Payload model for the camera that can interface with Unreal and produce images. This class is able to take imagery of different kinds and store the data as byte arrays.
Properties
| Declared | Description |
|---|---|
| Aperture | The diameter of the opening of the lens, larger opening means wider FOV. |
| ApertureFStops | The ratio of the focal length to the aperture diameter, larger ratiomeans wider FOV. |
| CanCaptureFlag | A flag for if the camera can autonomously capture an image |
| CircleOfConfusion | Defines the acceptable level of blur, light from an object converging before orafter the sensor will be out of focus, if it is blurred by more than the circleof confusion it is not inside the depth of field planes this is measured on thesensor itself in this case. |
| DepthOfField | The distance from the camera to the depth of field plane |
| DepthOfFieldFar | The distance from the camera to the far depth of field plane |
| DepthOfFieldNear | The distance from the camera to the near depth of field plane |
| EventCameraDataNum | Tracks the number of events that have been captured by the camera since becoming an event camera |
| FieldOfView | The Field Of View (FOV) of the camera |
| FileName | The name of the image that will be saved whenthe image is captured. |
| FocalLength | The Distance from the nodal point (where light converges) of the lens to the sensor,longer distance confines field of view. Moving the sensor closer to the nodal pointwill catch more light and increase field of view. |
| FocusingDistance | Defines the distance from the lens to where objects are in focus |
| HyperFocalDistance | Closest distance where focusing here will make everything beyond half the distance sharp(sharp as defined by circle of confusion). |
| IsEvent | Defines whether the camera will capture events as a Neuromorphic Camera, which are pixelsthat have changed over time from the previous capture. |
| IsMonochromatic | Defines whether the camera is monochromatic or not |
| LastSampleEventCameraDataNum | Tracks the number of events that have been detected by the camera in the previous capture |
| NextSample | The previous time that a camera was sampled |
| Out_CameraConfigMsg | The output message that contains the configuration of the camera. |
| Out_CameraImageMsg | An output message that contains the data from the imageand is able to store all the bytes. |
| PixelPitch | The spacing from one pixel to its X or Y neighbour, center to center.A smaller pixel pitch and resolution reduces the physical size of thesensor resulting in a more cropped image. |
| ReadyToCapture | A flag for if the image is ready to capture |
| Resolution | The Resolution of the camera sensor |
| SampleRate | The time between photo captures. If the sample rate is 0 or less constantly capture. |
| SensorSize | The physical size of the sensor, based on the focal distance. |
