使用适用于 Android 的 Qualcomm AR SDK 进行远距离跟踪标记
是否有可能改进长距离/范围的跟踪？ 对于远距离，我的意思是大约 4-6 米。 当我用手机离开图像或标记时，跟踪突然丢失，尽管图像质量并没有那么差（特别是标记清晰可见）。
我可以采取什么措施来更好地远距离跟踪标记吗？无需在 DINA 3 上打印标记 ^^
Is it possible to improve the tracking on long distances / ranges?
With long range I mean around 4-6 meters.
When I move away from the image or marker with the phone suddenly the tracking is lost although the image quality is no that bad (especially the markers are clearly visible).
Can I anything do to better track Markers at long distances? Without printing the markers on DINA 3 ^^

基准标记（如 AR-Toolkit 风格）的经验法则是它们可追踪到标记宽度的约 10 倍。我假设 Qualcomm SDK 中的边缘标记也是如此，因为它们“跟踪”相同的外部矩形角。该实现基于格拉茨科技大学在学术会议上发表的 Studierstube，因此搜索他们的出版物可能会产生硬值。自然特征标记可以被进一步追踪，但不能达到“进一步”的精确定义——它在很大程度上取决于特征。
编辑：我找到了他们提出框架和分割标记的论文，但他们没有评估那里的跟踪距离。
The rule of thumb with fiducial markers (like AR-Toolkit style) is they're trackable to ~10x the marker width. I assume that the same is the case for the edge markers in the Qualcomm SDK since they "track" the same outer rectangle corners. The implementation is based on TU Graz's Studierstube which was published at academic conferences, so searching for their publications might yield hard values. Natural feature markers can be tracked further, but not to a precise definition of "further" - it depends heavily on the features.
Edit: I found the paper where they presented frame and split markers, but they didn't evaluate tracking distances there.
