Abstract: The disclosure relates to technology for object detection in which a vision system receives training datasets including a set of two-dimensional (2D) images of the object from multiple views. A set of 3D models is reconstructed from the set of 2D images based on salient points of the object selected during reconstruction to generate one or more salient 3D models of the object that is an aggregation of the salient points of the object in the set of 3D models. A set of training 2D-3D correspondence data are generated between the set of 2D images in a first training dataset of the training datasets and the salient 3D model of the object generated using the first training dataset. A deep neural network is trained using the set of training 2D-3D correspondence data generated using the first training dataset for object detection and segmentation.

Abstract: The present invention provides a method and an apparatus for transmitting a broadcast signal. The method includes: performing dividing processing on an antenna array in a multi-antenna system to obtain multiple subarrays; obtaining a basic weight vector of each subarray among the multiple subarrays, where the basic weight vector makes a beam peak-to-average power ratio of each subarray lower than a preset threshold and makes beam patterns of different subarrays complementary to each other in a direction dimension; performing, according to a weight coefficient in each basic weight vector, weighted processing on a transmit signal of an array element in a subarray corresponding to the each basic weight vector to obtain a first signal and use the array element to transmit the first signal. The present invention implements full coverage of the broadcast signal from the multi-antenna system in all directions in a cell or a sector.
