Abstract: A method for detecting and labeling a target object in a 2D image includes receiving a plurality of 2D images from a visual sensor, manually marking points of the target object on each of the 2D images, generating from the 2D images a 3D world coordinate system of the environment surrounding the target object, mapping each of the marked points on the 2D images to the 3D world coordinate system using a simultaneous localization and mapping (SLAM) engine, automatically generating a 3D bounding box covering all the marked points mapped to the 3D world coordinate system, mapping the 3D bounding box to each of the 2D images, generating a label for the target object on each of the 2D images using a machine learning object detection model, and training the machine learning object detection model based on the generated label for the target object.

Abstract: Dispatching messages in a moving object, in one aspect, may include receiving a description of a spatial area. A hierarchical tree representation of the spatial area may be generated. The hierarchical tree representation may comprise nodes, wherein a child node represents a sub-region of a region represented by a parent node of the child node. Moving features may be associated with each of the nodes, the moving features comprising whether the node is cacheable, whether the node covers an unpartitioned area, an active object list in an area covered by the node, and a latest position associated with an object in the active object list. Data from the moving object may be dispatched based on the hierarchical tree representation.

Abstract: Embodiments of the present invention provide information processing systems and methods for proliferating testing data based on sample testing data. In one embodiment, a difference is determined by comparing a desired query result to a query result acquired by executing a query statement on sample testing data. Sample testing data can then be proliferated based, at least in part, on the difference and data generation constraint conditions.
