I just uploaded a series of images (Gold Coast, Australia) using the command line tool. I’ve turned on Data Point settings, and I can see the speed signs have been detected in the images, however, I couldn’t see it on the map nor download it. I’m wondering what I did wrong. Thanks
Data point (speed sign) detected in image not show up on map
Thanks for your message @sealjack. @chrisbeddow, do you know what can be the reason?
@sealjack this was a temporary error while we were switching over a tile service system. It should be okay today, can you do a shift + refresh on the page and confirm?
Thanks @Yaro @chrisbeddow , tried Shift + refresh in Incogonito mode. Unfortunately, I still can’t see the speed signs or other detected signs on the map.
Okay, let’s see what we can do to regenerate the area perhaps. Because it is not just 1 traffic sign, but the whole area, there must be some problem like the data failed to generate.
not the whole area as I can see extracted signs in the suburbs nearby. I’m wondering if it has something to do with the camera. The images I have here were converted using the Mapillary commandline tool from a geotagged video captured by a basic Navman dashcam, so resolution is not that great, and images might not have enough like aperture, focal length etc. in order to determine the relative distance. attached is one of the converted images.
It should be very visible still to the computer vision algorithm, it does not need necessarily amazing image quality.
What I mean by the whole area is probably a “map tile” , roughly something like a 300x300 meter square. We produce the data in batches of that size and one could have been missed.
Plenty of these signs, and other non-traffic sign objects, should be very visible here.
However, can you share the commands you are giving when processing and uploading the imagery? It might be nice to make sure you have a smaller time or distance interval between images, about double the density, which could produce better quality. Overlap between photos, and not just what’s visible in a single photo, is helpful.
hi Chris, here’s the command I ran for processing the video to images
mapillary_tools video_process C:\Users\jack\Downloads\FILE230322-060451.mp4 --geotag_source "gpx" --geotag_source_path C:\Users\jack\Downloads\FILE230322-060451.gpx --interpolation_use_gpx_start_time --video_sample_distance -1 --video_sample_interval 2
