Detailed Description
It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Referring to fig. 1, which is a flowchart illustrating steps of a first embodiment of an infrared positioning method according to the present invention, as shown in fig. 1, the infrared positioning method includes the following steps:
s100, acquiring a template image of a target object, wherein the template image is a visible light image of the target object;
in an embodiment, a template image of the target object is obtained, where the template image is a visible light image of the target object. In this step, a terminal acquires a template image, wherein the template image is a visible light image of a target object shot by an image pickup device, and the image pickup device uploads the shot visible light image of the target object to the terminal, wherein the image pickup device and the terminal can be connected in a wired or wireless manner, i.e. the visible light image shot by the image pickup device can be transmitted to the terminal in a wired or wireless manner. Or, the terminal may send an information acquisition instruction to the image capturing apparatus, and after receiving the information acquisition instruction, the image capturing apparatus captures a visible light image of the target object and sends the visible light image to the terminal, and the terminal receives the visible light image of the image capturing apparatus and pre-stores the template image as the target object.
In an embodiment, the target object may be a text object, that is, when the image capturing device captures a visible image of the target object, the text object is turned to a text page to be captured and placed under a lens of the image capturing device, and the image capturing device may be connected to the terminal and triggered by the matched application software, so that the lens above the image capturing device captures the text page to be captured, so as to capture a visible light image of the text object. Of course, the photographing apparatus in this embodiment may also manually photograph the visible light image of the text object, which is not limited herein.
In an embodiment, the target object may be another object, such as a picture object, which is not limited herein. While the above-mentioned photographing device includes, but is not limited to, all-pass color cameras, etc., of course, in other embodiments, any photographing device may be used to photograph the visible light image of the target object, which is not limited herein.
In an embodiment, when the target object is a text object, that is, when the photographed text page is photographed, the photographed text page should be in a static state, so that the selected template image avoids image deviation generated due to vibration of the photographing device or shake of the text page to be photographed, thereby ensuring quality of the template image.
It can be understood that the content in the template image corresponds to the content in the database preset by the target object.
S200, when the target object receives the infrared signal emitted by the infrared light source module, acquiring an infrared image acquired by the infrared camera module;
in one embodiment, an infrared signal is generated by an infrared light source module and emitted onto a target object. When the target object receives the infrared signal emitted by the infrared light source module, the infrared image acquired by the infrared camera module is acquired.
In one embodiment, the position of the infrared signal is captured by an infrared camera module and an infrared image is formed. The infrared camera module adopts an infrared camera, and can shoot infrared images of infrared signals through the infrared camera.
In an embodiment, the shooting range of the infrared camera is consistent with the shooting range of the shooting device in S100, and of course, when the shooting range of the infrared camera is inconsistent with the shooting range of the shooting device, the shooting range of the infrared camera may be kept consistent with the shooting device by adjusting the angle of view of the infrared camera.
In an embodiment, when the target object is a text object, that is, the text object is turned to a photographed text page and placed under the infrared camera, and then the infrared signal is directly emitted to the photographed text, at this time, the infrared camera may be connected to the terminal and triggered by the matched application software to photograph an infrared image of the infrared signal. Of course, the photographing apparatus in this embodiment may also adopt a manual photographing of an infrared image of an infrared signal, which is not limited herein. The infrared camera and the terminal can be connected in a wired or wireless mode, namely, an infrared image shot by the infrared camera can be transmitted to the terminal in a wired or wireless mode.
In an embodiment, the infrared camera is a camera sensitive to infrared signals, that is, an infrared image captured by the infrared camera has a marker, and the marker is a position of the infrared signals in the target object.
In an embodiment, the infrared light source module is an infrared emitting tube, and the infrared emitting tube is configured to emit an infrared signal, where a wavelength of the infrared signal is 940nm. Of course, in other embodiments, other specific infrared sources may be used according to specific needs, without limitation.
S300, comparing the infrared image with the template image to confirm the positioning position of the infrared signal on the target object;
in an embodiment, the infrared image in S200 is compared with the template image in S100, that is, the position of the infrared signal in the infrared image on the template image may be obtained, so as to confirm the positioning position of the infrared signal on the template image, that is, the positioning position of the infrared signal on the target object may be confirmed.
In an embodiment, since the template image photographed in S100 corresponds to the content of the pre-stored database of the target object, that is, after the position of the infrared signal on the template image is obtained, that is, the positioning process of the infrared signal is finished at this time, the computer invokes the TTS speech engine or the speech packet with the computer to read the text recognized by the OCR recognition engine according to the positioning position of the infrared signal, so as to complete the operation of infrared click-to-read positioning.
In an embodiment of the present invention, the infrared positioning method includes acquiring a template image of a target object, where the template image is a visible light image of the target object; when the target object receives the infrared signal emitted by the infrared light source module, an infrared image acquired by the infrared camera module is acquired, and the infrared image is compared with the template image to confirm the positioning position of the infrared signal on the target object. Therefore, the technical scheme provided by the embodiment can accurately position the target object to the position on the target object through the infrared signal so as to accurately position the content of the position to be identified by the user, and the user experience is improved.
Based on the first embodiment, the present invention also provides a second embodiment of the infrared positioning method, and fig. 2 is a flowchart illustrating steps of the second embodiment of the infrared positioning method.
As shown in fig. 2, the step S200 further includes:
s210, acquiring an infrared shooting range of the infrared shooting module, and detecting whether the infrared signal exists in the infrared shooting range;
in an embodiment, in the step S200, when the target object receives the infrared signal emitted by the infrared light source module, the infrared image of the infrared signal is acquired, that is, when the infrared image of the infrared signal is captured, the terminal connected with the infrared image capturing module firstly acquires the infrared capturing range of the infrared image capturing module, where the infrared capturing range of the infrared image capturing module is consistent with the capturing range of the capturing device, so that the range of the target object in the infrared image is consistent with the range of the target object in the template image, and the accuracy of the comparison result between the infrared image and the template image can be improved.
In an embodiment, before the infrared camera module collects the infrared image of the infrared signal, it is required to detect whether the infrared signal exists in the infrared shooting range. For example, when the target object is a text object, a region having text on the text object is taken as a photographing range of the photographing apparatus, that is, the region is also an infrared photographing range, and at this time, whether an infrared signal exists in the region, that is, whether a landing point of the infrared signal has text on the text object is detected. Of course, in other embodiments, when the target object is an image object, the area of the entire image may be taken as the shooting range of the shooting device, that is, the infrared shooting range, or the middle portion of the image object may be taken as the shooting range of the shooting device, which is not limited herein.
S220, if the infrared signals exist in the infrared shooting range, acquiring infrared images acquired by the infrared shooting module;
in an embodiment, if an infrared signal is detected to exist in the infrared shooting range, an infrared image acquired by the infrared camera module is acquired, and the specific content refers to the description of S100 in the first embodiment and is not repeated herein.
In an embodiment, when the shooting object is a text object, that is, when an infrared signal of a shot text page is shot, the shot text page should be in a static state, so that the acquired infrared image is prevented from causing deviation of a shooting range between the infrared image and a template image due to vibration of shooting equipment or shake of the text page to be shot, and accuracy of confirming the position of the infrared signal is ensured.
In an embodiment, if no infrared signal exists in the infrared shooting range, the infrared shooting module does not execute the acquired infrared image. For example, in the step S210, when the target object is assumed to be a text object, the area with the text on the text object is taken as the shooting range of the shooting device, that is, the area is also the infrared shooting range, and at this time, when the drop point of the infrared signal is on the text object and is located outside the area with the text, that is, the infrared signal is not determined to be within the infrared shooting range.
In an embodiment of the present invention, the above infrared positioning method further includes obtaining an infrared shooting range of the infrared camera module, and detecting whether the infrared signal exists in the infrared shooting range; and if the infrared signal exists in the infrared shooting range, acquiring an infrared image acquired by the infrared shooting module.

