SOLVEPNP_ITERATIVE = 0

Pose refinement using non-linear Levenberg-Marquardt minimization scheme Madsen04 Eade13

Initial solution for non-planar “objectPoints” needs at least 6 points and uses the DLT algorithm.

Initial solution for planar “objectPoints” needs at least 4 points and uses pose from homography decomposition.

Trait Implementations

impl Clone for SolvePnPMethod

fn clone(&self) -> SolvePnPMethod

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SolvePnPMethod

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<SolvePnPMethod> for i32

fn from(v: SolvePnPMethod) -> Self

Converts to this type from the input type.

impl PartialEq for SolvePnPMethod

fn eq(&self, other: &SolvePnPMethod) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<i32> for SolvePnPMethod

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<Self, Self::Error>

Performs the conversion.
