Scale-Invariant Line Descriptors for Wide Baseline Matching

Nettet17. sep. 2016 · Most of existing line matching methods use texture information near lines as descriptors. Wang et al. proposed a SIFT-like descriptor, the mean-standard deviation line descriptor (MSLD). In many images, the textures in the vicinity of line segments are not rich enough to assemble an effective descriptor. Nettet7. jan. 2013 · The straightforward approach would be to compare each 2D segment to each 3D segment, best match is the one that most closely corresponds to the predicted length and position when compared to the actual.

Nettet1. feb. 2024 · Line segment matching is important in applications that require recovering the 3D structure of objects (e.g., manmade objects in street-level scenarios). However, differentiating between true and false line matches is generally difficult without strong geometric constraints for line segments. Nettet1. apr. 2008 · This paper describes an efficient localization algorithm based on a vector-matching technique for mobile robots with laser range finders. As a reference the method uses a map with line-segment vectors, which can be built from a CAD layout of the indoor environment. The contribution of this work lies in the overall localization process.
