【實(shí)例簡介】

比較簡陋的車輛牌照識別,起個拋磚引玉的作用

需要引用百度AipSdk,Newtonsoft.Json,自行在網(wǎng)上下載

API_KEY和SECRET_KEY 自行申請


【核心代碼】


richTextBox6.Text = "";
            var client = new Baidu.Aip.Ocr.Ocr(API_KEY, SECRET_KEY);
            filePath = FileDialogHelper.OpenImage();
            if (!string.IsNullOrEmpty(filePath))
            {
                
                pictureBox1.Image = Image.FromFile(filePath);
                var image = File.ReadAllBytes(filePath);
                pictureBox1.Refresh();

                // 如果有可選參數(shù)
                var options = new Dictionary<string, object>
                {
                {"multi_detect", "true"}
            };
                var result = client.LicensePlate(image, options);

                LicensePlate.RootObject rb = JsonConvert.DeserializeObject<LicensePlate.RootObject>(result.ToString());
                List<LicensePlate.Words_result> Result_info = rb.words_result;

                string value = "";
                richTextBox6.Text = "";

                List<LicensePlate.Vertexes_location> mylocation = new List<LicensePlate.Vertexes_location>();
                if (Result_info == null)
                {
                    richTextBox6.Text = "無法識別車輛牌照";
                    return;
                }
                value = "共識別到" Result_info.Count.ToString() "個車牌" "\r\n";
                for (int i = 0; i < Result_info.Count; i )
                {
                    mylocation = Result_info[i].vertexes_location;
                    DrawLine(mylocation[0].x, mylocation[0].y, mylocation[1].x, mylocation[1].y, pictureBox1);
                    pictureBox1.Refresh();