S222, if the signal intensity is larger than a preset value, acquiring an infrared image acquired by the infrared camera module;
in one embodiment, the step of acquiring the infrared image of the infrared signal is performed if the signal strength is greater than a predetermined value. The preset value is set according to the specific infrared positioning requirement in the embodiment, and optionally, the preset value is 0.033W. Of course, in other embodiments, the preset value may be set to other values according to specific requirements, which is not limited herein.
In an embodiment, when the signal intensity is greater than 0.033W, an infrared image acquired by the infrared camera module is acquired, and the specific content refers to the description of S100 in the first embodiment and is not repeated herein.
In an embodiment, if the signal strength is less than or equal to the preset value, the infrared signal may not be the infrared signal emitted by the infrared generating device, that is, the signal strength may be an interference signal of other devices, that is, when the signal strength is less than or equal to 0.033W, no processing is performed.
In an embodiment of the present invention, the above infrared positioning method further includes acquiring signal intensity of the infrared signal if the infrared signal exists in the infrared shooting range, and acquiring an infrared image acquired by the infrared camera module if the signal intensity is greater than a preset value. Thus, when the signal intensity of the infrared signal is larger than a preset value, the interference of other signals can be filtered out.
Based on the first embodiment, the present invention also provides a fourth embodiment of the infrared positioning method, and fig. 4 is a flowchart illustrating steps of the fourth embodiment of the infrared positioning method.
As shown in fig. 4, in step S300, the above infrared positioning method further includes:

in an embodiment, the shooting ranges of the infrared image and the template image are consistent, so that the template image and the infrared image are completely overlapped, namely, when the infrared image is compared with the template image, the infrared image and the template image are overlapped together, and the coordinates of the infrared signal in the infrared image in a plane rectangular coordinate system can be confirmed. That is, after comparing the coordinates of the template image with the infrared signal in the infrared image, the coordinate value corresponding to the infrared signal on the template image is obtained.
S330, confirming the positioning position of the infrared signal on the target object according to the coordinate value;
in one embodiment, the location of the infrared signal on the target object may be confirmed by the coordinate value corresponding to the infrared signal confirmed in step S220 on the template image.
In one embodiment, when the positioning position of the infrared signal on the target object is obtained, the computer may call a TTS speech engine or a speech packet in the computer to read the text recognized by the OCR recognition engine according to the positioning position of the infrared signal, so as to complete the operation of infrared click-to-read positioning.

In an embodiment, when the infrared signal moves from one point to another point of the target object, the infrared image of the infrared signal needs to be captured again by the infrared imaging module, that is, in this embodiment, the infrared imaging module may capture the infrared image of the infrared signal at regular time, for example, the infrared signal may move to the next position every 30s, that is, the infrared imaging module captures the infrared image of the infrared signal every 30s, and the positioning position of the infrared signal is confirmed according to the coordinate ratio of the infrared image and the template image. Here, the positioning position of the above-mentioned infrared signal includes a plurality of.
