同分辨率-Surf找图:findImgBySift(inputImage: Bitmap, targetImage: Bitmap, threshold: number): IntArray ✅ ​

参数:

  • ⭐any (Bitmap):大图
  • ⭐Bitmap (targetImage):小图
  • ⭐number (threshold):相似度

返回值:

  • 🟢Point[]:坐标数组
  • 🔴null

用法示例:

typescript
if (recordscreen.requestPermission(3)) {
    let bit = recordscreen.captureScreen(3, 0, 0, 0, -1)
    let target = converters.streamToBitmap(converters.assetsToStream("1.png"))
    console.log(images.findImgBySift(bit, target, 0.5))
    release.release(bit)
}
