GLMV-Grounding Skill

Extract and visualize grounding results produced by GLM-V. Depending on the user prompt, grounding coordinates in model outputs may appear in different forms, including 2D bounding boxes, Objects Detection JSON, 2D points, 3D bounding boxes, and target-tracking JSON.

Note: GLM-V outputs coordinates where x and y are relative coordinates normalized from pixel coordinates x_pixel and y_pixel using image width W and height H (range 0-1000), i.e., x=round(x_pixel/W1000), y=round(y_pixel/H1000). The origin of the pixel coordinate system is the top-left corner. Note: If the prompt does not explicitly specify a grounding format (for example, "find the location of xxx" or "draw a box around xxx"), treat the request as 2D bounding boxes by default.

When to use

• Use GLM-V to ground targets in images: obtain grounding results in an image for any prompt-described target, with output formats such as 2D bounding box (default), 2D points, and 3D bounding box.
• Use GLM-V to track targets in videos: obtain tracking results in a video for any prompt-described target, with output format like {"0": [{"label": ..., "bbox_2d": ...}, ...], ...}.
• Use utility functions for extraction, conversion, and visualization: extract coordinates, points, and JSON from natural text; normalize and de-normalize coordinates; visualize boxes, points, 3D boxes, and video tracking results.
