How privacy preserving are line clouds
Nettet13. mar. 2024 · This paper proposes the first solution to what we call privacy preserving image-based localization. The key idea of our approach is to lift the map representation from a 3D point cloud to a 3D line cloud. This novel representation obfuscates the underlying scene geometry while providing sufficient geometric constraints to enable … Nettet9. mar. 2024 · Finally, we acknowledge recent work has attacked line clouds to reconstruct point clouds [25] but note that this is equivalent to our No-Privacy baseline …

Line 14 requires mn ST circuit on l-bit, which leads to mnl non-XOR gates. Line 16 costs mn non-free gate. Line 21 requires executing the MUX circuit of ml-bit n times, which leads to mnl non-XOR gates. NettetTo 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 …
Nettet20. jul. 2024 · These methods offer a scene privacy protection against the inversion attacks by converting a point cloud to a line cloud, which reconstruct the scene images from the point cloud. However, they are not directly applicable to a video sequence because they do not address computational efficiency. Nettetemphasizes the inherent privacy risks associated with the persistent storage and sharing of 3D point clouds models. Speciale et al. [60] proposed the first solution to address this problem by developing a privacy preserving camera pose estimation technique. They propose to transform 3D point clouds to 3D line clouds in a way that obfuscates the
Nettet20. jul. 2024 · This study proposes a privacy-preserving Visual SLAM framework for estimating camera poses and performing bundle adjustment with mixed line and point clouds in real time. Previous studies have proposed localization methods to estimate a camera pose using a line-cloud map for a single image or a reconstructed point cloud.
