Detailed Description

Interface to one Zivid camera.

See Settings and Settings2D for a list of settings that can be configured in the camera. Capture frames by calling capture.

Member Function Documentation

◆ capture() [1/2]

ZIVID_CORE_EXPORT Frame Zivid::Camera::capture ( const Settings settings)

Capture a single frame.

Parameters
settingsSettings to use for the capture
Returns
A frame containing a 3D point cloud and metadata

This method returns right after the acquisition of the images is complete, and the camera has stopped projecting patterns. Therefore, after this method has returned, the camera can be moved, or objects in the scene can be moved, or a capture from another camera with overlapping field of view can be triggered, without affecting the point cloud.

When this method returns, there is still remaining data to transfer from the camera to the PC, and the processing of the final point cloud is not completed. Transfer and processing of the point cloud will continue in the background. When you call a method on the returned Frame object that requires the capture to be finished, for example Frame::pointCloud(), that method will block until the processing is finished and the point cloud is available. If an exception occurs after the acquisition of images is complete (during transfer or processing of the capture), then that exception is instead thrown when you access the Frame object.

The capture function can be invoked back-to-back, for doing rapid back-to-back acquisition of multiple (2D or 3D) captures on the same camera. This is for example useful if you want to do one high-resolution 2D capture followed by a lower-resolution 3D capture. The acquisition of the next capture will begin quickly after acquisition of the previous capture completed, even when there is remaining transfer and processing for the first capture. This allows pipelining several 2D and/or 3D captures, by doing acquisition in parallel with data transfer and processing.

Note: There can be maximum of two in-progress uncompleted 3D captures simultaneously per Zivid camera. If you invoke capture when there are two uncompleted 3D captures in-progress, then the capture will not start until the first of the in-progress 3D captures has finished all transfer and processing. There is a similar limit of maximum two in-process 2D captures per camera.

capture can be called from multiple threads at the same time, for example by using std::async. Multiple capture commands on the same camera object from different threads will be queued and executed in order (first in, first out).

capture can also be called on multiple cameras simultaneously. However, if the cameras have overlapping field-of-view then you need to take consideration and sequence the capture calls to avoid the captures interfering with each other.

Note that all of these remarks apply for both 3D and 2D captures.

◆ capture() [2/2]

ZIVID_CORE_EXPORT Frame2D Zivid::Camera::capture ( const Settings2D settings2D)

Capture a single 2D frame.

Parameters
settings2DSettings2D to use for the capture
Returns
A frame containing a 2D image and metadata

This method returns right after the acquisition of the images is complete, and the camera has stopped projecting patterns. For more information, see the remarks section of capture(const Settings &settings) above. Those remarks apply for both 2D and 3D capture.

◆ closeAperture()

ZIVID_CORE_EXPORT void Zivid::Camera::closeAperture ( )

Close the camera's aperture.

The aperture will be opened again on the next call to capture.

◆ connect()

ZIVID_CORE_EXPORT Camera & Zivid::Camera::connect ( )

Connect to the camera.

◆ disconnect()

ZIVID_CORE_EXPORT void Zivid::Camera::disconnect ( )

Disconnect from the camera and free all resources associated with it.

◆ info()

ZIVID_CORE_EXPORT CameraInfo Zivid::Camera::info ( ) const

Get information about camera model, serial number etc.

◆ operator!=()

ZIVID_CORE_EXPORT bool Zivid::Camera::operator!= ( const Camera other) const

Check if two camera instances represent different devices.

◆ operator=() [1/2]

ZIVID_CORE_EXPORT Camera & Zivid::Camera::operator= ( Camera &&  other)
noexcept

Move assignment operator.

◆ operator=() [2/2]

ZIVID_CORE_EXPORT Camera & Zivid::Camera::operator= ( const Camera other)
noexcept

Copy assignment.

◆ operator==()

ZIVID_CORE_EXPORT bool Zivid::Camera::operator== ( const Camera other) const

Check if two camera instances represent the same device.

◆ state()

ZIVID_CORE_EXPORT CameraState Zivid::Camera::state ( ) const

Get the current camera state.

Returns
The current camera state

◆ toString()

ZIVID_CORE_EXPORT std::string Zivid::Camera::toString ( ) const

Get string representation of the camera info.

Returns
Camera info as string

◆ userData()

ZIVID_CORE_EXPORT std::vector< uint8_t > Zivid::Camera::userData ( ) const

Read user data from camera.

◆ writeUserData()

ZIVID_CORE_EXPORT void Zivid::Camera::writeUserData ( const std::vector< uint8_t > &  data)

Write user data to camera. The total number of writes supported depends on camera model and size of data.
