I am working on business card profile information using ar reference image. When reference detects it will show company ceo details, address, photo and team members information, etc. Initially image detected it plane will move to right using runAction amintion.
My question is detected ar refrence, plane position was stable and its moving here and there. How to fit plane position with ar reference image.
Here is the screenshot my result:[![enter image description here][1]][1]
Here is the code i used:
var weboverlayview: CALayer?
var loadWeb: UIWebView?
override func viewDidLoad() {
super.viewDidLoad()
// Set the view's delegate
sceneView.delegate = self
// Show statistics such as fps and timing information
sceneView.showsStatistics = true
sceneView.autoenablesDefaultLighting = true
let ARScene = SCNScene()
sceneView.scene = ARScene
}
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
// Create a session configuration
let configuration = ARWorldTrackingConfiguration()
configuration.planeDetection = [.vertical, .horizontal]
configuration.detectionImages = ARReferenceImage.referenceImages(inGroupNamed: "AR Resources", bundle: nil)
// Run the view's session
sceneView.session.run(configuration)
}
override func viewWillDisappear(_ animated: Bool) {
super.viewWillDisappear(animated)
// Pause the view's session
sceneView.session.pause()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Release any cached data, images, etc that aren't in use.

Solved
I had a similar problem and it was because a mistake setting the size of Reference Images.
If you're manually importing them to your "AR Resources Group", then you need to be sure to set "meters" or "centimetres" when typing the width and height on the right panel.
If you're loading those images from a server and than making them Reference Images, remember the default metric ARKit uses is "meters". In this case, if you set the width as 20.0, ARKit will consider 20 meters instead of 20 centimetres, bringing you a very inaccurate behaviour when tracking the image plane.
Hope it helps.
The first thing you need to consider is whether you want to use ARWorldTrackingConfiguration or ARImageTrackingConfiguration (IOS12).
If you use ARImageTrackingConfiguration, you cant make use of PlaneDetection, as this is an Image Only tracking configuration:
which lets you anchor virtual content to known images only when those
images are in view of the camera. World tracking with image detection
lets you use known images to add virtual content to the 3D world, and
continues to track the position of that content in world space even
after the image is no longer in view.
This would be your best bet, if you want your content to stay anchored to the image at all times (when in view of the camera) since:
it tracks their movement with six degrees of freedom (6DOF):
specifically, the three rotation axes (roll, pitch, and yaw), and
three translation axes (movement in x, y, and z).
On the other hand if you want to detect ARPlaneAnchors, as well as ARImageAnchors, but aren't bothered that any content associated with your ARImageAnchor won't track constantly then you should use ARWorldTrackingConfiguration.
As @Trinca also said you need to ensure that the measurements you provide for your image are as accurate as possible, as ARKit uses these to return the physicalSize and physicalWidth of your image which will allow your virtual content to placed more accurately (e.g if you specify a larger size than the actual size of your image in real life, your not going to be able to align your virtual content accurately).
Lets say for example we have a business card that is 5*3cm:
We make sure that our dimensions are accurately set in the ARReferenceImage Settings box:
We can then check to see if our imageTarget is detected like so:
func renderer(_ renderer: SCNSceneRenderer, didAdd node: SCNNode, for anchor: ARAnchor) {
//1. Check We Have Detected An ARImageAnchor & Check It's The One We Want
guard let validImageAnchor = anchor as? ARImageAnchor,
let targetName = validImageAnchor.referenceImage.name, targetName == "TargetCard" else { return}
//2. Check To See The Detected Size Of Our Business Card (Should By 5cm*3cm)
let businessCardWidth = validImageAnchor.referenceImage.physicalSize.width
let businessCardHeight = validImageAnchor.referenceImage.physicalSize.height
print(
"""
We Have Detected Business Card With Name \(targetName)
\(targetName)'s Width Is \(businessCardWidth)
\(targetName)'s Height Is \(businessCardHeight)
""")
}
Having checked that our detected size is accurate we can then place whatever content we like in relation to this.
Rather than doing everything programatically, an easier way to achieve the results you are looking for is to create an SCNScene.
I first created an SCNPlane matching the known size of our Business Card then I created my content exactly to the right, thus removing any need for calculations etc:
I then set the isHidden variable for my Target to true as we dont want to see that!
By providing each node an name in the SCNScene we can then load the website for example as the diffuse.contents of the WebsiteNode etc.
extension ViewController: ARSCNViewDelegate{
func renderer(_ renderer: SCNSceneRenderer, didAdd node: SCNNode, for anchor: ARAnchor) {
//1. Check We Have Detected An ARImageAnchor & Check It's The One We Want
guard let validImageAnchor = anchor as? ARImageAnchor,
let targetName = validImageAnchor.referenceImage.name, targetName == "TargetCard" else { return}
//2. Check To See The Detected Size Of Our Business Card (Should By 5cm*3cm)
let businessCardWidth = validImageAnchor.referenceImage.physicalSize.width
let businessCardHeight = validImageAnchor.referenceImage.physicalSize.height
print(
"""
We Have Detected Business Card With Name \(targetName)
\(targetName)'s Width Is \(businessCardWidth)
\(targetName)'s Height Is \(businessCardHeight)
""")
//3. Get Our BusinessCard Info
guard let businessCardInfo = SCNScene(named: "art.scnassets/Overlay.scn") else { return }
let model = businessCardInfo.rootNode
//4. Rotate The Model So It Matches Our ARImageAnchor
model.transform = SCNMatrix4MakeRotation(-Float.pi / 2, 1, 0, 0)
//5. We Have Already Positioned Our Content In The SCNScene So Position It At SCNVector3Zero
model.position = SCNVector3Zero
//6. Add It To The Node
node.addChildNode(model)
}
}
Which yields something like so:
An awful (and not real business card), and a terrible UI Design, but hopefully it will point you in the right direction...
