pyorc - v0.8.8

[0.8.8] = 2025-07-14

Added

Changed

Deprecated

Removed

Fixed

• issues with plotting cross sections in edge cases with water levels equal to lowest point or above highest point
• fixed problem with situations where either the cross section data from a shapefile or the camera configuration did not contain CRS information. This is now correctly parsed when creating a CrossSection instance.

pyorc - v0.8.7

[0.8.7] = 2025-06-30

Added

• CLI option --cross_wl
• A new 3-point bounding box estimation, ideal for selecting a bounding box in strongly oblique cases. First select left bank, then right bank, then a point up- or downstream from the selected line for the size of the bounding box.
• rvec and tvec are written to camera configuration after fitting. ### Changed
• CLI option --cross_wl now replaces --cross for optical water level estimation. --cross is only used for discharge calculation
• Plotting in camera objective is accelerated
• water level detection with CrossSection.detect_water_level can now consume either min_z and max_z (for levels in the original coordinate system) or min_h and max_h (for levels using the local h_ref datum if provided). These minimum and maximum levels can be used to pre-condition the level range that the algoithm will seek in.
• Pose fitting can now be performed with a pre-defined camera matrix and set of distortion coefficients. This is very useful when a user has already pre-calibrated these parameters. It will improve the fit of the rvec and tvec, i.e. rotation and translation vectors.
• Changed code coverage reporting from Codecov to sonarqube for code coverage reports. Codecov caused issues with numba code. ### Deprecated ### Removed ### Fixed
• incorrect estimation of optical water level if bank="near" was used. This resulted in only a smaller portion of the cross section being used. Now the full nearby side is used.

pyorc - v0.8.6

This release allows for pre-fixing camera lens parameter including focal length and the k1 and k2 radial distortion. When these parameters are provided on command line, the camera matrix and distortion coefficients are not optimized but fixed instead. If only one or two parameters, or none at all are provided, the remainder parameters will be estimated through optimization.

A small bug fix was also made in the reading of geojsons without CRS. This is now possible without resulting in any errors.

pyorc - v0.5.0

What's Changed

Several large updates were made to:

• make it a lot easier to get well-calibrated ground control and lens parameters at the same time. we now do this by optimizing the lens' focal length and (if enough ground control is provided) barrel distortion whilst fitting the perspective to the user-provided ground control points
• provide the fitted ground control points in the interface so that the user can immediately see if the ground control points are well fitted or if anything seems to be wrong with one or more control points.
• get much-improved stabilization for non-stable videos
• feature stabilization on command line which consequently provided user-interfacing to select non-moving areas by pointing and clicking.

The following issues are the major issues describing these major improvements.

The stabilization is arranged slightly differently on the API and can now already be set in camera configuration. This is a change in API requiring a medior version bump.

Added

The most notable change is that the code now includes an automatically installed command-line interface. This will facilitate a much easier use by a large user group. Also the documentation is fully updated to include all functionalities for both command-line users and API users. In detail we have the following additions: - First release of a command-line interface for the entire process of camera configuration, processing and preparing outputs and figures. - Service layer that makes it easy for developers to connect pyorc to apps such as GUIs or dashboards. - Full user guide with description of both the command-line interface and API.

Changed

• Small modifications and additions in the API to accomodate the command-line interface building. ### Deprecated ### Removed ### Fixed
• Bug fixes in the video objects causing videos to sometimes not open properly because of missing frames ### Security
