High-precision
measurements
in aerial images

Measuree automatically identifies all images that contain the object you are looking for and displays them well arranged and in order of relevance or naming.

In an intuitive way, Measuree offers you high-precision measurements in aerial images, regardless of whether they were taken with high-end multiperspective systems or simpler drone cameras.

It is straightforward: Mark the desired object in two images and you will receive valid and precise 3D coordinates.

With Measuree, you can always keep track of your measurement data thanks to clear presentation, intelligent image filters and a hierarchical object model.

• No installation on workstations required - a modern web browser is sufficient
• Session persistence: continue working after restarting Measuree, the browser or even the computer
• Familiar functions such as undo/redo (with the entire session's workflow), drag & drop, keyboard shortcuts and context menus
• Layers and objects: hierarchical object model
• Available in various languages ​​(currently German, English and Italian, new languages ​​can be added at any time)

• Suitable for different flight platforms (airplane, drone) and sensor systems (nadir, oblique and multiperspective; thermal infrared, hyperspectral)
• Support for digital and (scanned) analog aerial images (historical flights)
• Synchronization of different flight data sets (e.g. different flight years) to visualize terrain and construction changes

• Customizability of the multi-view layout (resize, duplicate, split)
• Working with multiple monitors: individual views (windows) of Measuree can be distributed across different monitors
• Taking screenshots for the creation of documents (e.g. reports)
• Adaptation of image display
  (brightness, contrast, saturation and hue)
• View centering on crosshairs or known position (2D or 3D)
• Display image trigger points and image covers
  

• Most precise measuring method by intersecting the viewing rays from two or more different perspectives (images) - no time-consuming and costly calculation of a 3D mesh required - thus extremely short time to first measurement
• Display of measurement uncertainty based on reprojection errors and intersection angles for quality assurance
• Display of monoplot viewing rays for fast 3D measurement
• Automatic determination of segment lengths and distances (3D)
• Filtering of measurement points according to data quality
• 3D auxiliary lines allow the reconstruction of hidden object points

• Grouping of objects into nestable levels
  (e.g. streets / houses / components)
• Object types: point, line, polyline, polygon
• Configurable layer prototypes for semantic markup of data
• Automatic determination of area measurements with base area, inclination angle and azimuth angle
• Expanding/collapsing levels and objects to improve clarity when dealing with large amounts of data
• Change of color and visibility per object or level
• Locking correct points and objects to avoid erroneous modification
• Possibility to assign freely definable attributes for measurement points
  (e.g. quality criteria)
• Import/Export of individual objects or levels

• Automated detection of all images that contain one or more objects in whole or in part ("object footprints"). These images can be selected for further processing in Measuree or exported as a list.

Sometimes aerial images contain sensitive objects that must not be accessible to the public (e.g. military facilities, power plants). Automated localization of such objects is a major challenge, especially in oblique images.

Measuree offers a tailored solution here:

1. Automated detection of all images in which these objects are at least partially contained (object footprints, see above).
2. Automated declassification to generate new images from the original nadir or oblique aerial images in which the selected objects are removed or rendered unrecognizable (blackening, pixelation, blurring).
