Point 4, bright pixel point 2, bright pixel point 3 and bright pixel point 4.
Step S105 believes according to the third place information of dark pixel point, the corresponding first position of three bright pixel points
Breath and second position information, determine fourth location information of the dark pixel point in VR display screens.
Fourth location information of the dark pixel point in VR display screens is the seat for the two-dimensional coordinate system set up on VR display screens
Scale value.
It is right by taking three bright pixels selected are bright pixel point 1, bright pixel point 2 and bright pixel point 3 shown in Fig. 6 as an example
Determine that the 4th location information of the point of the dark pixel shown in Fig. 6 a illustrates.Bright pixel point 1, bright pixel point 2 and bright pixel point 3 exist
First position information in the image of camera shooting is respectively (x1, y1), (x2, y2), (x3, y3).Bright pixel point 1, bright pixel point 2
It is respectively (x with second position information of the bright pixel point 3 on VR display screens1d, y1d), (x2d, y2d), (x3d, y3d).Dark pixel point
The third place information of a in the image that camera is shot is (x, y).Based on following calculating formula, the of dark pixel point a is calculated
Four location information (xd, yd),
xd=x1d+(x2d-x1d)*[(x-x1)/(x2-x1)]-calculating formula (1),
yd=y1d+(y3d-y1d)*[(y-y1)/(y3-y1)]-calculating formula (2).
Dark pixel point a and dark pixel point b in Fig. 6 are shown as white, it is only for embody its position in figure 6
It sets, is explained in order to illustrate, in fact, dark pixel point a and dark pixel point b are shown as black.
Dark pixel point b shown in Fig. 6 is located at same a line, in this case, above-mentioned meter with bright pixel point 1, bright pixel point 2
Formula (1), calculating formula (2) are equally applicable.
For the dark pixel point of the edge in camera imaging, the number of the bright pixel point due to surrounding the dark pixel point
Less than three, therefore, the bright pixel point completion three of the dark pixel point will be surrounded.For example, in the image of camera shooting, according to
The adjacent two bright pixels point of the dark pixel point determines third bright pixel point to be supplemented, and determines a third to be supplemented
The location information of bright pixel point in the picture, and, according to the adjacent two bright pixels point of the dark pixel point, determination is to be supplemented
Third bright pixel point, and determine the location information of third bright pixel point to be supplemented on VR display screens.Then, it recycles
Above-mentioned calculating formula (1), calculating formula (2), determine the 4th location information of the dark pixel point.The is supplemented in the image of camera shooting
When three bright pixel points, third bright pixel point can be located at same row with any bright pixel point in known two bright pixels point
Or same row, so that the region that these three bright pixel points surround can surround the dark pixel point.Meanwhile third bright pixel point
With positioned at go together or the spacing of the known bright pixel point of same column be equal to known two bright pixels point between spacing.In VR
The mode of third bright pixel point and the mode that third bright pixel point is supplemented in the image of camera shooting are supplemented on display screen
It is identical.
