opencv 編譯報錯解決辦法

將 NO換成NO_EXPOSURE_COMPENSATOR

IplImage 找不到 導入頭文件

#import "opencv2/imgproc/imgproc_c.h"

CV_RGB2BGR 找不到 導入頭文件

#import <opencv2/imgproc/types_c.h>

cvCvtColor 找不到 導入頭文件

#import <opencv2/imgproc/imgproc_c.h>

ocimageView轉opencv代碼如下

• (IplImage )convertToIplImage:(UIImage)image
  {
  CGImageRef imageRef = image.CGImage;
  CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB();
  IplImage *iplImage = cvCreateImage(cvSize(image.size.width, image.size.height), IPL_DEPTH_8U, 4);
  CGContextRef contextRef = CGBitmapContextCreate(iplImage->imageData, iplImage->width, iplImage->height, iplImage->depth, iplImage->widthStep, colorSpace, kCGImageAlphaPremultipliedLast | kCGBitmapByteOrderDefault);
  CGContextDrawImage(contextRef, CGRectMake(0, 0, image.size.width, image.size.height), imageRef);
  CGContextRelease(contextRef);
  CGColorSpaceRelease(colorSpace);
  IplImage *ret = cvCreateImage(cvGetSize(iplImage), IPL_DEPTH_8U, 3);
  cvCvtColor(iplImage, ret, CV_RGB2BGR);
  cvReleaseImage(&iplImage);
  return ret;
  }

/// IplImage類型轉換為UIImage類型

• (UIImage *)convertToUIImage:(IplImage *)image
  {
  cvCvtColor(image, image, CV_BGR2RGB);
  CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB();
  NSData *data = [NSData dataWithBytes:image->imageData length:image->imageSize];
  CGDataProviderRef provider = CGDataProviderCreateWithCFData((CFDataRef)data);
  CGImageRef imageRef = CGImageCreate(image->width, image->height, image->depth, image->depth * image->nChannels, image->widthStep, colorSpace, kCGImageAlphaNone | kCGBitmapByteOrderDefault, provider, NULL, false, kCGRenderingIntentDefault);
  UIImage *ret = [UIImage imageWithCGImage:imageRef];
  CGImageRelease(imageRef);
  CGDataProviderRelease(provider);
  CGColorSpaceRelease(colorSpace);
  return ret;
  }

• (cv::Mat)convertToMatImage:(UIImage *)image{

  // 將UIImage 轉成 cv::Mat
  cv::Mat cvFaceImage;
  UIImageToMat(image, cvFaceImage);

  return cvFaceImage;
  }

• (UIImage *)convertMatToUIImage:(cv::Mat)matimage{

  //繪制出關鍵點的image
  UIImage *result = MatToUIImage(matimage);
  matimage.release();

  return result;
  }
