The following takes a terminal device as an example to exemplarily describe the method for determining the position of the infrared hotspot provided by the embodiment of the invention.

The terminal in the embodiment of the present invention may be a terminal having an operating system. The operating system may be an Android (Android) operating system, an ios operating system, or other possible operating systems, and embodiments of the present invention are not limited in particular.

The following describes a software environment applied to the method for determining the location of an infrared hotspot according to the embodiment of the present invention, by taking an android operating system as an example.

Fig. 1 is a schematic diagram of an architecture of a possible android operating system according to an embodiment of the present invention. In fig. 1, the architecture of the android operating system includes 4 layers, which are respectively: an application layer, an application framework layer, a system runtime layer, and a kernel layer (specifically, a Linux kernel layer).

The application program layer comprises various application programs (including system application programs and third-party application programs) in an android operating system.

The application framework layer is a framework of the application, and a developer can develop some applications based on the application framework layer under the condition of complying with the development principle of the framework of the application.

The system runtime layer includes libraries (also called system libraries) and android operating system runtime environments. The library mainly provides various resources required by the android operating system. The android operating system running environment is used for providing a software environment for the android operating system.

The kernel layer is an operating system layer of an android operating system and belongs to the bottommost layer of an android operating system software layer. The kernel layer provides kernel system services and hardware-related drivers for the android operating system based on the Linux kernel.

Taking an android operating system as an example, in the embodiment of the present invention, a developer may develop a software program for implementing the method for determining the location of the infrared hotspot provided in the embodiment of the present invention based on the system architecture of the android operating system shown in fig. 1, so that the method for determining the location of the infrared hotspot may operate based on the android operating system shown in fig. 1. Namely, the processor or the terminal device can realize the method for determining the position of the infrared hotspot provided by the embodiment of the invention by running the software program in the android operating system.

The method for determining the position of an infrared hotspot according to the embodiment of the present invention is described below with reference to a flowchart of the method for determining the position of an infrared hotspot shown in fig. 2, where as shown in fig. 2, the method for determining the position of an infrared hotspot according to the embodiment of the present invention includes steps 201 and 202:

step 201: in the case where the first interface displays the first image, the terminal device receives a first input of a user.

In an embodiment of the present invention, the first input of the user specifically includes: the user clicks on the first interface, or the user presses on the first interface, or a specific gesture of the user on the first interface, or a clicking operation of the user on a specific control, and the like.

The clicking operation can be a single-click operation, a double-click operation or a continuous clicking operation for a preset number of times. The specific gesture may be any one of a single-click gesture, a sliding gesture, a pressure recognition gesture, a long-press gesture, a double-press gesture, and a double-click gesture.

Step 202: in response to the first input, the terminal device displays a first identifier at a first position of the first image according to the second image.

In an embodiment of the present invention, the first image is an image collected by a non-infrared camera, the second image is an image collected by an infrared camera, and the first image and the second image are images collected by the non-infrared camera and the infrared camera with respect to the same shooting object, respectively.

In an embodiment of the present invention, the first image may be an image acquired by a non-infrared camera in a bright environment, and the second image may be an image acquired by an infrared camera in a dark environment. The bright environment refers to an environment where the ambient light intensity is greater than a preset light intensity, and may be under the sun, in the daytime, sunlight penetrates into indoor space, and the like.

For example, after selecting the position W to be photographed, the user may use the non-infrared camera to capture the non-infrared image in a bright environment, then convert the photographing environment from the bright environment to a dark environment (e.g., turn off the light, pull the curtain, etc.), and then continue to capture the infrared image in the dark environment using the infrared camera at the position W. And then, the terminal equipment analyzes the infrared image to extract all infrared hot spots, and then marks the position of the target infrared hot spot on the non-infrared image by using the first identification so as to prompt a user to check and eliminate hidden dangers.

