CVTOOLS is a c++ software library designed for industrial computer vision. It is made of six modules, each with specific functionalities.
-
CVIP
The CVIP (Image Processing) module contains functions for sub-pixel edge detection, both threshold-based and gradient based, chessboard detection and features labelling, image morphological operation, image averaging, image format change, image binarization via different types of thresholding, (laser) stripes detection, blob labelling and analysis, perspective image warp.
All these function are optimized via SSE and parallelization.
-
CVTC
The CVTC (Telecentric Calibration) module contains a set of functions for calibration of telecentric lens based system. You can also find functions for distortion elimination, both from the entire image and from edge coordinates. Some diagnostic functions let you obtain distortion and residual calibration error map, in order to evaluate the calibration results.
-
CVPM
The CVPM (Pattern Matching) module contains functions for edge-based pattern matching: you can learn a model by a set of edges, save it and load it, and match it to a new set of edges. These functions are very fast, accurate and reliable. You can use these functions in order to find multiple occurrencies of the same model in the image, or multiple models.
-
CVPH
The CVPH (Pinhole) module contains functions for fixed-focal-length lens calibration, toghether with perspective plane calibration. You'll be able to both undistort and unwarp a working plane with very fast operations, for real-time applications.
-
CVMETRIC
The CVMETRIC module contains optimized functions for fitting of circles and lines on edge points, and functions for borders intersection. Functions for geometric models intersection are available too.
-
CV360
The CV360 (360 Lens) module contains functions for calibration/configuration and rectification of 360 lens images.
See the CVTOOLS flyer.
Download the latest stable version of the CVTOOLS library. The installation package includes the library binaries, includes and a c# wrapper,
together with sample applications:
- CVRULER for telecentric calibration (to be used for generation of calibration files) an measurements on offline images
- PMAPP for pattern matching test on offline images
- PerspectiveWarp for perspective warp algorithm test on offline images
- PHCALIB for calibration of fixed focal length lens (to be used for generation of calibration files)
- PolyViewApp for rectification of polyview and micro-polyview lens (to be used for generation of configuration files)
