Question

大家好，我对AR技术有疑问！

正好与我有问题的ARToolKit框架。我做了教程中的所有内容，但是应用程序无法识别我所投入的符号。

教程页面：link

我创造了什么： - 关于symbol（filename.patt）的模式文件，并将其添加到\ Data \下的项目中 - 使用mk_patt.exe识别图像我想要作为源。 - 修改了来源：

markerID = ARToolKit.getInstance（）。addMarker（＆＃34; single; Data / patt.eslogo; 80＆＃34;）;

但我不知道自己还需要做些什么。顺便说一下，这是一个例子，使用原始源程序，程序在符号上工作并绘制立方体。并且新的模式文件是相同的样式，所以这不是问题。

有什么想法吗？我没有找到有用的视频，其中包括确切的方法

更详细：

首先，在我使用mk_patt.exe之后，我给了＆＃39; camera_para.dat＆＃39;该项目的创建和添加＆＃39; patt.slogo＆＃39;模式文件，我将此行修改为：

markerID = ARToolKit.getInstance().addMarker("single;Data/patt.slogo;80");

这是绘图方法的要点：

public void draw（GL10 gl）{
...

if（ARToolKit.getInstance（）。queryMarkerVisible（markerID））{

cube.draw（GL10 gl）;
顺便说一句，这是公众＆＃39; kosiara＆＃39;例如来自git：link

Answer 1

I tried with another pattern file and it's working, but the process when i was created the pattern about a symbol was the same like now, and i don't know why the program can't recognize the symbol what i used with the same logic.

Conclusion: Eventually the program working with another symbol what i created with wider line than before and that is the point.