For example, in a case where an infrared camera and a non-infrared camera are integrated in a terminal device, a user needs to capture a non-infrared image and an infrared image at the same position by using the same photographing posture. Specifically, taking a mobile phone as an example, the mobile phone may capture a posture of the mobile phone when taking a picture for the first time, and then take a picture for the second time in the same posture. For example, the posture during photographing can be obtained through the mobile phone Gsensor, that is, whether the placing direction of the mobile phone is the same as the placing direction of the mobile phone during the previous photographing is judged, and the user is reminded to adjust the placing direction of the mobile phone until the placing direction of the mobile phone is the same as the placing direction of the mobile phone during the previous photographing, so as to obtain two images aiming at the same photographing object.

In an embodiment of the present invention, the first image and the second image are respectively images collected by a non-infrared camera and an infrared camera for a same shooting object, where: the shape and position of the object included in the first image are all the same as those of the object included in the second image, or the probability that the part of the first image having the same shape and position as those of the object in the second image occupies the total object is greater than a preset threshold. For example, the preset threshold may be 90%, that is, 90% or more of the parts of the first image that are identical in shape and position to the photographic subject and the second image that are identical in shape and position to each other, and the first image and the second image are regarded as images acquired for the same photographic subject.

It should be noted that the position of the subject may be a position of the subject in the image or a relative position between the subject and another subject.

In an embodiment of the present invention, the second image includes: m infrared hot spots, wherein the infrared temperature corresponding to each infrared hot spot is greater than or equal to a preset threshold value, and M is greater than or equal to 1.

In an embodiment of the present invention, the first position of the first image is a position where a target infrared hot spot is located, and the target infrared hot spot is at least one of the M infrared hot spots.

In an embodiment of the present invention, the first identifier may be information such as a pattern, a picture, and a text.

In an example, if the first mark is a pattern, the shape of the pattern may be any possible shape, such as a circle, a rectangle, a triangle, a diamond, a circle, or a polygon, which may be determined according to actual use requirements, and the embodiment of the present invention is not limited thereto. Further, the pattern may be displayed on the first image with high or low brightness.

In the embodiment of the present invention, since the first image and the second image are images captured by the non-infrared camera and the infrared camera respectively for the same shooting object, that is, the first image and the second image are images captured for the same scene (for example, images shot by the non-infrared camera and the infrared camera for the same corner of a certain room), the position of each infrared hot spot in the second image is associated with the position of the infrared hot spot in the first image.

Illustratively, after the terminal device determines M infrared hot spots in the second image, the positions of the infrared hot spots in the first image can be determined, and by analyzing the physical structure of the object, the objects at the positions of the infrared hot spots in the first image are identified, and the target infrared hot spots are screened out.

Example 1: taking the example of finding a hidden camera, in general, there are the following items in a room that may be installed with the hidden camera: lighters, cartoon pendants, bath foam, beverage cans, smoke detectors and the like. Therefore, the terminal equipment can screen out the possible positions of the hidden camera according to the prior knowledge, and check the hidden camera one by one to eliminate hidden dangers.

Example 2: the terminal device can determine whether each infrared hotspot is overlapped with the position of the normal circuit module, so as to determine whether the infrared hotspot is a target infrared hotspot. For example, if the infrared hot spot S1 overlaps with a normal circuit module, it is determined as a normal infrared hot spot, and for example, a circuit of a television generates heat, so that an infrared hot spot is generated, and at this time, the infrared hot spot can be removed; if the positions of the infrared hot spot S1 and the normal circuit module are not overlapped, namely the position of the infrared hot spot S1 is not supposed to have a circuit, the infrared hot spot is determined as a target infrared hot spot, for example, a place where an object such as a bed head, a wardrobe and the like cannot have a circuit, and the infrared hot spot is detected to be present, so that the infrared hot spot is determined as the target infrared hot spot.

For example, the terminal device may mark only the location of the target infrared hotspot on the first interface. As shown in fig. 3, after an RGB image of a room a is collected by an RGB camera of a mobile phone, the image is displayed on a first interface (31 in fig. 3), and at this time, when a user clicks the first interface 31, two target infrared hot spots, namely, a hot spot a (as shown in fig. 3, the hot spot is located on a wall surface) and a hot spot B (as shown in fig. 3, the hot spot is located on a wine bottle on a tea table) are displayed on the first interface and are identified by circles.

