<FIG> is a flowchart showing an image acquisition method according to a first exemplary embodiment. The image acquisition method of the embodiment may be applied to a terminal device (for example, a smart phone, a smart camera, a tablet computer, a wearable device and the like). As shown in <FIG>, the method includes the following steps S101-S103.

In step S101, augmented reality (AR) anchor information in current scene is acquired in response to a first image acquisition instruction of a terminal device.

For example, when taking photos with a terminal device, a user may trigger an operation of opening a camera application in the terminal device, and then the terminal device may acquire an augmented reality (AR) anchor information in a current scene in response to a first image acquisition instruction of the terminal device.

An AR anchor to which the AR anchor information belongs is configured to indicate first image capturing information of a camera device when acquiring a sample image, and the first image capturing information includes spatial coordinate information and/or orientation information. For examiner, the spatial coordinate information and/or orientation information is spatial coordinate information and/or orientation information of a camera device that was used by other users before to acquire the sample image, and for example, the orientation information is a image capturing direction of the camera device, etc..

For example, the content of the above AR anchor may be set by a developer or user according to actual needs, for example, may be set to be at least one of a cloud anchor, a photo, a text description, and a graphic mark, which is not limited in the embodiment.

In the embodiment, after the AR anchor is displayed in the viewing frame of the terminal device according to the AR anchor information, image acquisition may be performed according to the first image capturing information indicated by the AR anchor.

For example, after the AR anchor is displayed in the viewing frame of the terminal device, the user may adjust the image capturing information of the terminal device according to the AR anchor, for example, may adjust the spatial coordinate information and/or orientation information of the terminal device and the like, and then the image information in the current viewing frame may be acquired after the image capturing information is adjusted.

In an embodiment, the above AR anchor may further include an AR viewing indicating frame. The AR viewing indicating frame therein may include a sample image corresponding to the AR anchor. On such basis, the terminal device may start the camera device of the terminal device to perform the image acquisition in response to detecting that the viewing frame matches the AR viewing indicating frame.

For example, the user may be reminded to adjust the image capturing information of the terminal device, such as the spatial coordinate information and/or orientation information of the terminal device, according to the displayed AR anchor, to make the viewing frame of the terminal device and the AR viewing indicating frame coincide with each other, so that the camera device of the terminal device may be started to perform image acquisition.

In an embodiment, the above first image capturing information may further include at least one of a filter type and a zoom factor.

In an exemplary embodiment, the communication component <NUM> receives a broadcast signal or broadcast related information from an external broadcast management system via a broadcast channel. In an exemplary embodiment, the communication component <NUM> further includes a near field communication (NFC) module to facilitate short-range communication. For example, the NFC module may be implemented based on radio frequency identification (RFID) technology, infrared data association (IrDA) technology, ultra-wideband (UWB) technology, Bluetooth (BT) technology and other technologies.

In an exemplary embodiment, the device <NUM> may be implemented by one or more application specific integrated circuits (ASICs), digital signal processors (DSP), digital signal processing devices (DSPDs), programmable logic devices (PLDs), field programmable gate arrays (FPGAs), controllers, microcontrollers, microprocessors or other electronic components to implement the above-mentioned image acquisition method.

Claim 1:
An image acquisition method, wherein the method comprises:
acquiring (S101, S401) augmented reality (AR) anchor information in current scene in response to a first image acquisition instruction of a terminal device including a camera, wherein an AR anchor to which the AR anchor information belongs is configured to indicate first image capturing information of a camera device when acquiring a sample image, and the first image capturing information comprises spatial coordinate information and/or orientation information of a camera device that was used by other users before to acquire the sample image;
displaying (S102) the AR anchor in a viewing frame of the terminal device according to the AR anchor information; and
performing (S103, S404) image acquisition according to the first image capturing information indicated by the AR anchor,
characterized in that the performing (S103, S404) image acquisition according to the first image capturing information indicated by the AR anchor comprises:
starting (S201) a countdown of a preset time duration in response to detecting that second image capturing information of the terminal device matches the first image capturing information; and
acquiring (S202) image information in the viewing frame of the terminal device after the countdown ends.
