imageTarget识别图和摄像头之间的距离

识别图拿远一点，摄像头就丢失图片了。能不能离得远一些，还能正常触发效果？？距离能设定吗？

 

EN:When the image is taken away, the camera loses the picture. Can it be far away, and can trigger the effect normally?? Can the distance be set?

 

The detection distance will be based on multiple variables such as quality of image, type of lighting you have, and how reflective your surface is. Is there a specific distance you are wanting to detect from? If you can start closer to the object and want to move back further from the target, I'd recommend using extended tracking: https://library.vuforia.com/content/vuforia-library/en/articles/Training/Extended-Tracking.html
