Abstract
(EN)
Techniques for validating data that represents an environment are discussed herein. In examples, the techniques can associate data of an environment with a voxel space including multiple voxels. The techniques can analyze the voxels to identify an error, such as multiple layers for a single surface in an environment, a hole for a location in an environment where a hole does not exist, uneven regions for a smooth surface in an environment, and so on. In some examples, when an error has been identified, an action can be performed, such as displaying a representation associated with the data and an indication of the error, storing an indication of the error in a log file, updating a trajectory for a vehicle, updating the data or a mesh associated with the data, and so on.

L'invention concerne des techniques de validation de données qui représentent un environnement. Dans des exemples, les techniques peuvent associer des données d'un environnement à un espace de voxels comprenant de multiples voxels. Les techniques peuvent analyser les voxels pour identifier une erreur, telle que de multiples couches pour une seule surface dans un environnement, un trou pour un emplacement dans un environnement dans lequel il n'existe pas de trou, des régions irrégulières pour une surface lisse dans un environnement, et ainsi de suite. Dans certains exemples, lorsqu'une erreur a été identifiée, une action peut être effectuée, telle que l'affichage d'une représentation associée aux données et d'une indication de l'erreur, le stockage d'une indication de l'erreur dans un fichier journal, la mise à jour d'une trajectoire pour un véhicule, la mise à jour des données ou d'un maillage associé aux données, et ainsi de suite.
