Depth map control is the conditioning approach that uses per-pixel depth estimates to guide scene geometry and spatial relationships - it improves three-dimensional consistency in generated images.

What Is Depth map control?

• Definition: Depth map encodes relative distance, helping model place objects in plausible perspective.
• Input Sources: Depth can come from monocular estimators, sensors, or rendered scene assets.
• Control Scope: Influences layout, scale relations, and foreground-background separation.
• Task Fit: Useful in environment design, AR content, and cinematic composition workflows.

Why Depth map control Matters

• Spatial Coherence: Reduces flat or inconsistent perspective common in text-only generation.
• Layout Reliability: Improves object placement in complex multi-depth scenes.
• Cross-Modal Utility: Depth control integrates well with text prompts and style references.
• Editing Power: Supports scene-preserving restyling while keeping depth structure fixed.
• Input Risk: Incorrect depth estimates can impose unrealistic geometry.

How It Is Used in Practice

• Depth Quality: Use robust depth estimators and post-process noisy maps.
• Normalization: Apply consistent depth scaling between preprocessing and inference.
• Hybrid Controls: Pair depth with edge or segmentation controls for stronger structure.

Depth map control is a key geometry-conditioning method for diffusion control - depth map control is most reliable when depth estimation quality is validated before generation.
