Does mapillary provide specific location (lat,lon) of individual detections within an image?

Imagery, data, and integrations
1

I have tried this code at my end, but I end up getting the frame level lat, lon locations.

def get_detections(image_id, access_token):
url = f"https://graph.mapillary.com/{image_id}/detections"
params = {
“access_token”: access_token,
“fields”: “image,value,geometry”
}

try:
    response = requests.get(url, params=params)

    if response.status_code == 200:
        detections_data = response.json()
        # Process the detections_data as needed
        return detections_data
    else:
        print(f"Request failed with status code {response.status_code}")
        return None
except Exception as e:
    print(f"An error occurred: {e}")
    return None

output is :

Please help!

[[[959, 3585], [1189, 3585], [1189, 3195], [959, 3195], [959, 3585]]]

This only gives the detection/segmentation bbox/polygons, not the specific latitude and longitude of individual detections.

If you have tried this in past please direct me to the API or code.
Thank you.
