NettetSparsifying the line cloud is one mitigation to this prob-lem [8,53] but comes with signiﬁcant performance trade-offs in terms of recall and accuracy of the localization re-sults. Second, after successful server-side localization in privacy preserving line cloud maps, the client reveals their precise camera location in the scene. Nettet8. mar. 2024 · To address the resulting potential privacy risks for user-generated content, it was recently proposed to lift point clouds to line clouds by replacing 3D points by randomly oriented 3D lines passing through these points. The resulting representation is unintelligible to humans and effectively prevents point cloud-to-image translation.
