Embodiment Construction

[0086] All the features disclosed in this specification, or all disclosed methods or steps in the process, except for mutually exclusive features and / or steps, can be combined in any manner.

[0087] Any feature disclosed in this specification, unless specifically stated, can be replaced by other equivalent or equivalent alternative features. That is, unless otherwise stated, each feature is just one example of a series of equivalent or similar features.

[0088] Deep learning is a machine learning theory that combines low-level features to form more abstract high-level representation attribute categories or features to discover distributed feature representations of data. It can be divided into supervised learning and unsupervised learning. Convolutional neural network is a deep learning model under supervised learning. It is a non-fully connected neural network structure that can automatically learn target features containing a large amount of data. , It has certain robustness t...

Abstract

The invention relates to the field of image detection, and especially relates to an automobile surface damage classification method and device based on deep learning. According to the method and the device, the classification method and device are provided for the problems in the prior art. Characteristic learning and classification are carried out on input to-be-detected images. Specifically, candidate areas are extracted from the to-be-detected images to by employing an area selective search algorithm, and location information of the candidate areas are recorded; the to-be-detected images are input into a characteristic diagram extraction network model without an output layer, thereby extracting the characteristic vectors of the candidate areas of the to-be-detected images; the characteristic vectors of the candidate areas are input into an SVM classifier to find target characteristic vectors; the locations of the corresponding candidate areas on the to-be-detected images, namely, the target areas of the to-be-detected images, are found according to the locations of the target characteristic vectors in the characteristic diagram; and the target areas of the to-be-detected images are input into an optimum classification network model, and the probabilities of the areas on damage levels are output.

Description

Technical field [0001] The invention relates to the field of image detection, in particular to a method and device for classification of car surface damage based on deep learning. Background technique [0002] In recent years, with the continuous development of my country's urbanization, the number of vehicles per capita in my country has continued to increase. The survey shows that as of 2015, the total number of cars in the country has exceeded 170 million. At the same time, the safety problems caused by cars are also increasing. After an accident, no matter whether it is a collision between motor vehicles or between a vehicle and a fixed object, it will leave marks on the vehicle. These traces will seriously affect the appearance and use of the car, and different types of traces require different maintenance costs. Therefore, these traces need to be evaluated. At present, the assessment of scratches on the appearance of automobiles mainly relies on the subjective judgment of...
