Axis 14 also deviates certain angle, is located at tracker 6 within detection range in the position of Virtual Space.Software is clicked to start to adopt
Collect information, then rotary turnplate 4, rotate tracker 6 also in detection range in Virtual Space, stop adopting after rotating several weeks
Collect information, software can finally obtain the object for needing precise positioning by collected 6 coordinate points of tracker to be calculated
Absolute position of the head in Virtual Space, and the relative position with tracker 6 is obtained by variation.
Then bolt 7 is plugged, the screw 2 in nut cap 1 is removed, rotates shaft 14, shaft 14 is with moving sleeve 9 and sleeve 9
On object and tracker 6 rotate, then software click starts acquire information, rotate it is a few week after stop acquisition information, it is soft later
Part can be by calculating the elaborate position for needing the object other end of precise positioning in Virtual Space.
Since 4 points of known spherical surface calculate the centre ofs sphere and upper 3 points of the known circle principles for asking the center of circle, being put into Virtual Space is needed
Object coordinates point is placed on one end of object by the object model for wanting precise positioning, then the calculated object end point by before
Coordinate is given to object, then the other end of object is rotated, and finds out object one end by us to the other end of tail portion
Tail portion point.Can accurately in Virtual Space reconstructed object and the tracker 6 in reality relative position, and error is reduced
To 1mm, precision is substantially increased compared with originally.
