| Description: The model_type attribute specifies an identifier for the type or kind of model. The value should be one of a well defined set, providing an application program with sufficient information to know how to handle the rest of the parameters within the model. This value will correlate directly with the specific camera model class that is a subclass of the Camera_Model_Parameters class. |

| | CAHV | The CAHV model is a linear, perspective-projection camera model (equivalent to a pinhole camera). |
| | CAHVOR | The CAHVOR model is built upon CAHV (see CAHV_Model), adding radial (barrel or pincushion) distortion to the linear model. |
| | CAHVORE | The CAHVORE model is built upon CAHVOR (see CAHVOR_Model), adding support for fisheye lenses. |
| | PSPH | The PSPH model is designed to perform better fisheye-image rectification prior to 1D stereo correlation. |
