ImageReader
Recursively iterate over the images in a directory. Skips an image if it already exists in the database. Extracts the camera intrinsics from EXIF and writes the camera information to the database.
Optional root path to folder which contains image masks. For a given image, the corresponding mask must have the same sub-path below this root as the image has below image_path. The filename must be equal, aside from the added extension .png. For example, for an image image_path/abc/012.jpg, the mask would be mask_path/abc/012.jpg.png. No features will be extracted in regions where the mask image is black (pixel intensity value 0 in grayscale).
default: SIMPLE_RADIAL
possible: SIMPLE_PINHOLE, PINHOLE, SIMPLE_RADIAL, RADIAL, OPENCV, OPENCV_FISHEYE, FULL_OPENCV, FOV, SIMPLE_RADIAL_FISHEYE, RADIAL_FISHEYE, THIN_PRISM_FISHEYE
Name of the camera model.
See: Camera Models
default: 0 (disabled)
Whether to use the same camera for all images.
default: 0 (disabled)
Whether to use the same camera for all images in the same sub-folder.
default: 0 (disabled)
Whether to use a different camera for each image.
default: -1
Whether to explicitly use an existing camera for all images. Note that in this case the specified camera model and parameters are ignored.
Manual specification of camera parameters. If empty, camera parameters will be extracted from EXIF, i.e. principal point and focal length.
default: 1.2
If camera parameters are not specified manually and the image does not have focal length EXIF information, the focal length is set to the value default_focal_length_factor * max(width, height).
Optional path to an image file specifying a mask for all images. No features will be extracted in regions where the mask is black (pixel intensity value 0 in grayscale).
