Detailed Description

Camera related functions and types.

Macro Definition Documentation

◆ PEAK_INVALID_CAMERA_ID

#define PEAK_INVALID_CAMERA_ID

peak Invalid camera ID value

Use this value for the initialization of variables of type peak_camera_id.

Typedef Documentation

◆ peak_camera_handle

typedef struct peak_camera* peak_camera_handle

peak Camera handle

The camera handle represents an opened camera.
The camera handle is provided by the peak_Camera_Open_Xxx functions and must be released by peak_Camera_Close.
The camera handle is required in every function which controls a camera of its features.

The value for an invalid camera handle is PEAK_INVALID_HANDLE.

◆ peak_camera_id

typedef uint64_t peak_camera_id

peak Camera ID

The camera id is a unique identifier for a camera.

The camera related functions which can be used without opening a camera require the camera id as identifier.
The id for a certain camera will not change over the session runtime as long as the camera is not re-connected. A re-connected camera will be assigned a new unique camera id on its re-appearance.
I.e. a once assigned camera id is considered as burnt and will not be reused for a later (re-)connected camera.

The value for an invalid camera id is PEAK_INVALID_CAMERA_ID.

Enumeration Type Documentation

◆ peak_camera_type

enum peak_camera_type

peak Camera types

The camera type defines the camera family and the bus interface / protocol.

Enumerator
PEAK_CAMERA_TYPE_INVALID	Invalid camera type. Use this value for the initialization of variables of type peak_camera_type.
PEAK_CAMERA_TYPE_UEYE_USB	uEye USB camera
PEAK_CAMERA_TYPE_UEYE_ETH	uEye Eth camera
PEAK_CAMERA_TYPE_UEYE_PLUS_U3V	uEye+ USB3 Vision camera

◆ peak_CameraList_Get()

peak_status peak_CameraList_Get	(	peak_camera_descriptor *	cameraList,
		size_t *	cameraCount
	)

Query the current camera list.

Provides the current list of detected cameras.

This function implements the Two Staged Data Query principle.

Parameters

[out]	cameraList	Pointer to a user allocated array buffer to receive the camera list. If this parameter is NULL, `cameraCount` will contain the current number of cameras. The needed size of `cameraList` in bytes is `cameraCount` x sizeof(peak_camera_descriptor).
[in,out]	cameraCount	`cameraList` equal NULL: out: minimal number of cameras `cameraList` must be large enough to hold `cameraList` unequal NULL: in: number of cameras `cameraList` can hold out: number of cameras filled by the function

Returns: PEAK_STATUS_SUCCESS Operation was successful; no error occurred.; PEAK_STATUS_BUFFER_TOO_SMALL cameraList is not NULL and the value of *cameraCount is too small to receive the expected amount of data.; PEAK_STATUS_INVALID_PARAMETER cameraCount is an invalid pointer.; PEAK_STATUS_NOT_INITIALIZED The library is not initialized.; PEAK_STATUS_ERROR An unexpected internal error occurred.

Note: Consider that the camera list might change between the size query call and the list query call. This may be the case if peak_CameraList_Update is called and cameras have been attached or detached in the time between the two function calls. To eliminate this issue you may want to use an array for cameraList which is large enough to hold all possibly connected cameras and to spare the size query call.

◆ peak_CameraList_Update()

peak_status peak_CameraList_Update ( size_t * cameraCount )

Update the camera list.

Initiates a camera discovery and an update of the camera list.

This function is required to be called to create or update the camera list. The camera list does not change unless this function is called again.

Parameters

[out] cameraCount The number of connected cameras. NULL if not required.

Returns: PEAK_STATUS_SUCCESS Operation was successful; no error occurred.; PEAK_STATUS_NOT_INITIALIZED The library is not initialized.; PEAK_STATUS_ERROR An unexpected internal error occurred.

Note: Depending on the installed transport layers the camera list may take some hundred milliseconds. This is because the discovery of cameras via so called connectionless network protocols like ethernet requires a timeout controlled procedure.
