First impression of the mi sphere (xiaomi mijia 360) .
I have experience making Mapillary images with the xaomi yi (xiao yi) actioncam and also with the LG360 cam that I won in the Mapillary contest. I will compare the mi sphere with these 2 every now and then when it comes to the specific needs for Mapillary. If you want to know more about the mi sphere itself I suggest you google around or maybe just read this first so you know all about the specs and image quality of this device.
Make sure you use a micro sd card that can write fast. I use the Samsung Evo plus that should write at a speed op 90/MB sec.
The camera can record while charging. The photo time lapse options are 2, 5, 10,30, 60, 120 and 300 seconds. The 2 second interval however is in reality a little more than 4 seconds. I’ve tested the 2 sec interval mode in home and ourdoors but for some reason it stops after a while . The camera shuts down and reboots.
The camera can shoot video which can be used for uploading to the Mapillary. Unfortunately the video upload site is not able to display video. It does play audio but there is nothing to see so it is impossible to upload a video that is in sync with the GPX track. I do not know why this happens. With the LG360 it has not been any problem.
All mentioned cameras have a button on it that toggles between video and photo mode. The cheapest camera of them all (the xiao yi) is the only one that stores the photo mode settings in the camera (like time lapse 2 seconds) so you don’t have to use you smartphone and adjust the photo mode. It is a shame that you have to use a wifi device to set the camera to time lapse mode every time you switch the camera on. Especially with the Mi Sphere that reboots in timelape photo mode this is very annoying
Both the Mi Sphere and the LG360 can record location but this is only done when connected to a device with gps. The camera themselves do not have GPS recording abilities. I have not tried this yet with the mi sphere.
Unlike the LG360 the mi sphere does not stitch the images in the camera. For stitching you have to use the app on your smartphone or alternatively use the PC software. I use the latter because of the quantity of the images. I insert the micro sd card in my laptop and stitch the photos. This takes quite some time and is an extra step compared to the LG360. The software is a bit buggy. It crashes every now and then. The good news is that it is worked on so a better version should be available any time soon.
Video stitching is also not done in the camera but should be done with the app or the PC application.
I’m used to adding GPX info an uploading the images via Python scripts. Yesterday I tried to upload a 84 image sequence. Unfortunately it did not work. Images were uploaded but the script reported 0 for the “succes” and also 0 for the “failed”. I’ve reported this to support and hope they can sort this out.
I did manage to upload 1 image via manual upload. That worked just fine. On the same location you can also see an imaged that was made with my LG360. You can see there is a big difference.