Optionally, in an embodiment of the present invention, the step 201 specifically includes the following steps:

step 201 a: the terminal device receives a first input of a user when the first split screen displays a first image and the second split screen displays a second image.

The first interface is an interface in the first split screen.

In the embodiment of the invention, the terminal device can split the interface of the display screen of the terminal device into the first split screen and the second split screen in a split screen mode, wherein the first split screen displays the first image, and the second split screen displays the second image.

For example, the terminal device may display the first image and the second image separately in a split screen format. As shown in fig. 4, after the user acquires an RGB image of the room a through the RGB camera of the mobile phone and acquires an infrared image of the room a at the same angle through the infrared camera of the mobile phone (the image is indicated as an infrared image by oblique lines in fig. 4), the RGB image is displayed on the interface of the first split screen (i.e., 31 in fig. 4), and the infrared image is displayed on the interface of the second split screen (i.e., 32 in fig. 4). At this time, when the user clicks the first interface 31, two target infrared hot spots, i.e., a hot spot a (as shown in fig. 4, the hot spot is located on a wine bottle on a tea table) and a hot spot B (as shown in fig. 4, the hot spot is located on a wall surface) are displayed on the first interface and are identified by circles.

Further optionally, in an embodiment of the present invention, after the step 201a, the method further includes:

step 201b 1: the terminal device receives a second input of the user.

In the embodiment of the present invention, the second input is used to trigger the terminal device to display the second image in a full screen.

For example, the second input may be an operation of the user on the second split screen, an operation of the user on the first split screen, an operation of the user on a specific control on the first split screen or the second split screen, a specific gesture of the user on the first split screen or the second split screen, or the like.

Step 201b 2: and the terminal equipment responds to the second input, exits the split screen state and displays the second image in a full screen mode.

Further optionally, in the embodiment of the present invention, the first image is a real-time non-infrared image currently acquired by a non-infrared camera; or, the second image is a real-time infrared image currently acquired by the infrared camera. For example, the terminal device may acquire an infrared image acquired by the infrared camera in advance, and then, when the non-infrared camera starts to take a picture, the terminal device displays a real-time non-infrared image (i.e., a preview image acquired by the non-infrared camera) acquired by the non-infrared camera currently on the first split screen, and displays an infrared image acquired by the infrared camera in advance on the second split screen, that is, the interface of the first split screen is a preview interface; or the terminal device may acquire a non-infrared image acquired by the non-infrared camera in advance, and then, when the infrared camera starts to take a picture, the non-infrared image acquired by the non-infrared camera in advance is displayed on the first split screen, and a real-time infrared image (i.e., a preview image acquired by the infrared camera) currently acquired by the infrared camera is displayed on the second split screen, that is, the interface of the second split screen is a preview interface.

Further optionally, in the embodiment of the present invention, when the infrared camera starts to take a picture, the terminal device may display a real-time infrared image (i.e., a preview image acquired by the infrared camera) currently acquired by the infrared camera on the second split screen, and display a panoramic image acquired by the non-infrared camera in advance on the first split screen. The panoramic image is synthesized by a plurality of continuous first images, and the plurality of first images are images shot by the non-infrared camera in the panoramic mode.

For example, the first split screen may be played from one end of the panoramic image in a video playing mode, and the content of the panoramic image displayed in real time in the first split screen is associated with the preview screen currently displayed in the second split screen (i.e. the shooting objects of the two are the same), for example, the playing speed of the panoramic image is the same as the moving speed of the screen in the preview interface.

Optionally, in the embodiment of the present invention, the target infrared hot spot includes N infrared hot spots, where N is greater than or equal to 1, and N is less than M. At this time, the method further includes the steps of:

step A1: and the terminal equipment displays the second identification on M-N second positions of the first image according to the second image.

The M-N second positions are positions of other infrared hot spots except the target infrared hot spot in the M infrared hot spots in the first image.

In an embodiment of the present invention, the second identifier may be information such as a pattern, a picture, and a character.

