FAQ - Troubleshooting
Problem | Possible Reasons | Solution |
|---|---|---|
Processing time is long | Hardware | |
Only very few or no points were extracted | Not enough images | Each point should be present in at least 3 overlapping images. More are better. |
No texture | Texture on the object is required to enable image matching. Overexposed, underexposed, blurry images or surfaces without texture will lead to low quality, or missing parts in the point cloud. Texture can be projected artificially, but must be stable between the images. | |
Insufficiently precise orientation | Dense image matching relies on precise orientation data as input. If the orientation does not satisfy the required precision, matching results will degrade. | |
Resolution on the object is low (point density, depth resolution) or noisy surfaces | Not enough Images | Each point should be present in at least 3 overlapping images. More are better. |
Processing Level too low | Use “--quality ULTRA” to run the processing on full resolution. | |
Image Orientation Quality too low | The quality of the image orientation directly impacts the quality of the surface reconstruction. Improve the bundle adjustment outcome with your orientation software (e.g. rejecting outlier points) | |
Shifts between the point clouds | Image Orientation quality too low | See above. |
Graphics card (GPU) is not in use | Parameters | Activate graphics card use in Preferences or in command line with --gpu |
Hardware | Make sure the GPU is Nvidia CUDA compatible with Compute Capability 3.2 or higher | |
Driver issues | Make sure, that latest Nvidia drivers are installed and that the CUDA Driver Timeout settings have been adjusted | |
Failed to connect to the license server | No Internet connection | SURE needs to re-validate its activation status periodically. For the validation procedure a connection to the Internet is required. If no Internet connection is available, there will be a grace period of up to two weeks during which SURE can still be used. Afterwards, a re-validation of the software is required. |
Invalid proxy settings | If your connection to the Internet goes through a proxy server, SURE will try to read and use the proxy settings which are set for the Microsoft Edge browser. In order to set a custom proxy server, please use SURE's command line interface with one of the following options:
| |
Connection blocked by firewall or anti-virus software | Please open a web browser and navigate to https://wyday.com/. Use the Microsoft Edge browser, if possible. If there are problems loading this website, this is the source of the problem. Please try to deactivate the firewall, anti-virus, or anti-malware software which is blocking the connection or add the SURE executables (SURE.exe as well as the SURE Module's executables, and potentially the TurboActivate.exe) to their whitelist (or exclude it from whatever filtering that/those program(s) are doing). | |
Missing SHA-2 Certificate | Since the release SURE version 2.0, an SHA-2 certificate is required for the communication with the activation servers. Make sure that this certificate is available on your system and/or the proxy the internet connection goes through. | |
Found disabled network adapters | For the licensing mechanism, SURE creates a hardware fingerprint. Part of this fingerprint are the properties of network adapters. To enable activation the following steps can be undertaken:
If this is not successful and you have more network adapters that are activated but not connected to the internet, please deactivate the network adapters from the BIOS. | |
Activation fails on Linux | Elevated rights required | On Linux the license activation requires superuser permissions. Try sudo SURE -activate <key> |
Activation fails because a virtual machine is detected although none is used | Hyper-V activated |
How to disable Hyper-V (Control Panel > Programs > Turn Windows Features on or off) and disable the following Windows features |
Image Viewer / Camera Stations / Mesh Editor crashes | Windows RDP session | The Windows remote desktop session (via RDP) does not support rendering of OpenGL content. Since these modules (Image Viewer, Camera Stations, Mesh Editor) use OpenGL content, running SURE via RDP session can cause timeouts and/or crashes of the software. |
SURE is detected as Malware | Detected by the Antivirus | Please whitelist it, make it as a trusted software in the Antivirus your PC has. |
