我做了很少的AR图像跟踪应用程序和AR World跟踪应用程序。
AR图像跟踪可用于识别从相机捕获的物理地图上的图像。
有什么方法可以使AR Image Tracking识别基本上是SCNPlane材料的虚拟“图像”?
如果有人可以给我一些指导或建议,我们将不胜感激。
(注意:,对于该项目,我在ARWorldTrackingConfiguration上使用检测图像)

我认为可能是的,可以通过将内容图像(要在地图中检测到的图像)添加到Assets.xcassets中来实现。然后使用此代码检测虚拟图像,如下所示:
///将您的图片名称放入(withName:“ namehere”)
lazy var mapNode: SCNNode = {
let node = scene.rootNode.childNode(withName: "map", recursively: false)
return node
}()
// Now When detecting Images
extension ViewController: ARSCNViewDelegate {
func renderer(_ renderer: SCNSceneRenderer, didAdd node: SCNNode, for anchor: ARAnchor) {
DispatchQueue.main.async {
guard let imageAnchor = anchor as? ARImageAnchor,
let imageName = imageAnchor.referenceImage.name else { return }
// TODO: Comment out code
// let planeNode = self.getPlaneNode(withReferenceImage: imageAnchor.referenceImage)
// planeNode.opacity = 0.0
// planeNode.eulerAngles.x = -.pi / 2
// planeNode.runAction(self.fadeAction)
// node.addChildNode(planeNode)
// TODO: Overlay 3D Object
let overlayNode = self.getNode(withImageName: imageName)
overlayNode.opacity = 0
overlayNode.position.y = 0.2
overlayNode.runAction(self.fadeAndSpinAction)
node.addChildNode(overlayNode)
self.label.text = "Image detected: \"\(imageName)\""
}
}
func getPlaneNode(withReferenceImage image: ARReferenceImage) -> SCNNode {
let plane = SCNPlane(width: image.physicalSize.width,
height: image.physicalSize.height)
let node = SCNNode(geometry: plane)
return node
}
func getNode(withImageName name: String) -> SCNNode {
var node = SCNNode()
switch name {
case "map":
node = mapNode
default:
break
}
return node
}
}
