Problems solved by technology

[0003] However, the existing method of controlling the rotation of the camera through an electric motor has many disadvantages
For example, the initial angle of the camera is not known before the rotation, so that it is impossible to determine how much the angle should be rotated to make the camera reach the front, rear or other arbitrary angle positions
In order to accurately reach the position of the front, rear or other arbitrary angles, the existing method usually uses the largest angle of rotation to achieve, thus ensuring that the camera can reach the position of the front, rear or other arbitrary angles. However, this This method is prone to the problem that the camera has been rotated to the end, but the electric motor is still rotating, causing the problem of motor idling, wasting power resources and deteriorating the mechanical properties of the motor
[0004] In addition, there is no method and product in the prior art that combines infrared gesture sensors and digital Hall sensors to realize gesture control camera rotation.

Embodiment 1

[0060] figure 1 It shows the first implementation flow chart of the method for controlling camera rotation by gestures provided by Embodiment 1 of the present invention; for the convenience of description, only the parts related to the present invention are shown.

[0061] In this embodiment, the method is applied to user equipment with a rotatable camera, including but not limited to mobile terminals such as mobile phones, tablet computers, and iPads. Wherein, in the rotatable camera, the camera is arranged on a rotatable device, and the rotatable device is located on the mobile terminal; a magnet is arranged on the rotatable device, and the magnet deviates from the rotatable device. The rotating shaft; and the digital Hall sensor is arranged on the main body of the mobile terminal and is arranged opposite to the magnet, which is used to sense the change of the magnetic field caused by the rotation of the magnet with the rotatable device, so as to determine the current offset...

Embodiment 2

[0078] Figure 4 It shows the first implementation process of step S103 in the method for controlling camera rotation with gestures provided by Embodiment 2 of the present invention. For the convenience of description, only the parts related to the present invention are shown.

[0079] When the digital Hall sensor monitors the offset angle of the camera, it is mainly realized by measuring the magnetic induction intensity of the magnet. Such as figure 2 In the structure shown, the distance between the digital Hall sensor and the magnet is the farthest, the magnetic field strength sensed is the weakest, the absolute value of the output value of the digital Hall sensor is the smallest, and the corresponding camera angle is 0 degrees. When the S pole of the magnet rotates to the N pole side, the distance between the digital Hall sensor and the magnet is the shortest, the sensed magnetic field strength is the strongest, the absolute value of the output value of the digital Hall s...

Embodiment 3

[0094] Image 6 It shows the second implementation process of step S103 in the method for controlling camera rotation by gesture provided in Embodiment 3 of the present invention. For ease of illustration, only the parts relevant to the present invention are shown.

[0095] In this embodiment, the camera control command is to control the camera to rotate to the front position.

[0096] Such as Image 6 As shown, step S103 includes:

[0097] In step S601, the initial output value of the digital Hall sensor is collected.

[0098] In step S602, it is judged whether the initial output value is smaller than a lower threshold.

[0099] Preferably, the lower threshold is the corresponding output value of the digital Hall sensor when the camera angle is 110 degrees. Therefore, when the collected initial output value of the digital Hall sensor is less than the lower threshold, it is determined that the camera is at the rear position, and step S403 is executed.

[0100] In step S6...

Abstract

The invention is applicable to the technical field of control, and provides a method and device for controlling the rotation of a camera with gestures and an infrared gesture sensor. The method includes: acquiring infrared intensity value change information collected by an infrared gesture sensor; obtaining the hand's swipe direction according to the infrared intensity value change information, and obtaining the hand's swipe direction from a preset mapping relationship according to the hand's swipe direction A camera control instruction corresponding to the swipe direction; controlling the camera to rotate to a position corresponding to the control instruction according to the control instruction. The above method uses the infrared gesture sensor to sense the swipe direction of the hand, realizes the gesture control camera to rotate to the front or rear position, and improves the control accuracy, and solves the problem that the existing technology of controlling the camera rotation is prone to motor idling The problem.

Description

technical field [0001] The invention belongs to the technical field of control, and in particular relates to a method, a device and an infrared gesture sensor for gesture control camera rotation. Background technique [0002] There are two ways to realize the rotatable camera currently on the market. One is manual rotation. There is no motor on this type of rotatable camera, and the angle of rotation cannot be controlled; the other is automatic rotation. This type of rotatable camera has a built-in electric motor, which can be controlled by controlling the rotation of the electric motor through a control chip. The angle by which the camera is rotated. [0003] However, the existing method of controlling the rotation of the camera by an electric motor has many disadvantages. For example, the initial angle of the camera is not known before the rotation, so that it is impossible to determine how much the angle should be rotated to make the camera reach the front, rear or othe...
