Abstract

The invention discloses a training set acquisition method and related equipment, and relates to a map technology in the technical field of computers. According to the specific implementation scheme, a first training set is obtained, and the first training set comprises artificially marked satellite image samples; image style migration processing is carried out on the satellite image samples in the first training set, a second training set is generated, and the second training set comprises satellite image samples obtained after image style migration processing is carried out on the satellite image samples in the first training set; based on the first training set and the second training set, a target training set is generated, and the target training set comprises a part of or all satellite image samples of the first training set and a part of or all satellite image samples of the second training set. Therefore, the problem of low training set generation efficiency in the failure area mining technology based on the satellite map at present can be solved, and the training set generation efficiency is further improved.

Description

technical field [0001] The present application relates to map technology in the field of computer technology, and in particular to a training set acquisition method, device and electronic equipment. Background technique [0002] In the failure area mining technology based on satellite images, in the case of large-scale terrain changes (such as regional demolition, etc.) in the real world, images collected by satellites are used to identify and classify images using neural network models constructed by deep learning. , find the changed area in the city, circle the "invalid area" in the map corresponding to this area, and process the POI points contained in the circled area offline. [0003] Among them, the neural network model usually needs to be trained through a training set containing a large amount of training data, and the current training set is usually generated by manually collecting data. For example, in the case of regional demolition, a part of the The satellite i...
