About this package

The goal of APB_spatial_computer_vision is to provide a framework to perform computer vision tasks on geospatial imagery. Its focus is semantic segmentation, mainly though SAM. The logic can be accessed in several points:

• Through text, to perform image to bbox tasks via Grounding DINO.
• Through bounding box, to perform SAM and achieve segmentation.
• Throgh a lower resolution vector dataset coming from another model, in an attempt to improve segmentation.

Tools

• 🦆 The program leverages Spatial-SQL DuckDB queries for precise vector operations
• ⚡ Image pyramids have been optimized via concurrency to GDAL-warping
• 📷 Integration of virtual layers through GDAL to SAMGeo
• 📄 MKDocs for automated docs+ jupyter visualization

Instructions

The entry points of the system are the following environment variables:

• TEXT_PROMPT: a string with the prompt to look for via Grounding DINO
• VECTOR_DATASET: a vector dataset
• DATA_DIR: location of the data
• BASE_DIR: where this package is located, acessible for deployments
• NAME_ORTOFOTO: basename for the image to be processed
