In this way, the lens distortion can be ignored.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-21987777582641163582010-11-18T21:18:42.511+02:002010-11-18T21:18:42.511+02:00@ "this pattern looks like the coding structu...@ "<i>this pattern looks like the coding structure from Anoto.</i>"<br /><br />Actually, this was my first thought as well. However it should not code each XY position by a unique code like Anoto. The coding length should be just long enough to not repeat itself for the different depths in the specified operating range.Vladimir Koifmanhttps://www.blogger.com/profile/01800020176563544699noreply@blogger.comtag:blogger.com,1999:blog-19092890.post-18029797338696804122010-11-18T20:52:30.112+02:002010-11-18T20:52:30.112+02:00this pattern looks like the coding structure from ...this pattern looks like the coding structure from Anoto.
