Deals with Java programming, OpenCV also includes Android-compatible. C++ samples that you may. Do you ever wondered why do you have two eyes? In the most primitive sense, it is because only with both eyes we can have an idea of how far or near objects are. In some applications which need to recuperate 3D information it is made by using two cameras, this is called stereoscopy (). If you are trying to depict 3D information using a single camera, you only can have a poor approximation, in this case its needed a transformation called homography (), the last in order to try to model the perspective (or how far or near objects are). In most cases when we wanted to calibrate a single camera we try to remove the radial distortions produced by the lens of the camera (). Opencv offers you a tool to do this process, in most cases its needed a Chess board to help this process, you can check this:, in the spite of being more specific, the function cvFindChessboardCorners. I hope this could be useful to you, sorry for the english, no native speaker. I don't know if you already fixed your issue with the opnecv calibration but I will give you some hints anyway. First of all I suggest you to read the Zhang paper on calibration (). Opencv methods are based on Zhang's work so understanding it is a real priority. Calibrating a camera means determine the relation between camera 2D coordinate system (in pixel units, with the origin on top left corner of camera image) and the 3D coordinate systme of the external world (in metres, for example). When you place a known planar calibration object in front of the camera, the system should compute the homogeneous transformation between the knonw 3D object and the 2D one on image (that is the 'rvecs.get(i), tvecs.get(i)' you are talking about). Image coordinates are always in pixel and also the intrinsic calibration matrix is expressed in pixel. You cannot 'translate' from 2D image coordinates to 3D world coordinates but you can compute the proper transformation: it is composed by an intrinc calibration matrix and a roto-translation matrix. Please have a look also at this article Hope this helps! Chessboard Pdf Open Cv Java FileHello Oakmac! This is wonderful news! I've been looking for a fully functional javascript lib like this for a while now. I was resting my hopes on veltzer 'jschess' on github, but development stopped on that right before it was done. Your library supports movement of the pieces/drag drop etc. Etc., which is awesome! I am in the process of developing a website I've owned it for years, but plan to make something interesting out of it. Do you have a donation link anywhere? +1 Looking forward to testing this out in the coming days. Until now have only been able to find a variety of PGN viewers which didn't fit my needs. Only features not covered by your examples that I would be interested in are undo move and underpromotion. I guess the first of these would be trivially easy to implement as I see it's covered by the chess.js library. Would also like to donate to this. Many thanks for sharing. ![]() BorgQueen: I could write a tutorial for how to use this library, but maybe you should tell me exactly what you want to do? I'm guessing you want to be able to display pgn games that were played in your club? If that's so let me know here and I'll try to code up an example and tutorial. Let me know if you already have a webpage set up so I can figure out a way to add it to your html page (i can probably just give you an example change to the html file and tell you whatever else you need to set up). Hi Zenchess, Firstly, let me extend my appreciation for your offer of help. +10 for you for that:-) I would like to: a) put up a diagram in the website, alongside some text so that I can advertise cool positions, tactics or fixed opening/endgame positions that are going to be run at the club. B) put up a game that viewers can click through to see a 'showcase game' encountered at the club, or perhaps an endgame demonstration that can also be clicked through so users can see the moves. I have ok knowledge in HTML, MySQL and PHP, limited experience with CSS and almost no exposure to JavaScript. Hi BlauePeter, I'm a JS novice myself, but having alot of fun and learning heaps by messing around with this ChessBoard JS. Barcelona fc training drills. First I notice you are missing the jQuery library, which you should download and link to your html file. Secondly you do not need to include both the chessboard-0.3.0.min.js and chessboard-0.3.0.js files. They contain the same functionality, the min version is intended for production whereas the other is recommended for development as I understand it. All the best. The 'min' version is typically compressed, with whitespace removed, including line breaks. This means everything's on one line, which combined with shortening variable names to one or two letters, makes it practically impossible to read and debug. The point of which isn't necessarily to obfuscate intellectual property, but rather to load as quickly as possible as the file should be as small as possible. The other version should be readable and debuggable and that is why it is recommended when in development mode. ![]() Hope this helps. Actually it would not be difficult using ChessBoardJS as a PGN viewer when used in combination with the chess.js library. And (load_pgn) should be all you need to get started. Of course there are several PGN viewers around, however most of them I find are rather outdated, require additional browser plugins such as Java or are rather restrictive with what you can do with them. The ability to setup positions via a FEN string, or simply being able to move pieces on the board by dragging and dropping with no need for PGN files is awesome, and necessary for the current project I am working on.
