选择图片及上传按钮代码如下:
private void button1_Click (object sender, EventArgs e) { try { richTextBox1.Text = ""; Openimgfile (); //调用文件打开对话框 this.button1.Text = "上传并提取中..."; pictureBox1.LoadAsync (textBox1.Text); GeneralBasicDemo (); 调用百度ai接口 } catch (Exception ex) { MessageBox.Show ("报错,原因:" + ex.Message, "错误", MessageBoxButtons.OK, MessageBoxIcon.Warning); } }
打开文件对话框过程代码:
//打开文件模块 public void Openimgfile () { try { OpenFileDialog dialog = new OpenFileDialog (); dialog.Filter = "图片(*.png;*.jpg;*.bmp;*.jpeg)|*.png;*.jpg;*.bmp;*.jpeg"; if (dialog.ShowDialog () == DialogResult.OK) { this.textBox1.Text = dialog.FileName; } } catch (Exception ex) { MessageBox.Show ("报错,原因:" + ex.Message, "错误", MessageBoxButtons.OK, MessageBoxIcon.Warning); } }
调用百度api接口 过程代码:
public void GeneralBasicDemo () { try { string Json; var APP_ID = "123456"; var API_KEY = "123456"; var SECRET_KEY = "123456"; var client = new Baidu.Aip.Ocr.Ocr (API_KEY, SECRET_KEY); client.Timeout = 60000; var image = File.ReadAllBytes (textBox1.Text); var result = client.GeneralBasic (image); Console.WriteLine (result); // 如果有可选参数 var options = new Dictionary<string, object> { { "language_type", "CHN_ENG" }, { "detect_direction", "true" }, { "detect_language", "true" }, { "probability", "true" } }; result = client.GeneralBasic (image, options); //Console.WriteLine(result); //richTextBox1.Text = result.ToString(); Json = result.ToString (); Json_get (Json); this.button1.Text = "选择图片并提取文字"; } catch (Exception ex) { MessageBox.Show ("报错,原因:" + ex.Message, "错误", MessageBoxButtons.OK, MessageBoxIcon.Warning); this.button1.Text = "选择图片并提取文字"; } }
百度返回的内容是json格式,需要从json中提取words关键字对应的值。
