Q: Geotagging of RAW images:
Geotagging was only tested so far with the JPEG images. We experienced so far that image quality does not differ so much between RAW and JPEG images and that most people anyways want to use JPEG images for the post processing since the amount of data handling raw files makes the entire process very slow. At the moment we do not plan to work on enabling geotagging of RAW images but we could imagine that it would be possible to copy geotags from the JPEG images to the corresponding RAW images by another tool.
Q: RAW images for QX1 camera:
We do not recommend to take RAW images with QX1 camera during flight. In the case of low trigger distance taking raw images with the QX1 however might be not feasible in the current configuration. The write speed of the image files is too low so that triggered images are actually not taken.
Q: Geotagging: Workaround to tag images if you forgot to tag after flight (1 or several flights)
At the moment the tagging can fail if there are images from several flights. Please start the geotagging always after flight - it runs in the background, you can start planning the next flight while geotagging is running (if you have a second SD card you can even start the next flight in parallel). For the flights for which tagging failed you can use the following workaround to tag your images:
- Make sure you got the Flight Logs of the flight(s) in WingtraPilot —> Geotagging —> “Select Flight”. If the log of the last flight is missing, you can power on WingtraOne and you will be asked if you want to download the log now. Logs of older flights are lost permanently.
- If you want to geotag images of several flight: Divide the original images manually into the different flights and save them into separate folders on the SD card. If the geotagging has already been run without success you can find the original images in the /ORIGINAL folder.
- Start the tagging in WingtraPilot for every flight separately by selecting the respective flight from the list and the respective folder and clicking on “Start Tagging”.
Q: no images after flight (not even preflight images)
Missing images from an entire flight only occur if there has been no or a wrongly inserted SD card in the camera. For WingtraOne QX1 you should hear a distinct shutter click when the camera is taking images in the pre-flight routine. On WingtraOne RX1 you can actually see the image counter on the camera screen when opening the top cover. If you cannot confirm the images are taken, remove and insert the SD card to the camera again and repeat the camera image test sequence by repowering WingtraOne.
Q: no images after flight (but pre-flight images are there)
This problem has never occurred to us before. There are two scenarios where this could happen. First the SD card is full and there is no additional free space to save images by the camera. Please make sure that there is enough space on the SD card inside the camera. The second scenario is that if you changed camera settings after the camera test picture process is finished and left the camera ON for takeoff, the camera will be switched off again in the first waypoint, resulting in no picture will be taken throughout the whole flight. Hence, remember to always switch OFF the camera if you change the camera settings after the camera test picture process is finished.
Q: Missing individual camera images:
The Sony QX1 camera is limited to roughly 1 image/s. If the trigger distance get’s even shorter then it can eventually happen that individual triggers are not actually capturing an image on the camera.
Q: Blur in images:
Feature in image corner:
Features which are outside of the center of the image suffer from optical limitations of the lense which is used in the Wingtra One system. In particular in low light conditions at open aperture the lens is not capable of imaging sharply in the corners. To compare image quality and sharpness, please use only features in the center of the images. The map quality can be improved significantly in these situations if the overlap between images is increased.
Non perfect Focus:
Sharp camera images usually show a gradients between different colors which are 2-3 pixel wide. If you observe blurry images with color or contrast gradients of more than 5 pixel size that indicates wrong focus adjustment. Please refer to the FAQ for WingtraOne 20MP QX1 Troubleshooting or WingtraOne 40MP RX1 Troubleshooting to get help on refocusing the camera.
