Embodiment 1

[0043] figure 1 It shows a flow chart of a vehicle damage assessment method provided by an embodiment of the present invention, refer to figure 1 , the above methods include:

[0044] Step S110: Obtain the identity information of the damaged vehicle, and establish a point cloud model of the damaged vehicle;

[0045] Specifically, in the embodiment of the present invention, a point cloud scanning device or a mobile terminal with a point cloud scanning function is preferred to scan the damaged vehicle, and then form a three-dimensional modeling of the damaged vehicle, which is a three-dimensional point cloud model.

[0046] What needs to be added is that during the process of scanning the damaged vehicle, the owner of the point cloud scanning device also needs to obtain other identity information of the damaged vehicle, such as the identification code (vin code) of the vehicle identity, and then can according to The above identity information is used to determine the basic inf...

Embodiment 2

[0064] On the basis of Embodiment 1, this embodiment of the present invention provides another vehicle damage assessment method. The difference from Embodiment 1 is that after obtaining the identity information of the damaged vehicle and establishing the point cloud model of the damaged vehicle, it also includes : Measure the length of the damaged part in the point cloud model; measure the area of ​​the damaged part in the point cloud model. This is because if the vehicle only has surface damage, the damage can be determined only by calculating the damaged length / area instead of deformation analysis or damage analysis.

[0065] Specifically, measure the length of the damaged part in the point cloud model, including:

[0066] Obtain the three-dimensional coordinates of the endpoint of the damaged part;

[0067] According to the three-dimensional coordinates, the length of the damaged part is calculated.

[0068] It should be noted that in the point cloud model, each point clo...

Embodiment 3

[0075] image 3 It shows a flow chart of damage analysis in a vehicle damage determination method provided by an embodiment of the present invention; image 3 As shown, the method includes:

[0076] Step S210: Set a deformation threshold, and pick a point cloud in the point cloud model whose deformation value is greater than the deformation threshold. Specifically, the vehicle damage assessment platform sets a deformation threshold, the purpose of which is to divide the deformation degree of the vehicle damage assessment, filter the part of the point cloud whose deformation value is less than the deformation threshold, and obtain the point cloud whose deformation value is greater than the deformation threshold.

[0077] Step S220: clustering and analyzing the point cloud, and dividing the point cloud into a plurality of point cloud subsets. Through cluster analysis (such as Euclidean distance k-means clustering), the vehicle damage assessment platform can cluster and divide ...

Abstract

The invention provides a vehicle damage assessment method and system, and relates to the technical field of vehicle damage assessment. The method comprises the steps of obtaining identity informationof a damaged vehicle, and building a point cloud model of the damaged vehicle; according to the identity information of the damaged vehicle, searching for a vehicle model library to obtain model information matched with the identity information; according to the point cloud model and the model information, performing calculation to obtain a deformation value of each point cloud in the point cloudmodel; and according to the deformation value of each point cloud in the point cloud model, obtaining vehicle damage depth information and area information through damage analysis. The technical problem of incapability of obtaining depth information of a damaged part due to low accuracy caused by performing vehicle damage assessment through obtaining a remote image of a vehicle accident site at present is solved; and the technical effect of performing accurate damage assessment on the damaged vehicle is achieved.

Description

technical field [0001] The invention relates to the technical field of vehicle loss assessment, in particular to a vehicle loss assessment method and system. Background technique [0002] With the continuous development of social economy, the vehicle ownership rate is also getting higher and higher. Correspondingly, the phenomenon of vehicle damage is becoming more and more frequent, so fast vehicle damage assessment is particularly important for people's work and life. [0003] The traditional vehicle damage assessment is based on the principle of vehicle structure, comprehensively analyzes the vehicle and the accident scene through scientific and systematic professional inspection, testing and survey methods, and uses vehicle damage assessment data and maintenance data to estimate and price the vehicle collision repair. Generally, insurance companies use manual damage assessment to assess vehicle damage. With the continuous development of communication technology, auto i...
