Abstract

The invention discloses an image annotation method and device used in three-dimensional simulation and electronic equipment, and the method comprises the steps: constructing a three-dimensional scene which comprises a target object, a virtual camera and a shielding object; acquiring an image in a visual field range through the virtual camera; judging whether the target object is in the field of view of the virtual camera, and if the target object is in the field of view of the virtual camera, generating a detection point of the target object; and if any one of the detection points is not shielded by the shielding object, marking a target object in the image.

Description

technical field [0001] The present application relates to the field of data labeling, in particular to an image labeling method and device, and electronic equipment used in 3D simulation. Background technique [0002] Image annotation, in simple terms, is to mark the type, location, speed and other attributes of the target object on the image as the training data for the depth model or other classifiers. To train an excellent algorithm, it is very important to have more data and obtain more accurate labeling information. [0003] The current training data mainly comes from the on-site collection of physical sensors. Data collection is costly and difficult, and the later labeling is mainly manual. The advantage is that the environment for collecting training data is highly consistent with the working environment of the final model, which has a great impact on the recognition accuracy of the model. big help. Recently, 3D simulation technology has also been used to generate t...
