[−][src]Function opencv::core::polar_to_cart

pub fn polar_to_cart(
    magnitude: &dyn ToInputArray, 
    angle: &dyn ToInputArray, 
    x: &mut dyn ToOutputArray, 
    y: &mut dyn ToOutputArray, 
    angle_in_degrees: bool
) -> Result<()>

Calculates x and y coordinates of 2D vectors from their magnitude and angle.

The function cv::polarToCart calculates the Cartesian coordinates of each 2D vector represented by the corresponding elements of magnitude and angle: block formula

The relative accuracy of the estimated coordinates is about 1e-6.

Parameters

  • magnitude: input floating-point array of magnitudes of 2D vectors; it can be an empty matrix (=Mat()), in this case, the function assumes that all the magnitudes are =1; if it is not empty, it must have the same size and type as angle.
  • angle: input floating-point array of angles of 2D vectors.
  • x: output array of x-coordinates of 2D vectors; it has the same size and type as angle.
  • y: output array of y-coordinates of 2D vectors; it has the same size and type as angle.
  • angleInDegrees: when true, the input angles are measured in degrees, otherwise, they are measured in radians.
