1, rectangular box labeling
Rectangular frame labeling is a simple way to label target objects with target detection frame, which is often used to label people, cars and things under automatic driving.
2. Polygon labeling
Polygon labeling refers to labeling irregular target objects with polygonal frames in static pictures. Compared with rectangular box labeling, polygon labeling can frame the target more accurately and be more targeted for irregular objects.
3. Key point marking
The biggest application of key point labeling template is to label the key points of human face. By marking the key points in different directions, we can judge the function of people in the image.
4.3D point cloud labeling
Three-dimensional point cloud labeling refers to frame selection and labeling using data collected by lidar, which is used to train artificial intelligence models such as computer vision and unmanned driving.
5, three-dimensional cube labeling
Different from point cloud labeling, 3D cube labeling is still based on 2D plane images. The labeling machine frames the edges of three-dimensional objects to obtain vanishing points and measure the relative distance between objects.
