Description

Technical Field

[0001] This invention relates to the field of artificial intelligence technology, and in particular to an infrared interactive sensing system and its control method. Background Technology

[0002] With the development of technology, traditional user interaction methods can no longer meet user needs. Infrared interactive sensing is a popular interaction method in today's market. When performing infrared interactive sensing, many response roles are often used. Each role represents a device, and each response role may have multiple different response actions based on different sound effects triggered by events. Interactive sensing is completed through the coordination of multiple roles.

[0003] If control is achieved through a central control module, firstly, the information exchange efficiency is poor, and secondly, the connection between multiple roles and the central control module will require many signal lines, affecting the aesthetics of the interactive scene. In addition, the infrared sensing methods on the market today are relatively simple, often triggering based on whether the intensity of the acquired infrared signal exceeds a threshold, which is too monotonous and cannot meet the user's needs. Summary of the Invention

[0004] The purpose of this invention is to at least address one of the shortcomings of the prior art by providing an infrared interactive sensing system and its control method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution.

[0006] Specifically, an infrared interactive sensing control method is proposed, including the following:

[0007] Multiple trigger events based on infrared sensing results are preset. According to the needs of each trigger event, the corresponding roles in the infrared interactive sensing system are established into communication groups to obtain the same number of communication groups as the number of trigger events.

[0008] Pre-set trigger conditions and corresponding response methods for each role in the communication group;

[0009] Obtain infrared sensing information;

[0010] The infrared sensing results are obtained by analyzing the relevant information from the infrared sensing.

[0011] Based on the infrared sensing results, infrared interactive sensing control is performed according to preset trigger events.

[0012] Furthermore, specifically, the infrared sensing-related information includes infrared signal datasets collected by multiple infrared sensor groups at different times.

[0013] Furthermore, specifically, the infrared sensing results are obtained by analyzing the relevant information from the infrared sensing, including:

[0014] Step 310: Obtain the infrared signal dataset at the current time T;

[0015] Step 320: Determine whether multiple users exist based on the infrared signal dataset at the current time T.

[0016] Step 3211: If there is only one user, calculate the distance between the user and each infrared sensor based on the data recorded by each infrared sensor in the infrared signal dataset, and obtain the distance dataset D = {d1, d2, ..., dn} at the current moment. Considered as the distance factor for the current user,

[0017] Step 3212: Obtain the infrared signal datasets for the previous time T-1 and the next time T+1 respectively. Similarly, calculate the distance dataset D1 for the previous time and its corresponding distance factor σ1, and the distance dataset D2 for the next time and its corresponding distance factor σ2.

[0018] Step 3213: If σ1 < σ < σ2, then the user is judged to be in a far away state; if σ1 > σ > σ2, then the user is judged to be in a near state; if σ1 < σ > σ2, then the user is judged to be in a lingering state; if σ1 > σ < σ2, then the user is judged to be in a departing state.

[0019] Step 3221: If there are multiple users, calculate the multiple data points collected by each infrared sensor at the current moment, and then calculate the corresponding multiple distances. The average of these multiple distances is considered as the distance between an equivalent user and its corresponding infrared sensor. Based on this, the distance dataset D and distance factor σ of the equivalent user are calculated using the method described in step 3211.

[0020] Step 3222: Obtain the infrared signal datasets for the previous time T-1 and the next time T+1 respectively. Similarly, calculate the distance dataset D1 and distance factor σ1 corresponding to the equivalent user at the previous time, and the distance dataset D2 and distance factor σ2 at the next time.

[0021] Step 3223: If σ1 < σ < σ2, then the equivalent user is determined to be in a far away state; if σ1 > σ > σ2, then the equivalent user is determined to be in a near state; if σ1 < σ > σ2, then the equivalent user is determined to be in a lingering state; if σ1 > σ < σ2, then the equivalent user is determined to be in a departing state.

[0022] Step 330: Use the corresponding state judgment result as the infrared sensing result.

[0023] Furthermore, specifically, the corresponding distance is calculated based on the data collected by each infrared sensor, including:

[0024] When the infrared transmitter in the infrared sensor emits light and it is used by the user, the reflected light is fed back to the CCD detector. At this time, we can know the angle α of the emitted light relative to the infrared transmitter, the offset distance L of the reflected light relative to the CCD detector, and the focal length f of the lens. The distance X between the infrared transmitter and the CCD detector is fixed. Based on the triangulation principle, the distance between the user and the infrared sensor is calculated.

