Title
(EN) COMPUTER-EXECUTED METHOD AND APPARATUS FOR ASSESSING VEHICLE DAMAGE
(FR) PROCÉDÉ EXÉCUTÉ PAR ORDINATEUR ET APPAREIL D'ÉVALUATION D'ENDOMMAGEMENT DE VÉHICULE
Abstract
(EN)
Embodiments of the present specification provide a computer-executed method and apparatus for assessing vehicle damage. According to this method, in a smart damage assessment process, damage and components in a vehicle damage image are first identified using a damage detection model and a component model, respectively, and then the damage and component identification results are geometrically combined according to positions to produce candidate items (component categories, damage categories), and corresponding features are further combined to produce a component-level damage feature for each of the candidate items. Then, the candidate items of a single image or a plurality of images are judged using a prediction model, and finally a smart decision for the entire case is output.
(FR)
Selon certains modes de réalisation, la présente invention concerne un procédé exécuté par ordinateur et un appareil d'évaluation d'endommagement de véhicule. Selon le présent procédé, lors d'un processus d'évaluation d'endommagement intelligent, un endommagement et des composants d'une image d'endommagement de véhicule sont d'abord respectivement identifiés à l'aide d'un modèle de détection d'endommagement et d'un modèle de composant, puis les résultats d'endommagement et d'identification de composant sont géométriquement combinés conformément à des positions pour produire des éléments candidats (catégories de composant, catégories d'endommagement), et des caractéristiques correspondantes sont en outre combinées pour produire une caractéristique d'endommagement de niveau de composant pour chaque élément des éléments candidats. Ensuite, les éléments candidats d'une seule image ou d'une pluralité d'images sont estimés à l'aide d'un modèle de prédiction, et enfin une décision intelligente du cas complet est délivrée.
