TBG SAM3 Depth Map:
The TBGSAM3DepthMap node is designed to generate depth maps from images, providing a visual representation of the distance of objects within a scene. This node leverages advanced depth estimation techniques to create detailed depth maps, which can be used in various applications such as 3D modeling, augmented reality, and image enhancement. By utilizing the MiDaS model, the node can accurately estimate depth information, offering a powerful tool for AI artists to enhance their creative projects. The node can operate in two modes: processing the entire image or focusing on specific segments, allowing for flexibility in how depth information is extracted and applied. This capability is particularly beneficial for artists looking to add depth and dimension to their work, enabling more realistic and immersive visual experiences.
TBG SAM3 Depth Map Input Parameters:
image
The image parameter is the primary input for the node, representing the image from which the depth map will be generated. This parameter is crucial as it serves as the basis for depth estimation, and the quality and content of the image can significantly impact the resulting depth map. The image should be provided in a compatible format, typically as a tensor or a PIL image, to ensure accurate processing.
mode
The mode parameter determines the operational mode of the node, with options including "full_image" and "per_segment". In "full_image" mode, the node processes the entire image to generate a comprehensive depth map. In "per_segment" mode, the node focuses on specific segments of the image, requiring additional segment input to function. The default mode is "full_image", and the choice of mode affects how depth information is extracted and applied, offering flexibility based on the user's needs.
normalize
The normalize parameter is a boolean option that, when enabled, normalizes the depth map values to a range between 0 and 1. This normalization process ensures that the depth values are scaled consistently, which can be beneficial for visualization and further processing. The default value is True, meaning normalization is applied by default, providing a standardized output that is easier to interpret and use in subsequent applications.
segs
The segs parameter is an optional input that provides segment information when the node is operating in "per_segment" mode. This parameter allows the node to focus on specific areas of the image, generating depth maps for individual segments rather than the entire image. The segments should be provided in a compatible format, and this parameter is essential for users who wish to apply depth estimation to specific parts of an image.
TBG SAM3 Depth Map Output Parameters:
depth_image
The depth_image output is a visual representation of the depth map, formatted as an image with dimensions [H, W, C]. This output provides a detailed view of the depth information extracted from the input image, allowing users to visualize the relative distances of objects within the scene. The depth image is particularly useful for artists looking to incorporate depth cues into their work, enhancing the realism and dimensionality of their creations.
depth_mask
The depth_mask output is a simplified representation of the depth map, formatted as a mask with dimensions [H, W]. This output provides a more abstract view of the depth information, which can be used for various applications such as masking, segmentation, and further processing. The depth mask is valuable for users who need a concise representation of depth information for integration into other workflows or tools.
TBG SAM3 Depth Map Usage Tips:
- To achieve the best results, ensure that the input image is of high quality and contains clear details, as this will improve the accuracy of the depth estimation.
- When using the "per_segment" mode, provide well-defined segments to focus the depth estimation on specific areas of interest, which can be particularly useful for complex scenes with multiple objects.
TBG SAM3 Depth Map Common Errors and Solutions:
Could not load depth model
- Explanation: This error occurs when the MiDaS depth model fails to load, possibly due to missing dependencies or network issues.
- Solution: Ensure that all required libraries, such as
transformers, are installed and that there is a stable internet connection to download the model. If the problem persists, check for any compatibility issues with the current environment.
Model not loaded, returning dummy depth
- Explanation: This message indicates that the depth model was not successfully loaded, and a dummy depth map is being returned as a fallback.
- Solution: Verify that the model loading process is completed without errors. Check the console for any error messages during the model loading phase and address any issues related to missing files or incorrect configurations.
