 ### 具体实现
 
-* 本实例完成AI文字识别的功能模块主要封装在CameraModel，源码参考:[CameraModel.ets](entry/src/main/ets/common/utils/Camera.ets) 。
+* 本实例完成AI文字识别的功能模块主要封装在CameraModel，源码参考:[Camera.ets](entry/src/main/ets/common/utils/Camera.ets) 。
     * 相机模块：在Camera中封装了相机初始化、相机释放。
     * 在Index页面通过点击事件触发相机拍摄，在获取到照片输出流后通过@hms.ai.ocr.textRecognition文字识别接口进行识别。
