[1/3 - Anomaly Detection] [1/2 - KNN Classification] Batch Upload Dataset to Qdrant (Crops Dataset)
Key Features and Highlights
This workflow implements the entire process of batch importing agricultural crop image datasets into the Qdrant vector database. It covers data preprocessing, batch generation of multimodal image embedding vectors, and efficient uploading. Highlights include automatic detection and creation of Qdrant collections, support for batch UUID generation to ensure data uniqueness, integration with Voyage AI’s multimodal embedding API for image vector conversion, and stable data retrieval from Google Cloud Storage.
Core Problems Addressed
This workflow solves the challenge of batch uploading large-scale image datasets from cloud storage to a vector database, specifically for image collections with structured category labels (e.g., crop names). It ensures standardized data structure, efficient upload, and supports subsequent vector-based similarity search and anomaly detection.
Application Scenarios
- Data preparation for anomaly detection and classification model building in agricultural crop imaging
- Batch data import for any machine learning applications based on image embeddings
- Rapid dataset initialization for the Qdrant vector database
- Application of multimodal embedding technology in image retrieval and classification scenarios
Main Process Steps
- Manually trigger the workflow start
- Configure and verify the existence of the Qdrant cloud collection; if absent, create the collection and establish a payload index based on “crop_name”
- Batch fetch crop image data from Google Cloud Storage (filtering out the “tomato” category for anomaly detection testing)
- Construct publicly accessible URLs for each image and extract crop names as labels
- Group data into batches with configurable batch size, generating corresponding UUIDs as unique identifiers for Qdrant points
- Call Voyage AI’s multimodal embedding API to convert images in batches into 1024-dimensional vectors
- Upload vectors and corresponding metadata to the Qdrant collection in batches for persistent storage
