| Abstract: | The accuracy of subpixel target image location is an important factor that contributes to the overall precision of three dimensional measurement when using CCD cameras. This shorter contribution reports the effect of an electrical adjustment of a frame grabber that results in a significant and systematic error in the accuracy of target image location using some target location methods. |
