polarization diversity, and optional other diversity modes are arranged to concurrently image a common scene. For example, in a vehicle checkpoint application, HDR provides discernment of dark objects inside a vehicle, while polarization diversity aids in rejecting glare. Spectral diversity, infrared imaging, and active illumination can be applied for better imaging through a windshield. Preprocessed single-camera images are registered and fused. Faces or other features of interest can be detected in the fused image and identified in a library. Impairments can include weather, insufficient or interfering lighting, shadows, reflections, window glass, occlusions, or moving objects.

An apparatus and a method for providing traffic information are provided. The apparatus includes a traffic data database (DB) that stores traffic data and a processor connected to the traffic data DB. The processor generates a prediction model to predict a traffic flow and determines an appropriate data input range for a target time point in the future using the prediction model. Additionally, the processor extracts past traffic data from the traffic data DB based on the determined appropriate data input range, predicts a traffic flow at the target time point based on the extracted past traffic data and provides the predicted traffic flow as traffic information.

An information processing apparatus controls a road surface marking apparatus configured to form any road surface marking by changing light emission patterns of a plurality of light emitters provided on a road surface. In the information processing apparatus, a control unit detects, when switching from a second traffic lane through which a pedestrian is allowed to pass to a first traffic lane through which a pedestrian is prohibited from passing is executed, a user who is a pedestrian remaining in the first traffic lane after the switching. Then, the control unit causes the road surface marking apparatus to form an urging marking used for urging the user to withdraw from the first traffic lane after the switching.
