1). 集成openCV具体看这里
2). 添加src、thirdparty、include、model (model为蓝色)
并保证
copy bundle resource里引入了蓝色文件夹model
Complie Sources添加了src和util的文件夹内cpp文件
3). Header Search Path添加$(SRCROOT)/EasyPR_iOS/include
4). 尝试#include "easypr.h"发现报错
原因应该是名字和iOSMacTypes.h的冲突了
处理方法:报错的全部加cv::前缀。
5). 尝试运行,发现报错,原因是路径的问题
解决方法:
解决方法参考了https://github.com/zhoushiwei/EasyPR-iOS:
根据include/esaypr/config.h里的变量名,创建全局变量,并修改源码。
新建cpp文件:
SGGlobalEasyPRPath.hpp:
#ifndef SGGlobalEasyPRPath_hpp
#define SGGlobalEasyPRPath_hpp
#include <stdio.h>
#include <string>
class SGGlobalEasyPRPath {
public:
static std::string kDefaultSvmPath;
static std::string kLBPSvmPath;
static std::string kHistSvmPath;
static std::string kDefaultAnnPath;
static std::string kChineseAnnPath;
static std::string kGrayAnnPath;
static std::string kChineseMappingPath;
SGGlobalEasyPRPath()=default;
private:
};
#endif /* SGGlobalEasyPRPath_hpp */
SGGlobalEasyPRPath.hpp:
#include "SGGlobalEasyPRPath.hpp"
std::string SGGlobalEasyPRPath::kDefaultSvmPath;
std::string SGGlobalEasyPRPath::kLBPSvmPath;
std::string SGGlobalEasyPRPath::kHistSvmPath;
std::string SGGlobalEasyPRPath::kDefaultAnnPath;
std::string SGGlobalEasyPRPath::kChineseAnnPath;
std::string SGGlobalEasyPRPath::kGrayAnnPath;
std::string SGGlobalEasyPRPath::kChineseMappingPath;
使用之前赋给变量值,比如写到AppDelegate.mm里面:
#import "AppDelegate.h"
#include "SGGlobalEasyPRPath.hpp"
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
NSString* bundlePath=[[NSBundle mainBundle] bundlePath];
SGGlobalEasyPRPath::kDefaultSvmPath = [[NSString stringWithFormat:@"%@/model/svm_hist.xml",bundlePath] UTF8String];;
SGGlobalEasyPRPath::kLBPSvmPath = [[NSString stringWithFormat:@"%@/model/svm_lbp.xml",bundlePath] UTF8String];;
SGGlobalEasyPRPath::kHistSvmPath = [[NSString stringWithFormat:@"%@/model/svm_hist.xml",bundlePath] UTF8String];;
SGGlobalEasyPRPath::kDefaultAnnPath = [[NSString stringWithFormat:@"%@/model/ann.xml",bundlePath] UTF8String];;
SGGlobalEasyPRPath::kChineseAnnPath = [[NSString stringWithFormat:@"%@/model/ann_chinese.xml",bundlePath] UTF8String];;
SGGlobalEasyPRPath::kGrayAnnPath = [[NSString stringWithFormat:@"%@/model/annCh.xml",bundlePath] UTF8String];;
SGGlobalEasyPRPath::kChineseMappingPath = [[NSString stringWithFormat:@"%@/model/province_mapping",bundlePath] UTF8String];;
std::cout<<"SGGlobalEasyPRPath::mainBundle():"<< SGGlobalEasyPRPath::kChineseAnnPath <<std::endl;
return YES;
}
@end
然后修改源代码,将用到路径的地方 #include "SGGlobalEasyPRPath.hpp"并添加前缀SGGlobalEasyPRPath::
如:kChineseMappingPath改为SGGlobalEasyPRPath::kChineseMappingPath。
注意:引用SGGlobalEasyPRPath.hpp的.m文件,后缀改为.mm
5). 跑下测试效果
#import "ViewController.h"
#import <opencv2/opencv.hpp>
#include "easypr.h"
using namespace cv;
using namespace easypr;
@interface ViewController ()
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
[self myFunction];
}
- (void)myFunction{
cv::Mat cvImage;
cv::Mat RGB;
CPlateRecognize pr;
NSString *path = [[NSBundle mainBundle] pathForResource:@"test" ofType:@"jpg"];
Mat img = imread([path UTF8String]);
if (img.empty()) {
return;
}
cvtColor(img, RGB, COLOR_BGRA2RGB);
vector<CPlate> plateVec;
int result = pr.plateRecognize(RGB, plateVec);
NSLog(@"result %@",@(result));
if (result != 0) cout << "result:" << result << endl;
if(plateVec.size()==0){
}else {
string name=plateVec[0].getPlateStr();
NSString *resultMessage = [NSString stringWithCString:plateVec[0].getPlateStr().c_str()
encoding:NSUTF8StringEncoding];
NSLog(@"%@",resultMessage);
}
}
@end
