I've been trying to improve the accuracy of the geotagging of images produced using a Canon S100 running CHDK and the KAP lua script, shutter triggered by Pixhawk via a CamRemote device.
I've been getting good results, but the accuracy of the geotagging is limited by the 1 second resolution of the timestamps for the images. Clock on the camera is synced via GPS time.
The KAP script, however, is able to log the shutter release time to ~10ms precison, which should be good enough for quite accurate geotagging.
Can anyone tell me how to incorporate the accurate time information into a geotagging procedure? Editing the exif data on the images doesn't work as the datetimeoriginal value can only be defined down to a second.
The ideal would be to add the geolocation data to the images using the flight logs and the KAP script log, but any reasonably streamlined way to produce a geolocation file for the images which could then be imported to Pix4d etc. would do the trick.
KAP log file attached in case of any use/interest to anyone.
Thanks very much...
