Electronic whiteboard construction using whiteboard and image-locating techniques
We use image-locating techniques and a traditional whiteboard with two cameras to construct an electronic whiteboard (EWB) with a size of corresponding to resolution. We employ two strategies achieve the goal: (1) we develope a modified scale and bilinear interpolation (MSBI) method for pen locating...

| description | We use image-locating techniques and a traditional whiteboard with two cameras to construct an electronic whiteboard (EWB) with a size of
corresponding to
resolution. We employ two strategies achieve the goal: (1) we develope a modified scale and bilinear interpolation (MSBI) method for pen locating and acceleration operation, and obtain high accuracy detection; and (2) a block parameter database (BPD) is created to improve the accuracy. For the BPD, we divide the whiteboard image into several blocks and record each block parameter (the
and
coordinates) to follow pen position calculation. Experimental results demonstrate that the MSBI method can correctly calculate the pen position. Additionally, the BPD strategy is better than the traditional method as it improves the accuracy and decreases the maximum detection error from
. The simulation results prove our method is an effective and low-cost EWB technique. |
