Member Function Documentation

virtual void opentl::input::VideoFile::captureNext

(

)

[virtual]

capture next image

Reimplemented from opentl::input::ImageSensor.

virtual void opentl::input::VideoFile::captureStart

(

)

[virtual]

start capture process

Reimplemented from opentl::input::ImageSensor.

virtual void opentl::input::VideoFile::captureStop

(

)

[virtual]

stop capture process

Reimplemented from opentl::input::ImageSensor.

virtual void opentl::input::VideoFile::close

(

)

[virtual]

close video file

Reimplemented from opentl::input::AbstractSensor.

double opentl::input::VideoFile::getSpeed

(

)

get speed factor the frame rate of a video is multiplied with. The higher the speed, the faster the video is running. A value of 1.0 means realtime.

Returns:

speed factor

virtual const opentl::core::cvdata::Image& opentl::input::VideoFile::image

(

)

[virtual]

get image data from last captured image

Returns:

image data

Reimplemented from opentl::input::ImageSensor.

virtual void opentl::input::VideoFile::init

(

)

[virtual]

initialize video capturing process

Reimplemented from opentl::input::AbstractSensor.

bool opentl::input::VideoFile::isFinished

(

)

const

check if end video file has been reached

Returns:

true if video is finished else false

virtual void opentl::input::VideoFile::open

(

)

[virtual]

open video stream from given file (constructor)

Reimplemented from opentl::input::AbstractSensor.

void opentl::input::VideoFile::setSpeed

(

double

factor

)

set speed factor the frame rate of a video is multiplied with. The higher the speed, the faster the video is running. A value of 1.0 means realtime.
