Concept definition

template<typename D>
concept calib::distortion_model = 
    requires(const D& distortion, const Eigen::Matrix<typename D::Scalar, 2, 1>& point2d) {
        {
            distortion.template distort<typename D::Scalar>(point2d)
        } -> std::same_as<Eigen::Matrix<typename D::Scalar, 2, 1>>;
        {
            distortion.template undistort<typename D::Scalar>(point2d)

    }

Detailed Description

Concept defining the interface for lens distortion models.

A distortion model must provide both forward distortion and inverse undistortion operations for normalized 2D coordinates. This concept ensures type safety and compile-time verification of distortion model implementations.

Template Parameters

D	The distortion model type

Requirements:

• Must have a Scalar type member
• Must provide distort() method for forward mapping
• Must provide undistort() method for inverse mapping
