HAL Device API

class Metavision::Device

Device abstraction.

Public Functions

template<typename FacilityType> inline FacilityType *get_facility(): Returns facility.

template<typename FacilityType> inline const FacilityType *get_facility() const: Returns facility.

Device(Device &&dev) = default

Move constructor.

Parameters: dev – Device from which this instance will be moved from

Device &operator=(Device &&dev) = default

Move operator.

Parameters: dev – Device from which a new instance will be moved from
Returns: A device moved from dev

enum Metavision::ConnectionType

Types of links.

Values:

enumerator MIPI_LINK

enumerator USB_LINK

enumerator NETWORK_LINK

enumerator PROPRIETARY_LINK

struct Metavision::PluginCameraDescription

Struct returned by the plugin with the camera information.

Subclassed by Metavision::CameraDescription

Public Members

std::string serial_: Serial number of the camera.

ConnectionType connection_: Type of connection used to communicate with the camera.

long system_id_: System Identification number.

struct Metavision::CameraDescription : public Metavision::PluginCameraDescription 

Struct to store camera information.

Public Functions

inline CameraDescription(const PluginCameraDescription &desc): Copy constructor from base class.

std::string get_full_serial() const: Returns a string identifying uniquely each camera in the form “integrator:plugin:serial”.

Public Members

std::string integrator_name_: Integrator’s name.

std::string plugin_name_: Plugin’s name.

using Metavision::DeviceDiscovery::SerialList = std::list<std::string>: Alias to list cameras’ serial numbers.

using Metavision::DeviceDiscovery::SystemList = std::list<CameraDescription>: Alias to list CameraDescription.

static SerialList Metavision::DeviceDiscovery::list(): Lists serial numbers of available sources, including remote cameras.

static SerialList Metavision::DeviceDiscovery::list_local(): Lists serial numbers of local available sources.

Note

A camera is considered local if we communicate directly with it.

static SerialList Metavision::DeviceDiscovery::list_remote(): Lists serial numbers of remote available sources.

Note

A camera is considered remote if it is part of another SoC and hence communication is indirect.

static SystemList Metavision::DeviceDiscovery::list_available_sources(): Lists available sources, including remote cameras.

static SystemList Metavision::DeviceDiscovery::list_available_sources_local(): Lists only local available sources.

Note

A source is considered local if we communicate directly with it.

static SystemList Metavision::DeviceDiscovery::list_available_sources_remote(): Lists only remote available sources.

Note

A source is considered remote if it is part of another SoC and hence communication is indirect.

static std::unique_ptr<Device> Metavision::DeviceDiscovery::open(const std::string &serial)

Builds a new Device.

Parameters: serial – Serial number of the camera to open. If it is an empty string, the first available camera will be opened
Returns: A new Device

static std::unique_ptr<Device> Metavision::DeviceDiscovery::open_raw_file(const std::string &raw_file)

Builds a new Device from file.

Parameters: raw_file – Path to the file to open
Returns: A new Device
