To verify that the image quality is sufficient, visualize the images and check that:

1. The images are not blurry. If the images are blurry, check the camera settings (Step 1. Before Starting a Project > 2. Configuring the Camera Settings) and acquire a new dataset.
2. The images have enough image content. Image have not enough content if the scene contains for example water, mirror or glass surfaces. In such cases, capturing a dataset by flying higher might help.
3. The images have sufficient resolution. Small images (e.g. 640x480 pixels) have few content.

• If possible acquire images of a higher resolution.
• If not, set the Image Scale for feature extraction to 2 (Double image size) in the Processing Options (Menu Process > Processing Options... > 1. Initial Processing > General).
