Abstract
Methods, storage media, and systems for generating a three-dimensional line segment are disclosed. Exemplary implementations may: receive a plurality of images; generate a point cloud based on the plurality of images; detect a two-dimensional line segment in a first image; project a set of 3d points of the plurality of 3d points as 2d points in the first image; select projected 3d points that are proximate to 2d points along the 2d line segment; and generate a 3d line segment by connecting 3d points of the point cloud represented by the selected projected 3d points.
Claims21
A method for generating a three-dimensional (3d) line segment, the method comprising:
- receiving a plurality of images;
- generating a point cloud based on the plurality of images, wherein the point cloud comprises a plurality of 3d points;
- detecting a two-dimensional (2d) line segment in a first image;
- projecting a set of 3d points of the plurality of 3d points as 2d points in the first image;
- selecting projected 3d points that are geometrically proximate to 2d points of the 2d line segment;
- generating a 3d line segment by connecting the selected projected 3d points of the point cloud.
