Abstract: Provided are an object detection method and apparatus for an autonomous vehicle. A method of controlling a vehicle includes: detecting a surrounding environment using pieces of data on a driving environment of the vehicle and generating an indication of the surrounding environment; determining, among trained visual prompts received via a network from a server, a target visual prompt corresponding to the pieces of data; generating a merged image by combining a driving image of the autonomous vehicle with the target visual prompt using a predetermined operation; and performing object detection by inputting the merged image into a neural network model of the vehicle, the neural network model configured to infer objects from images inputted thereto.

Abstract: A method of generating lane information using a neural network includes generating a lane probability map based on an input image, generating lane feature information and depth feature information by applying the lane probability map to a second neural network, generating depth distribution information by applying the depth feature information to a third neural network, generating spatial information based on the lane feature information and the depth distribution information, generating offset information including a displacement between a position of a lane and a reference line by applying the spatial information to a fourth neural network, and generating three-dimensional (3D) lane information using the offset information.

Abstract: A processor-implemented method including embedding sensing information, from a plurality of sensors, at a current time point with a previous path of a vehicle at a previous time point and topology information for a topology including plural nodes at the previous time point, determining, by inputting the embedded sensing information to a topology-based neural network, a first distribution area and a second distribution area within a search area, where the first distribution area includes a determined feasible path and the second distribution area includes disconnected nodes that are determined to be reconnected or rewired due to an obstacle, and generating a current path at the current time point from a target location of the vehicle to a current position of the vehicle using topology information at the current time point determined based on the determining.
