mmocr.utils.bezier2polygon

mmocr.utils.bezier2polygon(bezier_points, num_sample=20)

Sample points from the boundary of a polygon enclosed by two Bezier curves, which are controlled by bezier_points.

Parameters

• bezier_points (ndarray) – A \((2, 4, 2)\) array of 8 Bezeir points or its equalivance. The first 4 points control the curve at one side and the last four control the other side.

• num_sample (int) – The number of sample points at each Bezeir curve. Defaults to 20.

Returns

A list of 2*num_sample points representing the polygon extracted from Bezier curves.

Return type

list[ndarray]

Warning

The points are not guaranteed to be ordered. Please use mmocr.utils.sort_points() to sort points if necessary.
