ABBYY Cloud OCR SDK的名片識別接口

因爲公司最近的軟件項目設備選型是windows 8平板電腦，開發Windows app store上的Metro應用，該應用要實現客戶名片識別的功能，即便用平板電腦上的攝像頭給客戶的名片拍照，應用能即時可識別該客戶名片上的信息，並自動輸入應用中，網上看了一大堆的資料，國內的開發商提供的接口服務費都過高了，動輒就要幾十萬。國外有個免費的，這個就是ABBYY Cloud OCR SDK，但ABBYY Cloud OCR SDK的名片識別接口沒有js的接口。它只提供了C#語言和iPhone的例子。這樣須要在服務器上用C#作一個轉換的方法。由平板向服務器發送客戶名片的照片，服務器再向ABBYY Cloud OCR SDK的名片識別接口發出識別請求，服務器接收到識別結果再向平板返回結果了。

 

C#的請求識別代碼：

public void ProcessFile(string sourceFilePath, string outputFileBase, ProcessingSettings settings)
        {
            Console.WriteLine("Uploading to www.fenhon.com ...");
            Task task = restClient.ProcessImage(sourceFilePath, settings);

            TaskId taskId = task.Id;

            while (true)
            {
                task = restClient.GetTaskStatus(taskId);
                if (!Task.IsTaskActive(task.Status))
                    break;

                Console.WriteLine(String.Format("Task status: {0}", task.Status));
                System.Threading.Thread.Sleep(1000);
            }

            if (task.Status == TaskStatus.Completed)
            {
                Console.WriteLine("Processing completed.");
                for (int i = 0; i < settings.OutputFormats.Count; i++)
                {
                    var outputFormat = settings.OutputFormats[i];
                    string ext = settings.GetOutputFileExt(outputFormat);
                    restClient.DownloadUrl(task.DownloadUrls[i], outputFileBase + ext);
                }
                Console.WriteLine("Download completed.");
            }
            else if (task.Status == TaskStatus.NotEnoughCredits)
            {
                Console.WriteLine("Not enough credits to process the file. Please add more pages to your application balance.");
            }
            else
            {
                Console.WriteLine("Error while processing the task");
            }
        }

一、 ocrsdk名片識別的接口：[POST] http(s)://cloud.ocrsdk.com/processBusinessCard

processBusinessCard Method
The method allows you to recognize a business card on an image. The method loads the image, creates a processing task for the image with the specified parameters, and passes the task for processing.

[POST] http(s)://cloud.ocrsdk.com/processBusinessCard
The image file is transmitted in the request body.
