As shown in Figure 1, be the flow chart of the control method of a kind of The Cloud Terrace rotating speed of the embodiment of the present invention one, instituteThe method of stating comprises:
Step 101: the focal length multiple information that receives current video camera.
In step 101, choose arbitrary picture, use the image information of this picture of camera acquisition, adoptingIn the process of collection, adjust the focal length multiple information of video camera, will obtain different image informations. In order to coordinate cloudThe rate request that platform rotates, obtains high-quality image information, carries out in the focal length multiple information to video cameraWhen adjustment, the focal length multiple information of current video camera is sent to cradle head control equipment.
Step 102: determine the multiple block information that described multiple information is corresponding.
In step 102, because the focal length multiple information of video camera is an interval value, to same collectionWhen object is taken, adjust the multiple information of different focal lengths, the image information difference that correspondence obtains, itsIn, the numerical value of focal length multiple information is less, and the visual angle that gathers this object is larger, and the image information obtaining is more clearClear; The numerical value of focal length multiple information is larger, and the visual angle that gathers this object is less, and the image information obtaining is got over mouldStick with paste.
In order accurately to determine the focal length multiple information of video camera, first, can be by the focal length multiple letter of video cameraBreath is divided into different subintervals, by the corresponding pass between default focal length multiple information and demarcation interval quantitySystem realizes, and wherein, numerical information corresponding to multiple information is less, and demarcation interval quantity is more.
For example: taking 18 times of integrated cameras as example, the focal length multiple information of this video camera is 1 ~ 18 times,Also just mean the focal length that can adjust video camera within the scope of 1 ~ 18 times, obtain different image informations.Wherein, 1 ~ 18 times of focal length multiple information can be converted into the numerical information 0 ~ ZoomMax of machine recognition.
In the time that focal length multiple information is divided, wherein, for the quantity of different multiple demarcation intervals notWith. For example: focal length multiple information is 1 ~ 2 times, be divided into 16 grades; Focal length multiple information is 2 ~ 3 times,Divide 8 grades; Focal length multiple information is 3 ~ 4 times, divides 6 grades; Focal length multiple information is 4 ~ 5 times, divides4 grades; Focal length multiple information is 5 ~ 6 times, divides 2 grades; Remaining focal length multiple information is divided respectively 1 grade.
Focal length multiple information after dividing, numerical information and the multiple block information of machine recognition are set up to oneMapping table, and corresponding pass one by one between the numerical information of setting up each machine recognition and multiple block informationSystem, as shown in table 1:
| Focal length multiple information | The numerical information of machine recognition | Multiple block information |
| 1 ~ 2 times | Z0~Z15 | Interval 1 ~ interval 16 |
| 2 ~ 3 times | Z16~Z23 | Interval 17 ~ interval 24 |
| 3 ~ 4 times | Z24~Z29 | Interval 25 ~ interval 30 |
| 4 ~ 5 times | Z30~Z33 | Interval 31 ~ interval 34 |
| 5 ~ 6 times | Z34~Z35 | Interval 35 ~ interval 36 |
| …… | …… | …… |
| 18 times | ZMAX | Interval 48 |
Table 1
As can be seen from Table 1, the corresponding relation between focal length times number system information and demarcation interval quantity is:The quantity of 1 ~ 2 times of corresponding demarcation interval is 16 intervals, and the quantity of 2 ~ 3 times of corresponding demarcation intervals is 8Individual interval, the quantity of 3 ~ 4 times of corresponding demarcation intervals is 6 intervals, 4 ~ 5 times of corresponding demarcation intervalsQuantity is 4 intervals, and the quantity of 5 ~ 6 times of corresponding demarcation intervals is 2 intervals, afterwards each multipleThe quantity of demarcation interval corresponding to information value is 1 interval.
