lensprofiler

lensprofiler application implements a workflow to create lens profiles, that can be used together with IFF SDK. It shares most of the C++ code with imagebroker example IFF SDK application, but also includes ldc.py Python script for chessboard target auto-detection and radial lens distortion model estimation, which is based on the source code provided with Algebraic Lens Distortion Model Estimation article by Luis Alvarez, Luis Gomez, and J. Rafael Sendra published in Image Processing On Line journal. Application is located in samples/06_lens directory of the IFF SDK package. It comes with example configuration files (lensprofiler.json and res/ldc.json) suited for XIMEA cameras and standard 10x7 chessboard target (such as included res/chessboard.png). See linux and windows directories for helper scripts to install required dependencies (e.g. OpenCV library). Operation is controlled using a keyboard:

• 1 decreases exposure
• 2 increases exposure
• Tab captures an image and starts the profile generation procedure (further instructions are shown on the screen)
