FromOpenCV
Converts Opaque (OpenCV) data types to Simulink data types
- Library:
Computer Vision Toolbox OpenCV Interface for Simulink
Description
The FromOpenCV block is used to convert the Simulink Opaque (OpenCV) to Simulink data types.
Ports
Inputs
Port_1 — First input signal
scalar | vector | matrix | simulink bus
Input signal to the FromOpenCV block. The input can be of different data types. Each of the input data types determines the output data type of the block.
Data Types: cv_Mat | cv_DMatch | vector_cv_DMatch | vector_vector_cv_DMatch | cv_Rect | vector_cv_Rect | cv_RotatedRect | vector_cv_RotatedRect | cv_TermCriteria | cv_Scalar | cv_Size | cv_Range | cv_Point | cv_Point2f | cv_Point2d | cv_Point3i | cv_Point3f | cv_Point3d | vector_cv_Point | vector_cv_Point2f | vector_cv_Point2d | vector_cv_Point3i | vector_cv_Point3f | vector_cv_Point3d | vector_vector_cv_Point | vector_vector_cv_Point2f | vector_vector_cv_Point2d | vector_vector_cv_Point3i | vector_vector_cv_Point3f | vector_vector_cv_Point3d
Output
Port_1 — Output signal
scalar | vector | matrix | simulink bus
Output signal from the FromOpenCV block.
Data Types: uint8 array | uint16 array | int8 array | int16 array | int32 array | single array | double array | CV_DMATCH_BUS | CV_DMATCH_BUS (1d array) | CV_DMATCH_BUS (2d array) | CV_RECT_BUS | CV_RECT_BUS (1d array) | CV_ROTATEDRECT_BUS | CV_ROTATEDRECT_BUS (1d array) | CV_TERMCRITERIA_BUS | CV_SIZE_BUS | CV_RANGE_BUS | CV_POINT2I_BUS | CV_POINT2F_BUS | CV_POINT2D_BUS | CV_POINT3I_BUS | CV_POINT3F_BUS | CV_POINT3D_BUS | CV_POINT2I_BUS (1d array) | CV_POINT2F_BUS (1d array) | CV_POINT2D_BUS (1d array) | CV_POINT3I_BUS (1d array) | CV_POINT3F_BUS (1d array) | CV_POINT3D_BUS (1d array) | CV_POINT2I_BUS (2d array) | CV_POINT2F_BUS (2d array) | CV_POINT2D_BUS (2d array) | CV_POINT3I_BUS (2d array) | CV_POINT3F_BUS (2d array) | CV_POINT3D_BUS (2d array)
Parameters
DataType — Data type of the Input signal of FromOpenCV block
Point2i (default) | Point2f | Point2d | Point3i | Point3f | Point3d | DMatch | Rect | RotatedRect | Range | TermCriteria | Size | vector<DMatch> | vector<Rect> | vector<RotatedRect> | vector<Point2i> | vector<Point2f> | vector<Point2d> | vector<Point3i> | vector<Point3f> | vector<Point3d> | vector<vector<DMatch>> | vector<vector<Point2i>> | vector<vector<Point2f>> | vector<vector<Point2d>> | vector<vector<Point3i>> | vector<vector<Point3f>> | vector<vector<Point3d>> | Mat | Mat-Image
Use this parameter to specify the input data type of the FromOpenCV block. The table lists the one-to-one mapping of the input versus output data types of the FromOpenCV block.
