2017-07-27 15:45:50 -0600 | commented question | Stereo camera calibration Thank you for the comment. Previously, i was working with only 14 image pair. Now i tried with 29. I see the epipolar lines matching nicely unlike above image. But RMS error = 1.56 average epipolar error = 2.6 . still remain higher. My square size is 20mm. The argument for variable S should in mm right. |

2017-07-26 13:26:02 -0600 | commented question | Point Grey camera interface with opencv I am using windows. There is no error after compiling the code but no windows is showing up and code is terminating instantly. Its working well with point grey software. I also interfaced with opencv C++ following their tutorial. Actually, i want to input video for camera calibration. |
2017-07-26 13:20:20 -0600 | commented answer | Point Grey camera interface with opencv Hi , Thanks for response. I was doing the way you mentioned before. But for the purpose of calibration using opencv, i want to choose video as an input. In the file "in_VID5.xml" is not working. I am wondering if there is way i can input point grey camera video as an input for the camera calibration. |

2017-03-30 00:52:57 -0600 | asked a question | 3D textured object model and object mesh. Hi I am thinking of model an outdoor environment (probable around 5000 sq.ft or even more). Later on,i want to estimate camera pose based on the image that i captured in the environment.(by matching my descriptors of the model with that in the image). I saw a tutorial in OpenCV - Real time pose estimation of a textured object. But is mentioned that the program only works for a planar objects. I am not sure which software should i need to use to make a 3D textured model from environment. Thinking of flying quad copter over a small area and converting it into model. Any thoughts about this or web links that can address this, would be greatly appreciated. Thanks |

2017-02-07 22:48:13 -0600 | asked a question | Converting CV::Mat to double * Hi, I am using C++ openCV-3.2.0 version. I am also using a library for line segment detection,which takes only .pgm image of data type double *. I used cv::Mat pgm_image; pgm_image = cv::imread("image.pgm"); double *I = pgm_image.ptr<double>(0); to read the image and to for getting pointer. And i tried parsing double * into the library that i am using. Is there any way around this? or Is there a way read .pgm file directly as double* ? |
