文字识别OCR

文字识别OCR目前在多个行业中得到了广泛应用比如金融行业的单据识别输入餐饮行业中的发票识别 交通领域的车票识别,企业中各种表单识别,以及日常工作生活中常用的身份证,驾驶证,护照识别等等。 OCR文字识别是目前常用的一种AI能力。

OCR识别SDK功能

  1. 方向检测
  • 0度
  • 90度
  • 180度
  • 270度
    detect_direction
  1. 图片旋转
  2. 文字识别

运行OCR识别例子

1. 文字方向检测:

  • 例子代码: OcrDetectionExample.java
  • 运行成功后,命令行应该看到下面的信息:
[INFO ] - Result image has been saved in: build/output/detect_result.png
[INFO ] - [
	class: "0", probability: 1.00000, bounds: [x=0.073, y=0.069, width=0.275, height=0.026]
	class: "0", probability: 1.00000, bounds: [x=0.652, y=0.158, width=0.222, height=0.040]
	class: "0", probability: 1.00000, bounds: [x=0.143, y=0.252, width=0.144, height=0.026]
	class: "0", probability: 1.00000, bounds: [x=0.628, y=0.328, width=0.168, height=0.026]
	class: "0", probability: 1.00000, bounds: [x=0.064, y=0.330, width=0.450, height=0.023]
]
  • 输出图片效果如下: detect_result

2. 文字方向检测帮助类(增加置信度信息显示,便于调试):

  • 例子代码: OcrDetectionHelperExample.java
  • 运行成功后,命令行应该看到下面的信息:
[INFO ] - Result image has been saved in: build/output/detect_result_helper.png
[INFO ] - [
	class: "0 :1.0", probability: 1.00000, bounds: [x=0.073, y=0.069, width=0.275, height=0.026]
	class: "0 :1.0", probability: 1.00000, bounds: [x=0.652, y=0.158, width=0.222, height=0.040]
	class: "0 :1.0", probability: 1.00000, bounds: [x=0.143, y=0.252, width=0.144, height=0.026]
	class: "0 :1.0", probability: 1.00000, bounds: [x=0.628, y=0.328, width=0.168, height=0.026]
	class: "0 :1.0", probability: 1.00000, bounds: [x=0.064, y=0.330, width=0.450, height=0.023]
]
  • 输出图片效果如下: detect_result_helper

3. 图片旋转:

每调用一次rotateImg方法会使图片逆时针旋转90度。

  • 例子代码: RotationExample.java
旋转前图片 旋转后图片

2. 文字识别:

再使用本方法前请调用上述方法使图片文字呈水平0度方向。

  • 例子代码: LightOcrRecognitionExample.java
  • 运行成功后,命令行应该看到下面的信息:
[INFO ] - Result image has been saved in: build/output/ocr_result.png
[INFO ] - [
	class: "你", probability: -1.0e+00, bounds: [x=0.319, y=0.164, width=0.050, height=0.057]
	class: "永远都", probability: -1.0e+00, bounds: [x=0.329, y=0.349, width=0.206, height=0.044]
	class: "无法叫醒一个", probability: -1.0e+00, bounds: [x=0.328, y=0.526, width=0.461, height=0.044]
	class: "装睡的人", probability: -1.0e+00, bounds: [x=0.330, y=0.708, width=0.294, height=0.043]
]
  • 输出图片效果如下: ocr_result
