Inputs

Pandora works with two stereo rectified one-channel or multi-channel images.

Configuration and parameters

Name Description Type Default value Required
img_left Path to the left image string Yes
img_right Path to the right image string Yes
nodata_left Nodata value for left image int -9999 No
nodata_right Nodata value for right image int -9999 No
disp_min Minimal disparity int or string Yes
disp_max Maximal disparity int or string Yes
left_mask Path to the left mask string none No
right_mask Path to the right mask string none No
disp_min_right Path to the minimal disparity grid of the right image string none No
disp_max_right Path to the maximal disparity grid of the right image string none No
left_classif Path to the left classification map string none No
right_classif Path to the right classification map string none No
left_segm Path to the left segmentation map string none No
right_segm Path to the right segmentation map string none No

Images

  • If the input images are multiband, the band's names must be present on the image metadata. To see how to add band's names on the image's metadata, please see faq.
  • Only one-band masks are accepted by pandora. Mask must comply with the following convention :
    • Value equal to 0 for valid pixel
    • Value not equal to 0 for invalid pixel
  • For more details please see as_an_api images subsection

Note

- Parameters disp_min and disp_max can be the disparity range (type int) or the path to the grids that contain the minimum and maximum disparity of a pixel (type string). - If disp_min and disp_max are integers, then the range of disparities is fixed. The minimal and maximal disparity of the right image are automatically calculated : disp_min_right = - disp_max and disp_max_right = - disp_min. - If disp_min or disp_max are strings, that means they are paths to grids of disparities which have the same size as the input images. Each pixel (x,y) of the grid corresponds to a local disparity (min for disp_min and max for disp_max) related to the same pixel (x, y) of the image. - Cross-checking step is not applicable if only left grids are provided (i.e the right one must be provided).
