Problems solved by technology

[0004] The above-mentioned method of using a camera to recognize gestures is simple and easy, and belongs to non-contact gesture recognition, but the two-dimensional image acquired by the camera has no depth information, it is difficult to distinguish the hand and the background on the image, and the accuracy of gesture recognition is not high. And if the hand is blocked, the gesture cannot be recognized, and the user's application experience is not good

Embodiment 1

[0022] figure 1 It is a flow chart of a method for controlling photographing based on gestures provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation where the photographing area is determined by recognizing gestures. The method can be executed by a device for controlling photographing based on gestures. The device It is configured in a mobile terminal such as a mobile phone, a tablet computer or a personal computer. Described method specifically comprises the steps:

[0023] Step 110, using the ultrasonic sensor in the mobile terminal to recognize the gesture action of the user.

[0024] Wherein, the ultrasonic sensor includes at least one receiving end and at least one transmitting end. The ultrasonic signal is transmitted through the transmitting end, and the ultrasonic reflection signal reflected by the hand is received through the receiving end. For example, in order to acquire the coordinates of gesture actions in three-dimen...

Embodiment 2

[0032] Figure 2a It is a flow chart of a method for controlling photographing based on gestures in Embodiment 2 of the present invention. On the basis of the above-mentioned embodiments, the technical solution of this embodiment will describe in detail how to control the camera to capture the image corresponding to the shape.

[0033] see Figure 2a As shown, the method for taking pictures based on gesture control specifically includes the following steps:

[0034] Step 210, using the ultrasonic sensor in the mobile terminal to recognize the gesture of the user, and determine the shape indicated by the gesture.

[0035] Step 220: Control the camera to receive the shape indicated by the gesture, and identify the area defined by the gesture.

[0036] The terminal controls the camera to receive the shape indicated by the gesture action, and defines a shooting area according to the coordinates of the gesture position. optional, see Figure 2b As shown, the camera may also dr...

Embodiment 3

[0055] image 3 It is a schematic structural diagram of a gesture-based camera-taking device in Embodiment 3 of the present invention. The devices include:

[0056] Gesture action recognition unit 310, configured to use the ultrasonic sensor in the mobile terminal to identify the user's gesture action;

[0057] a shape determining unit 320, configured to determine the shape indicated by the gesture;

[0058] The image capture unit 330 is configured to control the camera to capture an image corresponding to the shape.

[0059] In the technical solution of this embodiment, the gesture action recognition unit 310 utilizes the ultrasonic sensor in the mobile terminal to identify the gesture action of the user, the shape determination unit 320 determines the shape indicated by the gesture action, and the image capture unit 330 is used to control the camera to capture the gesture. The image corresponding to the shape solves the problem of low recognition accuracy and poor user ex...

Abstract

The invention discloses a gesture-based photographing control method and device. The method comprises the following steps: identifying a gesture action of a user by use of an ultrasonic sensor in a mobile terminal; determining a shape indicated by the gesture action; and controlling a camera to photograph an image corresponding to the shape. By adopting the gesture-based photographing control method and device disclosed by the invention, the problems of the existing vision-based gesture identification method of low identification precision and poor user experience are solved, the gesture action is accurately identified, a photographing function is achieved according to the identified gesture action, and an effect of enhancing the interest and the user experience is achieved.

Description

technical field [0001] Embodiments of the present invention relate to image capturing technologies, and in particular, to a method and device for controlling photographing based on gestures. Background technique [0002] With the advancement of the intelligentization of electronic products, intelligent terminals with human-computer interaction functions are more and more widely used in people's life and production. People's requirements for the convenience of human-computer interaction are getting higher and higher, and as a natural and intuitive form of expression, gesture recognition technology has become an indispensable key technology for the development of a new generation of human-computer interaction products. [0003] At present, when taking pictures based on gesture recognition, first, a frame of image is captured by the camera as the background image; secondly, the camera is used to track the user's hand in the lens, and then multiple frames of images are obtained,...
