Doing a project recently, put down the workpiece the workpiece, the location and does not comply with the design values,
What do you want to be a software compensation procedures,
By measuring the two Angle of the workpiece coordinate data, to find the center of the work pieces of artifacts, y offset and rotation Angle,
Hope to have experience in counsel, thank

O Angle when applied triangle knowledge can be obtained

The junior high school geometry application I have returned to the math teacher, you can ask her to come back.

For example on the left on behalf of A, right on behalf of B, her left on behalf of the C, right on behalf of D, X and Y coordinates is container, offset according to now - you can get the original; X - x y - y
Rotation Angle, By - Ay=right-angle triangle height, slope length, Bx - Ax=triangle and the length, when calculating the Angle, it is not problem, forget to triangle formula, you look for it

This is very simple, just put a tangent function,
Double r=Math. Atan (20/20);

But see you rotate Angle, your measurements seem to have a problem, another due to the rotation and translation problems, you need a set of formula, gives you a vector algorithm for reference,
'* * * * * * (x1, y1) for rotating arbitrary point, (x2, y2) as the center of rotation, if it is clockwise Angle is theta, the rotation (x, y) as the new coordinates * *
'* * * * * * x=(x1, x2) cosine theta - (y1, y2) sine theta + x2 * *
'* * * * * * y=(x1, x2) sine theta + (y1, y2) cosine theta + y2

What is inverse trigonometric function, trigonometric function? Measure the same edge two vertices values, to calculate the horizontal and vertical deviation between two points, can calculate the rotation Angle, according to the center of rotation Angle can calculate the relative coordinates, and then calculate the deviation,
