Abstract: There are provided a system and a method for generating data-based autonomous driving test scenarios for testing and evaluation of autonomous driving system. An autonomous driving test scenario generation method according to an embodiment generates tracked objects by using tracked object data that an autonomous driving vehicle collects while traveling, determines some non-tracked objects among the tracked objects and reflects a non-tracking factor on non-tracked object data, and generates an autonomous driving test scenario by using elements within an operational design domain of an autonomous test scenario and the non-tracked object data reflecting the non-tracking factor. Accordingly, scenarios for testing not only determination, control functions but also a recognition function are generated based on data acquired by autonomous driving, so that more inclusive, detailed testing and evaluation can be provided for autonomous driving systems performing dynamic driving tasks.

Abstract: There is provided a deep learning-based motion recognition method and system using multiple feature information. A motion recognition method according to an embodiment reshapes time-series image data obtained by shooting a target object to a type of image data of a spatial domain, extracts spatial features from the reshaped image data, reshapes the image data from which the spatial features are extracted to a type of time-series image data, integrates the time-series image data and time-series key point data of the target object, extracts temporal features from the integrated time-series data, and recognizes motions of the target object based on the extracted temporal features. Accordingly, motions can be more stably recognized even when there are a plurality of objects at the same time and an overlap, occlusion frequently occur, and lots of computations are not required and motion recognition can be performed in a small low-power edge device having relatively low computing power.
