Camera Models Description
This page describes the different camera models that can be used to render the camera behavior in Speos.
To simulate the behavior of a camera, you can create an irradiance simulation containing the complete optical system of the camera, or you can create a camera simulation containing only the camera model.
The camera model allows you to render the behavior of the complete camera system, that is how light is going to propagate through the lens system.
In Speos, three models with different levels of complexity are available to imitate the behavior of a camera. The complexity of the models is based on the number and variety of inputs they consider/contain.
The models are described in an *.OPTDistortion file, used as input of the camera sensor.
- perform fast simulations of the camera behavior (compared to simulating the complete camera system)
- reproduce most of the real lens properties
- perform simulation without exposing the manufacturer intellectual properties
Basic Distortion Curve (V1)
The first model describes the angular relationship between the incoming ray's angle and the output ray's angle. This relationship is called Distortion Curve.
The basic model assumes that the origin (entrance pupil point) is fixed and the lens has a revolution symmetry.
Speos Lens System (V2)
*.OPTDistortion Binary File
The *.OPTDistortion binary file is the more complex distortion file as it also consider chromatic and geometric aberrations. The lens data model described in the *.OPTDistortion file is generated from a complete camera system created in Zemax OpticStudio.
