Detect Vertex

Function

This Step manually sets an ROI that contains the line segment to detect, and this Step will detect a vertex and output its info.

Usage Scenario

This Step is generally used to find the vertices of objects in the measurement scenarios.

Input and Output

  • Input:

  1. An object vertex will be extracted in the ROI of image input at this port.

  2. 2D transformation input at this port is used to transform the ROI set in a previous execution to the appropriate position.

  • Output:

  1. Visualize the image, which can display the edge points, ROI borders, vertex, and baseline according to parameter settings.

  2. Pixel-wise coordinates of the vertex.
