I’m looking to capture images for detection of signs, streetlights, drains, and pavement markings. Is there a required density of images before mapillary will place a point on the map? Are images needed in both directions to capture a location of an asset that is non directional (can be seen in both directions) like a streetlight?  
Reason I’m asking is that I uploaded some sample photos and they have objects detected in them, but the map hasn’t been updated yet.
