我正在使用Android上的ARToolKit示例应用程序ARSimple。我不想跟踪hiro标记,而是要跟踪NFT标记。所以我正在使用:
int testMarker = ARToolKit.getInstance().addMarker("2d;data/nft/Test.jpg");
根据文档,这是添加NFT标记的正确方法(除非我错过了什么)。
这给出以下输出:
E/libARWrapper: ARController (native): [error]Error: Unknown marker type '2d' in config '2d;data/nft/Test.jpg'.
E/libARWrapper: ARController (native): [error]Error: Failed to load marker.
这似乎表明这不是正确的方法。那么,如何添加NFT标记?
编辑:
通过应用Thor_Bux答案的更改,我的代码变为:
public boolean configureARScene() {
pinballMarker = ARToolKit.getInstance().addMarker("nft;data/pinball");
if (pinballMarker == -1) return false;
return true;
}
文件
pinball.fset
,pinball.fset3
和pinball.iset
位于我的assets/Data
目录中。错误消息如下:
E/libar: Error: unable to open file 'data/pinball.iset' for reading.
E/libar: Error opening file 'data/pinball.iset'.
E/libARWrapper: ARController (native): [error]Error reading data from data/pinball.fset
E/libARWrapper: ARController (native): [error]Error: Failed to load marker.
编辑:
卸载应用程序后,如建议的Thor_Bux,并将配置更改为
nft;Data/pinball
,将加载标记。但是仍然出现错误消息:E/libARWrapper: ARController (native): [error]Loading Data/pinball.fset.

即使标记似乎已成功加载,也无法通过
queryMarkerVisible()
进行检测。此外,尽管场景已成功配置,但似乎从未调用SimpleRenderer#draw()
。 最佳答案
从上一个对话中,您似乎正在使用此示例代码,并且想要更改此行代码以使其跟踪NFT标记:
https://github.com/artoolkitx/artoolkit5/blob/master/AndroidStudioProjects/ARSimpleProj/aRSimple/src/main/java/org/artoolkit/ar/samples/ARSimple/SimpleRenderer.java#L72
您还指出,您已经按照以下说明创建了所需的NFT .fset和.iset文件:https://archive.artoolkit.org/documentation/doku.php?id=3_Marker_Training:marker_nft_training
现在需要做的是将fset和iset文件添加到项目的“ assets / Data /”目录中。 (在hiro.patt旁边)
然后,将提到的代码行更改为此:nft;data/pinball
此处记录:
