Struct rerun::sdk::components::PinholeProjection

pub struct PinholeProjection(pub Mat3x3);

Component: Camera projection, from image coordinates to view coordinates.

Child from parent. Image coordinates from camera view coordinates.

Example:

1496.1     0.0  980.5
   0.0  1496.1  744.5
   0.0     0.0    1.0

Implementations

impl PinholeProjection

pub fn from_focal_length_and_principal_point( focal_length: impl Into<Vec2D>, principal_point: impl Into<Vec2D>, ) -> PinholeProjection

Create a new pinhole projection matrix from a focal length and principal point.

pub fn with_principal_point( self, principal_point: impl Into<Vec2D>, ) -> PinholeProjection

Principal point of the pinhole camera, i.e. the intersection of the optical axis and the image plane.

see definition of intrinsic matrix

pub fn focal_length_in_pixels(&self) -> Vec2D

X & Y focal length in pixels.

see definition of intrinsic matrix

pub fn principal_point(&self) -> Vec2

Principal point of the pinhole camera, i.e. the intersection of the optical axis and the image plane.

see definition of intrinsic matrix

pub fn project(&self, pixel: Vec3) -> Vec3

Project camera-space coordinates into pixel coordinates, returning the same z/depth.

pub fn unproject(&self, pixel: Vec3) -> Vec3

Given pixel coordinates and a world-space depth, return a position in the camera space.

The returned z is the same as the input z (depth).

pub fn fov_y(&self, resolution: impl Into<Resolution>) -> f32

Field of View on the Y axis, i.e. the angle between top and bottom (in radians).
