Evidencepartial
we rely on a correspondence-free, scan-to-implicit matching paradigm to estimate optimal pose
Implicationpartial
Directly and explicitly stated in the abstract as a core method component for pose estimation.

The entire training process is conducted in a self-supervised manner
Implicationpartial
Directly and explicitly stated in the abstract.
Verificationpartial

Evidencepartial
Extensive experiments on multiple real-world and synthetic datasets demonstrate the superior performance, in terms of the effectiveness and generalization capabilities, of our Hi-LOAM compared to existing state-of-the-art methods.
Implicationpartial
Directly stated in the abstract as a conclusion from extensive experiments, though specific metrics are not provided in the given text.
Verificationpartial
partial
Evidencepartial
which waives the model pre-training and manifests its generalizability
Implicationpartial
Strongly implied in the abstract; the self-supervised manner is stated to 'waive the model pre-training'.
Verificationpartial
partial
Evidencepartial
Most existing LOAM frameworks are either contingent on the supervision signal, or lack of the reconstruction fidelity, which are deficient in depicting details of large-scale complex scenes.
Implicationpartial
Directly stated as a limitation of existing methods that motivates the work, though it is a broad claim about the field.
Verificationpartial
partial
Evidencepartial
these multi-scale latent features are decoded into signed distance value through shallow Multilayer Perceptrons (MLPs) in the mapping procedure
Implicationpartial
Directly and explicitly stated in the abstract as a core method component.
