Usage
import panosam as ps
from panosam.engines.sam3 import SAM3Engine
engine = SAM3Engine()
client = ps.PanoSAM(engine=engine, views=ps.PerspectivePreset.DEFAULT)
result = client.segment("panorama.jpg", prompt="car")
for mask in result.masks:
print(f"{mask.label}: yaw={mask.center_yaw:.1f}, pitch={mask.center_pitch:.1f}")
result.save_json("results.panosam.json")
Custom Engine
Any class with a matching segment() method works:
class MyEngine:
def segment(
self,
image: Image.Image,
text_prompt: str,
threshold: float = 0.5,
mask_threshold: float = 0.5,
simplify_tolerance: float = 0.005,
) -> list[ps.FlatMaskResult]:
...
client = ps.PanoSAM(engine=MyEngine())