In an example, if the second mark is a pattern, the shape of the pattern may be any possible shape, such as a circle, a rectangle, a triangle, a diamond, a circle, or a polygon, which may be determined according to actual use requirements, and the embodiment of the present invention is not limited thereto. Further, the pattern may be displayed on the first image with high or low brightness.

For example, the terminal device may mark the positions of all the infrared hotspots. As shown in fig. 5, after an RGB image of a room a is collected by an RGB camera of a mobile phone, the image is displayed on a first interface (31 in fig. 5), at this time, if a user clicks the first interface 31, 4 infrared hotspots are displayed on the first interface, where a hotspot C (refer to fig. 5, the hotspot is located in a desk lamp) and a hotspot D (refer to fig. 5, the hotspot is located in a television) are two normal infrared hotspots, and the desk lamp and the television can emit heat, so that the hotspot C and the hotspot D can be eliminated to be identified by a frame; the hot spot a (referring to fig. 5, the hot spot is located on the wall surface) and the hot spot B (as shown in fig. 5, the hot spot is located on the wine bottle on the tea table) are target infrared hot spots and are identified by circles.

Optionally, in an embodiment of the present invention, the method further includes:

step A2: and the terminal equipment displays the third identification on M third positions of the second image.

And the M third positions are positions of the M infrared hot spots in the second image.

In an example, if the third mark is a pattern, the shape of the pattern may be any possible shape, such as a circle, a rectangle, a triangle, a diamond, a circle, or a polygon, which may be determined according to actual use requirements, and the embodiment of the present invention is not limited thereto. Further, the pattern may be displayed on the second image with high or low brightness.

For example, the terminal device may mark the position of the infrared hot spot in two split screens at the same time. As shown in fig. 6, after the user acquires an RGB image of the room a through the RGB camera of the mobile phone and acquires an infrared image of the room a at the same angle through the infrared camera of the mobile phone (the image is indicated as an infrared image by oblique lines in fig. 6), the RGB image is displayed on the interface of the first split screen (i.e., 31 in fig. 6), and the infrared image is displayed on the interface of the second split screen (i.e., 32 in fig. 6). At this time, the user clicks the first interface 31, and four infrared hot spots (the related description refers to the related description of fig. 5 above) are displayed on the first interface, and are identified by triangles on the second split-screen interface 32.

It should be noted that the first identifier, the second identifier, and the third identifier may be the same or different, and this is not limited in this embodiment of the present invention.

It should be noted that, the step a2 may be executed before the step 201, or may be executed after the step 201, and the present invention is not limited to this.

According to the method for determining the position of the infrared hot spot, provided by the embodiment of the invention, since the hidden camera (for example, a pinhole camera) emits heat when working, so as to generate the infrared spectrum, in the embodiment of the invention, the terminal device searches the positions of all suspicious hot spots (namely, the infrared hot spots) according to the second image (namely, the infrared image acquired by the infrared camera) after receiving the first input of the user under the condition that the first image (namely, the non-infrared image acquired by the non-infrared camera) is displayed on the first interface. Meanwhile, the first image and the second image are respectively images acquired by the non-infrared camera and the infrared camera aiming at the same shooting object, so that the position of each infrared hot spot in the second image is associated with the position of the infrared hot spot in the first image. Therefore, the terminal device can display the first identifier at the position of the target infrared hotspot (such as the hidden camera) on the first image to prompt the user of the position of the target infrared hotspot, so that the user can quickly lock the hidden camera and avoid privacy disclosure.

Optionally, the display module 402 is further configured to display a third identifier at M third positions of the second image; the M third positions are positions of the M infrared hot spots in the second image.

According to the terminal device provided by the embodiment of the invention, as the hidden camera (for example, a pinhole camera) emits heat when working, so as to generate the infrared spectrum, the terminal device in the embodiment of the invention searches the positions of all suspicious heat points (namely, infrared hot points) according to the second image (namely, the infrared image acquired by the infrared camera) after receiving the first input of the user under the condition that the first image (namely, the non-infrared image acquired by the non-infrared camera) is displayed on the first interface.
