Path to a GeoTIFF DEM or a LAS/LAZ point cloud that the reconstruction outputs should be automatically aligned to. Experimental. Default: None

auto-boundary

Automatically set a boundary using camera shot locations to limit the area of the reconstruction. This can help remove far away background artifacts (sky, background landscapes, etc.). See also –boundary. Default: False

auto-boundary-distance <positive float>

build-overviews

Build orthophoto overviews for faster display in programs such as QGIS. Default: False

camera-lens auto | perspective | brown | fisheye | fisheye_opencv | spherical | equirectangular | dual

Set a camera projection type. Manually setting a value can help improve geometric undistortion. By default the application tries to determine a lens type from the images metadata. . Default: auto

crop <positive float>

Automatically crop image outputs by creating a smooth buffer around the dataset boundaries, shrunk by N meters. Use 0 to disable cropping. Default: 3

dem-decimation <positive integer>

Decimate the points before generating the DEM. 1 is no decimation (full quality). 100 decimates ~99%% of the points. Useful for speeding up generation of DEM results in very large datasets. Default: 1

dem-euclidean-map

Computes an euclidean raster map for each DEM. The map reports the distance from each cell to the nearest NODATA value (before any hole filling takes place). This can be useful to isolate the areas that have been filled. Default: False

dem-gapfill-steps <positive integer>

Number of steps used to fill areas with gaps. Set to 0 to disable gap filling. Starting with a radius equal to the output resolution, N different DEMs are generated with progressively bigger radius using the inverse distance weighted (IDW) algorithm and merged together. Remaining gaps are then merged using nearest neighbor interpolation. Default: 3

dem-resolution <float>

DSM/DTM resolution in cm / pixel. Note that this value is capped by a ground sampling distance (GSD) estimate. Default: 5

dsm

feature-type akaze | dspsift | hahog | orb | sift

Choose the algorithm for extracting keypoints and computing descriptors. . Default: dspsift

force-gps

Use images’ GPS exif data for reconstruction, even if there are GCPs present.This flag is useful if you have high precision GPS measurements. If there are no GCPs, this flag does nothing. Default: False

geo <path string>

Path to the image geolocation file containing the camera center coordinates used for georeferencing. If you don’t have values for yaw/pitch/roll you can set them to 0. The file needs to use the following format: EPSG:<code> or <+proj definition>image_name geo_x geo_y geo_z [yaw (degrees)] [pitch (degrees)] [roll (degrees)] [horz accuracy (meters)] [vert accuracy (meters)]Default: None

gltf

Generate single file Binary glTF (GLB) textured models. Default: False

gps-accuracy <positive float>

Set a value in meters for the GPS Dilution of Precision (DOP) information for all images. If your images are tagged with high precision GPS information (RTK), this value will be automatically set accordingly. You can use this option to manually set it in case the reconstruction fails. Lowering this option can sometimes help control bowling-effects over large areas. Default: 3

help

show this help message and exit

ignore-gsd

Ignore Ground Sampling Distance (GSD).A memory and processor hungry change relative to the default behavior if set to true. Ordinarily, GSD estimates are used to cap the maximum resolution of image outputs and resizes images when necessary, resulting in faster processing and lower memory usage. Since GSD is an estimate, sometimes ignoring it can result in slightly better image output quality. Never set –ignore-gsd to true unless you are positive you need it, and even then: do not use it. Default: False

matcher-neighbors <positive integer>

Perform image matching with the nearest images based on GPS exif data. Set to 0 to match by triangulation. Default: 0

matcher-order <positive integer>

Perform image matching with the nearest N images based on image filename order. Can speed up processing of sequential images, such as those extracted from video. It is applied only on non-georeferenced datasets. Set to 0 to disable. Default: 0

mesh-size <positive integer>

The maximum vertex count of the output mesh. Default: 200000

min-num-features <integer>

Name of dataset (i.e subfolder name within project folder). Default: code

no-gpu

pc-las

Export the georeferenced point cloud in LAS format. Default: False

pc-quality ultra | high | medium | low | lowest

Set point cloud quality. Higher quality generates better, denser point clouds, but requires more memory and takes longer. Each step up in quality increases processing time roughly by a factor of 4x.. Default: medium

pc-rectify

Perform ground rectification on the point cloud. This means that wrongly classified ground points will be re-classified and gaps will be filled. Useful for generating DTMs. Default: False

pc-sample <positive float>

Filters the point cloud by keeping only a single point around a radius N (in meters). This can be useful to limit the output resolution of the point cloud and remove duplicate points. Set to 0 to disable sampling. Default: 0

When processing multispectral and thermal images you should set this option to obtain reflectance/temperature values (otherwise you will get digital number values). [camera] applies black level, vignetting, row gradient gain/exposure compensation (if appropriate EXIF tags are found) and computes absolute temperature values. [camera+sun] is experimental, applies all the corrections of [camera], plus compensates for spectral radiance registered via a downwelling light sensor (DLS) taking in consideration the angle of the sun. .

Override the rolling shutter readout time for your camera sensor (in milliseconds), instead of using the rolling shutter readout database. Note that not all cameras are present in the database. Set to 0 to use the database value. Default: 0

sfm-algorithm incremental | triangulation | planar

Choose the structure from motion algorithm. For aerial datasets, if camera GPS positions and angles are available, triangulation can generate better results. For planar scenes captured at fixed altitude with nadir-only images, planar can be much faster. . Default: incremental

skip-band-alignment

When processing multispectral datasets, ODM will automatically align the images for each band. If the images have been postprocessed and are already aligned, use this option. Default: False

use-exif

Use this tag if you have a GCP File but want to use the EXIF information for georeferencing instead. Default: False
