Embodiment 1

[0035] As Shan mentioned, whether the information perceived by the perception module is accurate or not has an important impact on the safety of autonomous driving equipment such as autonomous vehicles. In practical applications, in order to improve the accuracy of the information perceived by the perception module, it is necessary to use training samples to pre-train the perception module. These training samples are obtained by manually labeling images in image sequences such as videos. In the manual labeling process, the labeler needs to label the obstacles, vehicles, pedestrians, traffic signs and other labeling objects contained in each image in the image sequence, and then use the labeled images as training samples.

[0036] However, this method of obtaining training samples through manual labeling is usually inefficient, and is not applicable in scenarios where efficient training samples need to be obtained. For example, when the number of training samples required for p...

Embodiment 2

[0109] Based on the same inventive concept as that of Embodiment 1, Embodiment 2 of the present application provides an image tagging device, which can be used to solve problems in the prior art. Such as Figure 6 As shown, the device 60 includes: an image block determination unit 601, a feature information determination unit 602, and a labeling unit 603, wherein:

[0110] An image block determining unit 601, configured to determine at least one image block in the image to be marked;

[0111] A feature information determining unit 602, configured to respectively determine feature information of each of the image blocks, where the feature information is used to uniquely represent the corresponding image block;

[0112] A labeling unit 603, configured to label the image block corresponding to the target feature information when there is target feature information matching the reference feature information in each feature information, so as to realize the Annotation of an annot...

Abstract

The invention discloses an image labeling device, which comprises an image block determining unit, a feature information determining unit and a labeling unit, wherein the image block determining unitis used for determining at least one image block in an image to be labeled; the feature information determining unit is used for independently determining the feature information of each image block,wherein the feature information is used for uniquely expressing the corresponding image block; and the labeling unit is used for labeling the image block corresponding to target feature information soas to label a labeling object in the image to be labeled when the target feature information matched with datum feature information is in the presence in each piece of feature information, wherein the datum feature information corresponds to the labeling object. By use of the image labeling way, the image block is automatically labeled so as to overcome the problem of low manual labeling efficiency in the prior art, and a foundation is laid for effectively obtaining a training sample.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to an image tagging device. Background technique [0002] With the continuous development of science and technology, self-driving equipment such as self-driving cars has attracted more and more people's attention. Usually, the automatic driving of automatic driving equipment needs the help of an automatic driving system. Generally speaking, the automatic driving system will include a perception module, which can perceive the information of obstacles, vehicles, pedestrians, traffic signs, etc. around the automatic driving equipment. The automatic driving system can determine a safe driving path based on the information perceived by the sensing module, so that the automatic driving device can drive along the path. Therefore, whether the information perceived by the sensing module is accurate or not depends on the safety has a significant impact. [0003] In pr...
