Embodiment Construction

[0045] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0046] refer to figure 1 , shows a flowchart of steps of a labeling method provided by an embodiment of the present invention, and the method may specifically include the following steps:

[0047] Step 101, acquiring annotation information for the vehicle image; the annotation information includes first orientation attribute information and second orientation attribute information respectively annotated for at least two side edges of the vehicle; the first orientation attribute information represents the side The edge is located at the front end or the rear end of the vehicle; the second orientation attribute information indicates the relative position of the side edge in the vehicle image.

Abstract

The embodiment of the invention provides a labeling method and device. The method comprises the steps: acquiring the labeling information for a vehicle image, wherein the annotation information comprises first orientation attribute information and second orientation attribute information which are respectively annotated for at least two side edges of the vehicle, the first orientation attribute information indicates that the side edges are located at the front end or the rear end of the vehicle, and the second orientation attribute information represents the relative position of the side edge in the vehicle image; according to the first orientation attribute information and the second orientation attribute information respectively marked for the at least two side edges, determining orientation types respectively corresponding to the at least two side edges. Compared with the mode that labeling personnel directly label the orientation types of the side edges, the labeling personnel only need to label the positions, located at the front end or the rear end of the vehicle, of the side edges and label the relative positions of the side edges in the vehicle image, human cognition is better met, the labeling process can be simpler, and generated labeling data are more accurate.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a labeling method and a labeling device. Background technique [0002] Through the prediction of the side edge of the vehicle, the yaw angle of the vehicle can be estimated more accurately in the pictures taken by the monocular camera, so the prediction result of the yaw angle is very important for the perception system of automatic driving. [0003] In order to be able to train a vehicle side edge prediction model with superior performance, a large number of high-precision manually labeled pictures are essential. Existing labeling methods are exhaustively asking the labeler to label the position of the side edge and select the correct position from the four orientation types. This labeling method is time-consuming and has a high error rate. Contents of the invention [0004] In view of the above problems, embodiments of the present invention are proposed to provide a label...
