Duration prediction obtains first dragging speed of the new drag events in first dimension, and according between described second
Gauge obtains second dragging speed of the new drag events in second dimension from first duration prediction.
Step S43, according to first dragging speed, it is described second dragging and the new drag events and it is described after
The second duration between the generation moment of drag events determines the predicted position of the new drag events.
Still referring to above-mentioned example, it is assumed that the N+1 times drag events is detected, if the reality of the N+1 times drag events
Position is P2 (x2, y2), and the generation moment is t2.It then, can be according to the moving direction vector and the first duration calculation calculated above
The predicted position P2'(x2', y2' of the N+1 times drag events).In detail, it can be calculated by following calculating formula:
Wherein, Δ x/ Δ t indicates actual first dragging speed from n-th drag events in first dimension,
When implementing, which can be predicted in first dimension as the N+1 times drag events
First dragging speed.It accordingly, can prediction using Δ y/ Δ t as the N+1 times drag events in second dimension
Second dragging speed.
The corresponding dragging duration of the N+1 times drag events are as follows: t2-t1, i.e., described second duration.In the case, it predicts
The first dragging speed and the product of the second duration be dragging distance of the N+1 times drag events in first dimension,
Second dragging speed of prediction and the product of the second duration be dragging of the N+1 times drag events in second dimension away from
From according to dragging distance of the N+1 times drag events in first dimension and second dimension, that is, can determine institute
State the predicted position of the N+1 times drag events.
Step S44, when the predicted position reaches preset value at a distance from the physical location of the new drag events,
It is picture captured when the camera is in the predicted position by the frame updating of the 3-D image.
When implementing, it can be determined that whether the distance of predicted position P2 ' and P2 reaches the preset value, if do not reached
It arrives, indicates the N+1 times drag events predicted mistake, it may not be necessary to update the picture of 3-D image.It, can be right if reached
