Oriented Object Detection
Detect objects with rotational awareness in aerial imagery
Quick Start
import { geoai } from "@geobase-js/geoai";
// Initialize pipeline
const pipeline = await geoai.pipeline(
[{ task: "oriented-object-detection" }],
providerParams
);
// Run detection
const result = await pipeline.inference({
inputs: { polygon: myPolygon },
postProcessingParams: {
conf_thres: 0.5,
iou_thres: 0.45,
},
});
console.log(`Found ${result.detections.features.length} oriented objects`);🔄
Detects objects with their actual orientation using rotated bounding boxes instead of standard rectangles
Parameters
Post-Processing
postProcessingParams: {
conf_thres: 0.5, // Confidence threshold (0.0-1.0)
iou_thres: 0.45, // Non-Maximum Suppression threshold
multi_label: true // Allow multiple labels per detection
}Map Source
mapSourceParams: {
zoomLevel: 22;
