HALCON Library
Bug Fixes
3D
The procedures check_dl_preprocess_param, preprocess_dl_dataset, and gen_dl_samples did not treat the parameter 'min_visibility' correctly, leading to errors in the detection training in example deep_3d_matching_training_workflow.hdev. This problem has been fixed.
For open_scene_engine, the default timeout of 10 seconds was insufficient on some systems. The default timeout has been increased to 60 seconds.
The procedure set_scene_engine_run_param sometimes threw error 1401 ("Wrong number of values of control parameter 1") in operation 'max'. This problem has been fixed.
Installation
The installation of the package "Deep Learning Core" erroneously did not depend on the installation of "Microsoft Visual C++ Redistributable". This problem has been fixed.
Third-Party Libraries
When using the mimalloc memory allocator, memory leaks could occur under some circumstances. This problem has been fixed by updating mimalloc to version 2.2.4.
Errata Release Notes
Various release notes were missing in HALCON 25.05. This problem has been fixed.
