我正在使用新的Apple Vision API的VNImageTranslationAlignmentObservation来返回CGAffineTransform。这个想法是你传递两个可以合并在一起的图像并返回CGAffineTransform,这样你就可以这样做。我已经设法让代码工作,以便我得到一个CGAffineTransform返回,但经过大量阅读我不知道如何我可以合并两个图像与信息。
我的代码在这里:
import UIKit
import Vision
class ImageTranslation {
let referenceImage: CGImage!
let floatingImage: CGImage!
let imageTranslationRequest: VNTranslationalImageRegistrationRequest!
init(referenceImage: CGImage, floatingImage: CGImage) {
self.referenceImage = referenceImage
self.floatingImage = floatingImage
self.imageTranslationRequest = VNTranslationalImageRegistrationRequest(targetedCGImage: floatingImage, completionHandler: nil)
}
func handleImageTranslationRequest() -> UIImage {
var alignmentTransform: CGAffineTransform!
let vnImage = VNSequenceRequestHandler()
try? vnImage.perform([imageTranslationRequest], on: referenceImage)
if let results = imageTranslationRequest.results as? [VNImageTranslationAlignmentObservation] {
print("Image Transformations found \(results.count)")
results.forEach { result in
alignmentTransform = result.alignmentTransform
print(alignmentTransform)
}
}
return applyTransformation(alignmentTransform)
}
private func applyTransformation(_ transform: CGAffineTransform) -> UIImage {
let image = UIImage(cgImage: referenceImage)
return image
}
}
我得到的打印转换就像CGAffineTransform(a: 1.0, b: 0.0, c: 0.0, d: 1.0, tx: 672.0, ty: 894.0)
如何将这两张传入的图片应用于这两张?
