Class ImageTarget

Namespace
easyar
Assembly
EasyAR.Sense.dll

ImageTarget stellt ein target fur ein planar image dar, which can be tracked by `ImageTracker`_. Values in ImageTarget must first be filled by create... methods before they can be read. Then, after it is successfully loaded into `ImageTracker`_ through `ImageTracker.loadTarget`_, it can be detected and tracked by `ImageTracker`_.

Methoden

Clone() 

public ImageTarget Clone()

aspectRatio()

Aspect ratio of the image. 

public virtual float aspectRatio()

createFromImageFile(string, StorageType, string, string, string, float)

Erstellt from an image. If not needed, name, uid, and meta can be empty strings, and scale can use the default value 1. jpeg or png files are supported. 

public static Optional<ImageTarget> createFromImageFile(string path, StorageType storageType, string name, string uid, string meta, float scale)

Parameter

path
storageType
name
uid
meta
scale

createFromParameters(ImageTargetParameters)

Erstellt from parameters. 

public static Optional<ImageTarget> createFromParameters(ImageTargetParameters parameters)

Parameter

parameters

createFromTargetData(Buffer)

Erstellt from an etd data buffer. 

public static Optional<ImageTarget> createFromTargetData(Buffer buffer)

Parameter

buffer

createFromTargetFile(string, StorageType)

Erstellt from an etd file. 

public static Optional<ImageTarget> createFromTargetFile(string path, StorageType storageType)

Parameter

path
storageType

images()

Ruft ab the list of images stored in the target. This method is usually used to get the recognition images of a target returned from the cloud. 

public virtual List<Image> images()

meta()

Ruft ab the meta data set by setMetaData. Or, in a target returned by cloud recognition, gets the meta data set by the server. 

public override string meta()

name()

Ruft ab the target name. The name is used to distinguish targets in a json file. 

public override string name()

runtimeID()

Ruft ab the target id. target id is integer data created at runtime and is valid (non-zero) only after successful configuration. This id is non-zero and globally incremental. 

public override int runtimeID()

save(string)

Saves as an etd file. 

public virtual bool save(string path)

Parameter

path

scale()

Scale ratio of the image. Its value is the ratio between the physical width of the image and 1 meter. The default value is 1. 

public virtual float scale()

setMeta(string)

Legt fest meta data. This operation overrides the previous setting or data returned by the server. 

public override void setMeta(string data)

Parameter

data

setName(string)

Legt fest the target name. This operation overrides the previous setting or data returned by the server. 

public override void setName(string name)

Parameter

name

setScale(float)

Sets the scale ratio of the image. After it is set, it overrides the default value and the value set in the json file. Its value is the ratio between the physical width of the image and 1 meter. The default value is 1. This model scale also needs to be set separately in the rendering engine. 

public virtual bool setScale(float scale)

Parameter

scale

uid()

Ruft ab the target uid. The uid of ImageTarget is used in the cloud recognition algorithm. When cloud recognition is not integrated, you can set this uid in json configuration and use it in your own code as another way to distinguish targets. 

public override string uid()
