Problems solved by technology

[0006] This embodiment is used to solve the problem that manual labeling cannot achieve refined labeling and labeling efficiency is low. By performing edge detection on the initial target frame manually marked, the proximity of the edge of the target frame to the actual edge in the image is improved, and the target frame is detected through target detection. The algorithm automatically labels the image, improving the accuracy and speed of labeling

Abstract

The invention provides a data annotation method and device and a data annotation model training method and device. The data annotation method comprises the following steps: acquiring a to-be-annotated image set, and determining the annotation type of a to-be-annotated target of each to-be-annotated image; judging whether the labeling category of the to-be-labeled target of each to-be-labeled image has a corresponding data labeling model or not; if yes, performing target annotation on the to-be-annotated image through the data annotation model to obtain a first annotated data set; and if not, acquiring an initial target frame of a to-be-labeled target in the to-be-labeled image, detecting a target edge position in the initial target frame of the at least one to-be-labeled target, and adjusting the initial target frame of the at least one to-be-labeled target according to the target edge position to obtain a second labeled data set. According to the invention, the image which cannot be automatically annotated is annotated by assisting an image processing technology with manual annotation, and the annotation quality and efficiency are improved in a manner of combining automation with the manual annotation.

Description

technical field [0001] The present application relates to the field of data processing, in particular to a data labeling method and device, and a data labeling model training method and device. Background technique [0002] In recent years, urban governance has become a hot spot. Through the extensive monitoring layout and the in-depth application of information technologies such as artificial intelligence and cloud computing, the urban governance model has completed the transformation from traditional monitoring "seeing" to "understanding". Technology promotes the development of urban intelligent construction and is also the only way for urban governance. [0003] In order for the machine to "understand", the machine first needs to recognize the relevant targets in the video image. In the existing technology, the relevant targets in the image will be manually marked, and then the machine will continue to learn, so as to improve the recognition of the corresponding target. ...
