0, related instructions: Let's take a look at the relevant instructions first. In the "jsxyhelu.cnblogs.com/Project actual Combat" column appears in the needs, pictures and other resources, are I browse the website, forum and other sites through the formal channels to obtain the real needs. Personally feel more interested, but because of time or work conflict oneself did not go to pick up these items. But because these requirements are very valuable to achieve, so after a period of time, still took out to practice a practiced hand, and achieved the core module. Hope to be able to give the visitors some inspiration. If you think these pictures and resources are not suitable here, please contact me in time ([email protected]), I will deal with it in time. In addition, I will make the core code and technical details as clear as possible, I think this is the most valuable way. If you need the original code, you can also contact me.
first, the original needs:There are a number of ways to get data on the screen, one of which is to directly set the location of the area, constantly on the fixed position, and then through the image recognition method. This method is widely used, and when the data to be identified is not particularly complex, the recognition efficiency can be very high. Here I try to achieve the above functions.
Second, the Software design:based on the functionality that the software needs to implement, I chose to solve the problem by using the "CSharp Authoring interface +opencv writing core functions" mode. Chsarp, the main function is to "get screen coordinates, get the designated area every time" effect; OpenCV convenience is mainly to enhance and identify the intercepted area. by modifying the existing screen screenshot software, CSharp has achieved this goal:(1)To achieve the purpose of data testing, write a form that automatically generates numbers to move around. Of course, the effect of this form is relatively simple effect, in fact, may appear more complex background, or need to recognize the character format more difficult to identify. (2) (3)(4)Then there is the recognition interface, here is the modification of an existing screenshot software to do. The main thing is to call the existing class library and make it into a dynamically intercepted data type. (5)Specifically, you can watch the video. (6)
Iv. Reflection of the summary:Such a procedure, the idea is clear, the function is also relatively single, if meets the suitable occasion, may be able to play certain role. The main problem encountered in the process of writing is the integration of tesseract, encountered the "ambiguous symbol" error, in addition, in C # call C + + DLL library process of parameter transfer problem is not very good solution, if there is a study on this aspect of the friend, very much hope to get guidance. Thanks for reading and hope to be helpful. Http://pan.baidu.com/s/1eQAlrNG
