So I have been surveying with my Samsung S10 on my bike for a couple of weeks now using the Android Mapillary app and the Mapillary supplied bike mount. What can I say? I’m totally disappointed of the results. Around 1/3 of the pictures I have discarded completely. Of the remainder I have uploaded many despite them being blurred or out of focus.
In full daylight and on smooth surfaces I get quite good results (apart from some 180° rotated images). But with rough road surface, overcast weather, bright sunlight or at dawn I tend do get lousy results.
The app seems to prioritize high illumination and low ISO speed. I don’t know if that are general technical limitations for an Android app or if the Mapillary app is limited. All images are taken with f1.5 aperture despite my main camera also offering f2.3. The latter would even give a better depth of field. Instead of increasing the ISO speed or living with darker images the app increases exposure time so that pictures get blurry when riding on rougher ground. On top of that many images are out of focus in not ideal light conditions.
I have played around with some of the few available settings in the app but could not see any significant difference in the results.
Did you guys make the same experience? Is it the app or my phone (I would think the camera of this phone would not be a problem but who knows)? Is there any way to tweak the settings more, force shorter exposure times, improve focusing?
Or should I say goodbye to the Mapillary app and try a different workflow? Any recommendations? I have also installed OpenCamera now but still stick to the Mapillary app for its easy upload and because it dims the display during capturing. But are there any good alternatives I should try?
