我正在使用Google的Vision API识别图像中的某些特征。当徽标出现在我的终端上时,我的徽标检测工作正常,但我无法将其显示在我的应用程序屏幕上。它不断打印“找不到徽标”-下面是我的代码:
//Get logo annotations
let logoAnnotations: JSON = logoResponses["logoAnnotations"]
let numLogos: Int = logoAnnotations.count
var logos: Array<String> = []
if numLogos > 0 {
var allResultsText:String = "Logos: "
for index in 0..<numLogos {
let logo = logoAnnotations[index]["logo"].stringValue
logos.append(logo)
}
for logo in logos {
if logos[logos.count - 1] != logo {
allResultsText += "\(logo), "
} else {
allResultsText += "\(logo)."
}
}
self.allResults.text = allResultsText
} else {
self.allResults.text = "No logos found"
}
}
这是我得到的JSON响应:
[
{
"boundingPoly": {
"vertices": [
{
"x": 210,
"y": 139
},
{
"x": 229,
"y": 139
},
{
"x": 229,
"y": 179
},
{
"x": 210,
"y": 179
}
]
},
"mid": "/m/04lg33",
"score": 0.18314756,
"description": "Ralph Lauren Corporation"
}
]
我如何访问徽标描述返回的值,本例为Ralph Lauren Corporation?
