@page cameramodel_mainsection Intrinsic Camera Models

@note SW Release Applicability: This module is available in both **NVIDIA DriveWorks** and **NVIDIA DRIVE Software** releases.

## Introduction

Camera sensors and lenses influence the transformation of an observed point in the three-dimensional world into the two-dimensional image plane. The intrinsic camera models detailing these transformations in NVIDIA<sup>&reg;</sup> DriveWorks are described in @ref rig_configuration_group. 

This module provides methods to initialize a particular camera model, use it to provide pixel-to-ray and ray-to-pixel transformations, and other helper functions. 

For details on obtaining suitable model parameters for a particular camera, see the DriveWorks @ref dwx_camera_calibration documentation.
