and how to solve themQ Parallax Map effect is not good how to do?A:1, it is possible that you left the camera in reverse.2, the result of calibration is not good, parallax map certainly will not be better, and then re-calibration3, calibration no problem, but after calibration you two camera position changesDistance information 3d Point cloud is based on the disparity map, the disparity map is not allowed to get the distance information is certainly not allowed, but I think most of the disparit

First of all, thank De Lihui Teacher Translation finishing of the "Opencv-python Chinese course", this document is really good, for OpenCV beginners, help is very large, can let beginners quick start. Recommend two OPENCV learning sites: (1) http://docs.opencv.org/2.4/index.html This site can query the use of

1,Learning Method: Http://www.opencv.org.cn/forum.php? MoD = viewthread tid = 7055 extra = page = 1 First of all, let's talk about how to learn opencv. I remember that when I first went to the lab, my brother showed me opencv. At that time, my academic foundation was very poor and my programming skills were very good. So I felt helpless when I learned

the array frame because the video Analysis Module Videocapture component has been able to obtain the resolution and bit depth information of the USB camera. While the Cvtcolor method automatically allocates memory for the edges array, the data information for the edges array is the same as the input array, and Cv_bgr2gray determines the color space type of the output image. In the above loop, edges's memory is only allocated once, and if the resolution of the input image changes, the memory is

, don't forget that we're talking about a computationally large graph processing algorithm, so unless it's a last resort, We should not copy large images, because this will reduce the speed of the program 4--in order to solve this problem, OPENCV uses the---Reference counting mechanism, the idea is to let each mat object has its own information header, but share a matrix. Implemented by having the matrix pointer point to the same address. The copy con

One, (1) Shallow copy:Mat B;B = image//First wayMat C (image); The second wayThese two methods are called shallow copy, because they have different matrix headers, but they share memory space, that is, point to a matrix. When the image matrix changes, the two are correlated and will change.(2) deep copyMat B,c;B = Image.clone (); The first wayImage.copyto (C); The second wayDeep copy is a real copy of a new image matrix, at which time the Image,b,c th

the two cvcreatedata () functions are responsible only for the memory allocation of the data. Sometimes, only the function Cvcreatematheader () is required because storage space has been allocated for other reasons, or because storage space is not yet ready to be allocated. The third method uses the function Cvclonemat (cvmat*), which creates a new matrix based on an existing matrix. When the matrix is no longer needed, you can call the function Cvreleasemat (cvmat*) to release it. The above fu

Original works, reproduced please indicate the source In order to enhance the force lattice, decided to learn OpenCV, think if you can face recognition, fixed-point landing, let the plane fly with their own. It's a little bit exciting to think about it. This is just thinking, can learn not to know yet.

Or a program with real-time requirements recently put me on fire. To speed up code running, I also learned something new. Because vector is used in my code, I searched for it on the Internet. Some people say that the vector is slow, and some people say that the sort sorting speed in STL is something that I can't do for ordinary people. Some people say that we need less resize, this re-allocation of memory is very time-consuming, and some people say they should use swap to completely delete unwan

Many artificial intelligence tasks can be solved by designing the right set of features to extract for that task, then pro Viding these features to a simple machine learning algorithm. For example,a useful feature for speaker identification from sound is the pitch. One solution to this problem are to use machine
