Problems solved by technology

[0017] The embodiment of the present invention provides a method and device for controlling the pan / tilt, which are used to solve the problem that in the prior art, the azimuth button cannot quickly and accurately locate the azimuth information of the image, resulting in too long operation time for the azimuth button and low efficiency. And the poor coordination between the azimuth button and the zoom button when the operation is triggered leads to the problem that the quality of the collected image information is not high

Embodiment 1

[0042] Such as figure 2 As shown, it is a flow chart of a control method of a pan-tilt according to Embodiment 1 of the present invention, and the method includes:

[0043] Step 101: Obtain panorama information of an object to be collected.

[0044] In step 101, after determining the object to be collected, an instruction to collect panorama information within the range is sent to the pan / tilt controller to obtain the panorama information of the object to be collected, specifically including:

[0045] First, determine the maximum and minimum values ​​of pan and tilt, and the maximum and minimum values ​​of vertical rotation of the gimbal.

[0046] Specifically, the maximum horizontal rotation of the gimbal is 360°, and the minimum horizontal rotation is 0°; the maximum vertical rotation of the gimbal is 90°, and the minimum vertical rotation is 0°.

[0047] Secondly, control the operation of the pan-tilt, and collect the image information passing by during the operation of ...

Embodiment 2

[0092] Such as Figure 6 As shown, it is a schematic structural diagram of a control device for a cloud platform according to Embodiment 2 of the present invention, the device includes: a capture module 11, a determination module 12, a calculation module 13 and a control module 14, wherein:

[0093] The capturing module 11 is used to acquire the panorama information of the object to be captured.

[0094] The determination module 12 is configured to select an area in the panorama information, and determine the center coordinate information and area area information of the area.

[0095] The calculation module 13 is configured to calculate and obtain parameter information for controlling the pan / tilt according to the center coordinate information and the area area information.

[0096] The control module 14 is used to control the operation of the pan-tilt by using the obtained parameter information, and locate the image information in the area when the pan-tilt is in operation....

Abstract

The invention discloses a cradle head control method and device. The main technical scheme is that panorama information is an objected to be acquired is obtained, which means all image information in the horizontal rotation range and the vertical rotation range of the cradle head are obtained, so that by selecting one image region from the obtained image information, the horizontal rotation parameters and vertical rotation parameters for controlling the cradle head can be determined fast, so that the cradle head posture change rate can be improved; by combining with the control of zoom parameters of the cradle head, the image information in the region can be obtained fast, the coordination consistency between the cradle head rotation and the cradle head control lens zooming can be realized, and the cradle head control flexibly can be improved.

Description

technical field [0001] The invention relates to the field of image information collection, in particular to a control method and equipment for a pan-tilt. Background technique [0002] The pan / tilt is a support device installed and fixed on the camera equipment. The range of image information collected is determined by controlling the pan / tilt. Among them, the pan / tilt is divided into two types: fixed pan / tilt and electric pan / tilt. The fixed gimbal is suitable for a small image collection range, and the amount of image information collected is small; the electric gimbal is suitable for scanning and collecting image information in a large range, and the amount of image information collected is large. [0003] The electric pan-tilt is controlled by two motors, one motor controls the horizontal movement of the pan-tilt, and the other motor controls the vertical movement of the pan-tilt, respectively receiving control instructions from the camera equipment controller to control...
