Method and device for labeling targets

Abstract

The invention discloses a method and device for labeling targets, and belongs to the technical field of picture processing. The labeling result of the targets can be used for training a target detector. The method comprises obtaining training data, using a classifier for carrying out target detection on the training data to obtain a first target position collection, calculating the precision of the classifier, selecting the targets not meeting assigned confidence coefficient requirements from the first target position collection and output the targets to carry out false drop labeling when the precision of the classifier does not meet an assigned precision requirement, obtaining a second target position collection, combining the targets meeting the assigned confidence coefficient requirements in the first target position collection and the second target position collection to form a target labeling collection, carrying out training on the classifier according to the target labeling collection, and executing the mentioned steps repeatedly until the precision of the classifier meets the assigned precision requirement. The device comprises a target detection module, a performance testing module, a learning module, a training module and an iteration module. The method and device for labeling the targets greatly reduces the cost of manually labeling, and improves efficiency of target labeling.
