Wherein the scaling mode includes equal scaling and free scaling.
And the scaling is to keep the ratio of the preset picture length to the preset picture width unchanged so as to ensure the truth of the projection picture.
The free scaling is that the ratio of the preset picture length to the preset picture width can be unchanged or changed, so that the projection picture is paved on the projection curtain.
In the specific implementation, as shown in fig. 1B, the intelligent projection device determines that the curtain length is 2 meters and the curtain width is 1.5 meters, and then the first ratio is 4: and 3, determining the preset picture length to be 0.6 m. If the preset frame width is 1.2 m, the second ratio is 1: 2, determining that the first ratio is different from the second ratio, and determining that the projection picture has a picture length of 0.75 m and the curtain width of 1.5 m as shown by P1 in fig. 1B according to that the scaling mode of the projection picture is equal scaling.
In the specific implementation, as shown in fig. 1B, the intelligent projection device determines that the curtain length is 2 meters and the curtain width is 1.5 meters, and then the first ratio is 4: and 3, determining the preset picture length to be 0.6 m.

Figure BDA0002221701250000082
wherein v is0Representing said preset unwinding speed, v1Representing said pre-display speed, y0Indicates the width of the curtain, y2And representing the frame width, wherein t represents the time length from the initial expansion time to the time for starting the display of the projection frame, and the initial display time of the projection frame is the time point after the initial expansion time passes the time length t.
And the fifth preset formula meets the condition that the projection picture is positioned in the middle of the projection curtain.
And the expansion action of the projection curtain can be completed or not while the projection picture is displayed.
Wherein, theThe projection picture also comprises any position located on the projection curtain, and the minimum distance y between any one point in the projection picture and the expansion point of the projection curtain only needs to be determined at the moment3At this time t is satisfiedt represents a time period from the initial development time to a time at which the projection screen starts to be displayed.
Wherein t represents a time length from the initial expansion time to a time when the projection screen starts to be displayed, for example: the time for the projection curtain to start to expand is 10: 00, i.e. the initial deployment time 10: 00, when the projection screen starts to be displayed after t is 3 seconds, the time for starting the display of the projection screen is 10: 03.
in a specific implementation, as shown in fig. 1E, knowing that the projection picture is located at the central position of the projection curtain, the intelligent projection device obtains a preset expansion speed v of the projection curtain0When the preset expansion time of the projection screen is determined to be equal to the preset display time of the projection screen, starting to expand the projection screen at a time point 14: 10 is the initial deployment time; the intelligent projection equipment is used for unfolding according to the preset unfolding speed v00.2 m/s, the initial deployment time 14: 10. width y of the curtain02.4 m, the frame width y21.6 m and preset formula

Determining the pre-display velocity v1The initial display time of the projection screen is a time point 14 at which the initial deployment time elapsed time period t is 2 seconds: 12.
further, as shown in fig. 1E, it can be obtained that the projection picture/the projection curtain at time point 14: the display/expansion is complete 22.
It can be seen that, in this example, the intelligent projection device obtains the preset expansion speed information of the projection screen, and then determines the pre-display speed and the initial display time of the projection screen according to the preset expansion speed, the initial expansion time, the screen width, and a fifth preset formula, where the pre-display speed and the initial display time of the projection screen are determined, and by introducing the preset formula, the pre-display speed and the initial display time of the projection screen are determined rapidly and accurately, and the high efficiency and the accuracy of screen display control are improved effectively.
In one possible example, after the smart projection device and the control unit control the smart projection device to start displaying the projection picture at the pre-display speed at the initial display time, the method further includes: and the intelligent projection equipment receives the change of the expansion speed of the projection curtain, and adjusts the display time and/or the display speed of the projection picture according to the change condition of the expansion speed of the projection curtain.
The adjusting of the display speed of the projection picture includes that if the expansion speed of the projection screen is increased, the display speed of the projection picture is increased relative to the pre-display speed, and if the expansion speed of the projection screen is decreased, the display speed of the projection picture is decreased relative to the pre-display speed.
The display time of the projection picture comprises initial display time of the projection picture and display completion time of the projection picture.
In a specific implementation, knowing that the projection picture is located at the middle position of the projection screen, the intelligent projection device obtains that the preset expansion speed of the projection screen is 0.2 m/s, and the expansion speed of the projection screen is changed to 0.4 m/s after the projection screen is expanded for 1 second, so that the initial display time of the projection picture is advanced, the display speed of the projection picture is faster than the pre-display speed of the projection picture, and meanwhile, the time-limited completion time of the projection picture is also advanced.
Therefore, in this example, if the intelligent projection device receives that the expansion speed of the projection screen changes, the display time and/or the display speed of the projection picture are/is adjusted according to the expansion speed change condition of the projection screen, which is beneficial to adjusting the display speed and/or the display time of the projection picture in time under the condition that the expansion speed of the projection screen changes, and is beneficial to meeting the display diversity of the projection picture and the high efficiency of the display control of the projection picture.
In one possible example, after the smart projection device and the control unit control the smart projection device to start displaying the projection picture at the pre-display speed at the initial display time, the method further includes: the intelligent projection equipment determines that the projection picture is displayed completely, and the projection curtain is unfolded completely; when a request for hiding the projection picture is received, acquiring preset shrinkage speed information of the projection curtain; the intelligent projection equipment determines the pre-hiding speed and the initial hiding time of the projection picture according to the preset shrinkage speed information and the picture information; and the intelligent projection equipment sends a request for starting contraction to the projection curtain and controls the intelligent projection equipment to start hiding the projection picture at the pre-hiding speed in the initial hiding time.
As can be seen, in this example, the intelligent projection device determines that the projection screen is displayed completely, and after the projection screen is unfolded completely; when a request for hiding the projection picture is received, acquiring preset shrinkage speed information of the projection curtain; the intelligent projection equipment determines the pre-hiding speed and the initial hiding time of the projection picture according to the preset shrinkage speed information and the picture information; the intelligent projection equipment sends a request for starting contraction to the projection curtain and controls the intelligent projection equipment to start hiding the projection picture at the pre-hiding speed in the initial hiding time; the method is beneficial to improving the high efficiency and convenience of the control of the projection picture when the projection picture needs to be hidden.
