I’m trying to stitch two images together with the stitcher class in ofxOpenCv and also using ofxCv.
I load in 2 images and convert them to OpenCV data with toCv() in ofxCv. I then push the Mat into a vector and then attempt to stitch.
The issue is that I get a SIGABRT error on the line below:
cv::Stitcher::Status status = stitcher.stitch(imgs, pano);
The error:
OpenCV Error: Assertion failed (ssize.area() > 0) in resize, file /Users/danielrosser/Documents/openFrameworks/scripts/apothecary/build/opencv/modules/imgproc/src/imgwarp.cpp, line 1834
libc++abi.dylib: terminating with uncaught exception of type cv::Exception: /Users/danielrosser/Documents/openFrameworks/scripts/apothecary/build/opencv/modules/imgproc/src/imgwarp.cpp:1834: error: (-215) ssize.area() > 0 in function resize
Not too sure what I’m doing wrong with the implementation maybe need to do something else with the second argument in the line I get the error on.
Any help would be great!
See below for the code.
void ofApp::setup(){
image1.load("i_1.JPG");
image2.load("i_2.JPG");
image1.setImageType(OF_IMAGE_COLOR);
image2.setImageType(OF_IMAGE_COLOR);
Mat mImage1 = toCv(image1);
Mat mImage2 = toCv(image2);
imgs.resize(2);
imgs.push_back(mImage1);
imgs.push_back(mImage2);
}
//--------------------------------------------------------------
void ofApp::update(){
ofSetWindowTitle(ofToString(ofGetFrameRate()));
}
//--------------------------------------------------------------
void ofApp::draw(){
ofSetColor(255);
bool try_use_gpu = false; //true; //
cv::Stitcher stitcher = cv::Stitcher::createDefault(try_use_gpu);
cv::Stitcher::Status status = stitcher.stitch(imgs, pano);
if (status != cv::Stitcher::OK){
cout << "Can't stitch images, error code = " << status << endl;
}
for(int i=0;i< 2;i++){
drawMat(imgs[i], i*500, 0);
}
ofSetColor(255);
drawMat(pano, 0, 400);
}
Relevant h file stuff:
#include "../../../addons/ofxOpenCv/libs/opencv/include/opencv2/stitching/stitcher.hpp"
vector<cv::Mat> imgs;
cv::Mat pano;
ofImage image1, image2;
vector<ofImage> img2;
