Abstract

The invention provides an automobile part damage assessment method and belongs to the field of automobile damage assessment. The automobile part damage assessment method is used for solving a problem that an automobile damage degree cannot be truly reflected by extracted information because feature information extracted via technologies of the prior art is incomplete. Key technical points of the automobile part damage assessment method are that the automobile part damage assessment method comprises a step of information collection, a step of information processing and a step of part damage assessment. When automobile part information is collected, a step of extracting multidimensional features of automobile parts is conducted; the multidimensional features comprise texture information and contour information. The beneficial effects of the automobile part damage assessment method are that the contour information and the texture information can fully reflect deformation of the parts, the multidimensional features are extracted, and damage conditions of the parts can be effectively measured.

Description

technical field [0001] The invention belongs to the field of damage assessment of automobiles, and in particular relates to a damage assessment method for automobile parts. Background technique [0002] The current world is in the era of rapid development of mobile Internet technology. After the vehicle collides, the vehicle itself will produce various deformations and damages. However, only relying on the loss assessment personnel to determine the accident vehicle damage based on experience, there are many subjectivity and joint fraud. Guaranteed chance. In the automotive field, performance is constantly being updated, and automotive systems are becoming more and more complex. Although smart glasses for cars have not appeared or become popular in the market at present, the concepts put forward are quite rich, so that they can meet the various needs of users. For example, the augmented reality glasses launched by BMW are currently attracting attention. Including services:...
