为什么 Google Cloud Vision API 的 Node Client 不考虑纵横比

如何解决为什么 Google Cloud Vision API 的 Node Client 不考虑纵横比

我正在尝试将 Node Client 用于 Google Cloud Vision API。我设法使用以下方法获取远程图像的裁剪提示：

const [result] = await clientVision.cropHints(`gs://mybucket/${image.name}`,{imageContext : {cropHintsParams : {aspectRatios : [1]}}});

但是没有考虑纵横比。我可以将 aspectRatios 的值更改为 1 或 4 或浮点数 1.33333，我的顶点获得相同的坐标。默认纵横比好像是 1.77。

知道为什么吗？

解决方法

我最终使用了其余的 api：

function getHints(aspect,path) {

return new Promise((resolve,reject) => {

    axios.post('https://vision.googleapis.com/v1/images:annotate?key=xxxxxxxxxxxxxxxxxx',{
        "requests": [
            {
                "image": {
                    "source": {
                        "gcsImageUri": `gs://myproject/${path}`
                    }
                },"features": [
                    {
                        "type": "CROP_HINTS"
                    }
                ],"imageContext": {
                    "cropHintsParams": {
                        "aspectRatios": [
                            aspect
                        ]
                    }
                }
            }
        ]
    }).then((response) => {

        console.info(response.data['responses'])

        var vertices = response.data['responses'][0].cropHintsAnnotation.cropHints[0].boundingPoly.vertices;


        if (vertices[0].x == undefined) {
            vertices[0].x = 0
        }
        if (vertices[0].y == undefined) {
            vertices[0].y = 0
        }

        if (vertices[1].x == undefined) {
            vertices[1].x = 0
        }
        if (vertices[1].y == undefined) {
            vertices[1].y = 0
        }

        if (vertices[2].x == undefined) {
            vertices[2].x = 0
        }
        if (vertices[2].y == undefined) {
            vertices[2].y = 0
        }
        if (vertices[3].x == undefined) {
            vertices[3].x = 0
        }
        if (vertices[3].y == undefined) {
            vertices[3].y = 0
        }

        resolve(vertices)

    }).catch(error => {
        console.log(error.response)
    });


})

我是这么用的：

var hints = await getHints(1.777777778,path)
