In embodiments of the present invention, when multiple coordinate points continuous in time of brush tip and some model line of composition
Multiple continuous original points of item one by one successful match when, then illustrate that the motion profile of pen tip accords with completely with the model lines at this time
It closes, this section of lines for illustrating that user draws on target drawing paper are accurate.At this point it is possible to by this section of model lines carry out with
Targeted manner is shown, is accurate with this section of lines for prompting user just to draw.
Opposite, if having a coordinate points matching unsuccessful in multiple coordinate points continuous in time, to multiple seat
The corresponding model lines of punctuate are without any processing.At this point, user find electronic equipment lines that it has not been drawn just into
Row shows in a targeted way, then it is recognized that the inaccuracy that this section of lines are drawn, and then user can wipe and just draw
Lines are repainted, until electronic equipment shows the model lines in a targeted way.
By showing matched model lines in a targeted way, can be used family recognize at any time oneself imitation whether
Accurately, the lines for facilitating user inaccurate are modified, meanwhile, matched model lines, Ke Yiti are shown in a targeted way
Show which lines of user have drawn success, which lines is not drawn to function, facilitates user to draw remaining lines, and then make
User, which easily draws, copies the higher draft of model similarity with target.
Specifically, show that the model lines include: the color for changing model lines, overstriking display model in a targeted way
This lines, dotted line show that the modes different from the initial display mode of model lines such as model lines show the model lines.
For example, if the color of model lines is black, the model lines of successful match are shown in red.
Step 206- step 207 is more in the motion profile and model lines for constituting multiple location informations of pen tip
A original point is matched, and is the batch matching of multiple spot, and step 104- step 105 is by the location information of pen tip every bit
It is matched with the location information of each original point in model lines, is single-point matching.The batch of multiple spot matches, matching speed
It spends faster, and single-point matches, and matches more accurate.
Step 208, the first input in the preview interface of camera is received.
During imitation, when user in next step plan draw lines and previous step lines it is discontinuous, need to draw
When pen lifts from target drawing paper, alternatively, user takes paintbrush from target drawing paper when user needs temporarily to interrupt and copy
It rises, after user picks up paintbrush from target drawing paper, camera does not need that the position of pen tip is acquired and is tracked again.For
Informing camera no longer needs to be acquired pen tip position, and user can be to the first object button on camera preview interface
