I'am trying to make a board game with AR elements using vuforia. I have a Monopoly playing field (position is fixed on the table, camera position is also fixed) and flat chips, which i want to detect and attach a 3d model to them. How can i do that if chip's size is too small (1.5x1.5 cm)? Should i base on the game field cells positions somehow?
How to detect small chips in the board game
here some points about Factors that impact tracking multiple 2D markers, so I hope they could be helpful in your applicaiton case:
There are numerous factors that can affect Vuforia Engine SDK's ability to track multiple, simultaneous 2D target
- The device camera's field of view, which is determined by the camera's focal length and sensor size.
- Environmental lighting, including the presence of spectral reflections on the targets.
- The device camera's resolution setting (which depends upon the device). The higher the capture resolution, the better Vuforia's ability to extract feature points from the 2D target.
- The quality of the 2D targets:
For Image Targets, please review this article for tips on how to optimize: https://library.vuforia.com/articles/Solution/Optimizing-Target-Detection-and-Tracking-Stability
- For VuMarks, detection and decoding is driven by the contour+border+clear space+code elements. However, tracking quality will depend upon the accompanying artwork in the background/design area: https://library.vuforia.com/articles/Training/VuMark-Design-Guide
5. The device's processing power. Each additional target that is tracked simultaneously will increase the processing load on the CPU, which can usually be observed with a decreasing camera capture frame rate. At some point the processor may become saturated enough that it can no longer detect and track additional targets.
