async2v.components.opencv.projector module¶

Summary¶

Classes:

`ProjectorDriver2d`	Draw overlays into the real world with a projector
`ProjectorDriver2dConfiguration`	Configuration for the `ProjectorDriver2d` component
`ProjectorDriver2dConfigurator`	Configurator for the `ProjectorDriver2d` component

Reference¶

class ProjectorDriver2dConfiguration(debug=False)¶

Bases: object

Configuration for the ProjectorDriver2d component

debug = False¶

Type:	bool

Emit debug frames during projector calibration

class ProjectorDriver2dConfigurator¶

Bases: async2v.cli.Configurator

Configurator for the ProjectorDriver2d component

static config_from_args(args)¶: Get configuration from argparse output

class ProjectorDriver2d(source, overlay, projector='projector', config=ProjectorDriver2dConfiguration(debug=False))¶

Bases: async2v.components.base.EventDrivenComponent, async2v.components.base.ContainerMixin

Draw overlays into the real world with a projector

This component automatically calibrates a projector that projects into the field of view of a camera. Overlays can then be drawn in coordinates of the camera image. Calibration is performed automatically on start. It can also be triggered later by sending an arbitrary event to the key stored in RESET_CALIBRATION_TRIGGER.

Parameters:	source (`str`) – Key of the video stream input. Needs to provide events with `Frame` payload. overlay (`str`) – Key of the overlay input. Needs to provide events with `Frame` payload. projector (`str`) – Key of projector output. `Frame` events are pushed to this output. config (`ProjectorDriver2dConfiguration`) – Can be generated via `ProjectorDriver2dConfigurator`

RESET_CALIBRATION_TRIGGER = 'async2v.projector.trigger.reset_calibration'¶: Event key for reset command input. Events on this key trigger a new projector calibration.

static configurator()¶

Convenience method to create a matching configurator

Return type:	`ProjectorDriver2dConfigurator`
