Article damage detection
First Claim
1. A method for evaluating damages to an article, comprising:
- obtaining at least two images that are time sequentially related and show the article at different angles;
providing the at least two images as input to a detection model in time order, wherein the detection model comprises a deep convolutional neural network and a long short-term memory (LSTM) network that have been jointly trained on a set of training samples, each training sample comprising multiple training images associated with labels indicating respective article damage degrees of an article shown in the multiple training images;
processing the at least two images using the deep convolutional neural network to output a feature processing result for each image based on respective features identified from the image;
processing the feature processing result using the long short-term memory (LSTM) network to receive the feature processing results and to output a damage detection result based on performing time series analysis on the feature processing results, wherein the damage detection result comprises a classification result of each of one or more types of damage; and
obtaining, as output from the detection model, the damage detection result.

Abstract
The present specification provides an article damage detection method, including: obtaining at least two images that are time sequentially related and show a detected article at different angles; and inputting the images to a detection model in time order, to determine a damage detection result, where the detection model includes a first sub-model and a second sub-model, the first sub-model identifies respective features of each image, a feature processing result of each image is input to the second sub-model, the second sub-model performs time series analysis on the feature processing result to determine the damage detection result, and the first sub-model and the second sub-model are obtained by performing joint training by using training samples labeled with article damage.
