摘要： The disclosure provides an image-based vehicle damage assessment method, an image-based vehicle damage assessment apparatus and an image-based vehicle damage assessment system, and relates to the field of artificial intelligence, in particular to computer vision and deep learning technologies, and can be used in smart cloud and vehicle damage assessment scenarios. The method includes: obtaining an image to be assessed of a damaged vehicle; outputting a first damage assessment box and first damage information based on the image to be assessed; in response to a first box selection operation on the image to be assessed, determining and outputting a second damage assessment box and second damage information corresponding to the first box selection operation, wherein a vehicle damage image indicated by the second damage assessment box is different from the vehicle damage image indicated by the first damage assessment box, and the second damage information is vehicle damage information of the vehicle damage image indicated by the second damage assessment box. Therefore, the flexibility and diversity of vehicle damage assessment can be realized, the omission of damaged parts of the vehicle can be avoided, so that the technical effect of comprehensiveness and reliability for vehicle damage assessment can be improved.
