摘要： A method and apparatus for outputting three-dimensional (3D) lines. The apparatus acquires a first image and a second image including lines on a road, generates, based on a first feature map acquired from the first image, a line probability map representing a probability that a pixel point of the first feature map belongs to the lines, calculates matching information of the first image and the second image based on the first feature map and a second feature map acquired from the second image, predicts depth values of the lines using the line probability map and the matching information, detects the lines based on the line probability map, generates 3D lines based on the detected lines and the depth values of the lines, and outputs the 3D lines.

摘要： A processor-implemented method includes obtaining a first motion matrix corresponding to an extended reality (XR) system and a second motion matrix based on a conversion coefficient from an XR system coordinate system into a rolling shutter (RS) camera coordinate system, and projecting an RS color image of a current frame onto a global shutter (GS) color image coordinate system based on the second motion matrix and generating a GS color image of the current frame, wherein the second motion matrix is a motion matrix of a timestamp of a depth image captured by a GS camera corresponding to a timestamp of a first scanline of an RS color image captured by the GS camera.

摘要： An object detection method includes setting a first window region and a second window region larger than the first window region that correspond to partial regions of different sizes in an input image, downsampling the second window region to generate a resized second window region, detecting a first object candidate from the first window region and a second object candidate from the resized second window region, and detecting an object included in the input image based on one or both of the first object candidate and the second object candidate.