[0025] Furthermore, specifically,

[0026] The preset trigger conditions for each role in the communication group include self-triggered conditions based on the timeline and non-self-triggered conditions based on the responses of other roles;

[0027] Each trigger event is initiated by a preset sound effect recognition result, and the corresponding roles in the communication group respond one by one in a preset order.

[0028] During the response, each character in the communication group will report their completion status in the communication group after completing the response. Other characters will wait in the communication group for a situation that matches their own preset trigger conditions, and will respond accordingly when a situation that matches their preset trigger conditions is found.

[0029] The present invention also proposes an infrared interactive sensing system, comprising:

[0030] The communication group division module is used to preset multiple trigger events based on infrared sensing results, and to establish communication groups for the corresponding roles in the infrared interactive sensing system according to the needs of each trigger event, so as to obtain the same number of communication groups as the number of trigger events.

[0031] The preset module is used to preset the trigger conditions and corresponding response methods for each role in the communication group;

[0032] Infrared sensing information acquisition module, used to acquire infrared sensing-related information;

[0033] The data analysis module is used to analyze infrared sensing information to obtain infrared sensing results;

[0034] The response module is used to perform infrared interactive sensing control based on the infrared sensing results and according to preset trigger events.

[0035] Furthermore, specifically, the infrared sensing information acquisition module is an infrared sensor group, which includes multiple infrared sensors, each of which can independently acquire infrared data to determine the distance to multiple targets.

[0036] Furthermore, specifically, when calculating distance, the infrared sensor includes,

[0037] When the infrared transmitter in the infrared sensor emits light and it is used by the user, the reflected light is fed back to the CCD detector. At this time, we can know the angle α of the emitted light relative to the infrared transmitter, the offset distance L of the reflected light relative to the CCD detector, and the focal length f of the lens. The distance X between the infrared transmitter and the CCD detector is fixed. Based on the triangulation principle, the distance between the user and the infrared sensor is calculated.

[0038] The present invention also proposes a computer-readable storage medium storing a computer program that, when executed by a processor, implements the steps of any of the above-described infrared interactive sensing methods.

[0039] The beneficial effects of this invention are as follows:

[0040] This invention divides the corresponding roles in the entire infrared interactive sensing system into multiple communication groups, the same number as the number of trigger events, and each role triggers independently. In this way, once a trigger event occurs, the required roles will autonomously respond according to the preset communication group and preset trigger conditions, improving interaction efficiency. In addition, by collecting data from multiple infrared sensors and then performing data analysis to determine the user's status, and responding and interacting accordingly based on the user's status, the user experience can be improved.

[0053] Step 310: Obtain the infrared signal dataset at the current time T;

[0054] Step 320: Determine whether multiple users exist based on the infrared signal dataset at the current time T.

[0055] Step 3211: If there is only one user, calculate the distance between the user and each infrared sensor based on the data recorded by each infrared sensor in the infrared signal dataset, and obtain the distance dataset D = {d1, d2, ..., dn} at the current moment. Considered as the distance factor for the current user,

[0056] Step 3212: Obtain the infrared signal datasets for the previous time T-1 and the next time T+1 respectively. Similarly, calculate the distance dataset D1 for the previous time and its corresponding distance factor σ1, and the distance dataset D2 for the next time and its corresponding distance factor σ2.

[0057] Step 3213: If σ1 < σ < σ2, then the user is judged to be in a far away state; if σ1 > σ > σ2, then the user is judged to be in a near state; if σ1 < σ > σ2, then the user is judged to be in a lingering state; if σ1 > σ < σ2, then the user is judged to be in a departing state.

[0058] Step 3221: If there are multiple users, calculate the multiple data points collected by each infrared sensor at the current moment, and then calculate the corresponding multiple distances. The average of these multiple distances is considered as the distance between an equivalent user and its corresponding infrared sensor. Based on this, the distance dataset D and distance factor σ of the equivalent user are calculated using the method described in step 3211.

[0059] Step 3222: Obtain the infrared signal datasets for the previous time T-1 and the next time T+1 respectively. Similarly, calculate the distance dataset D1 and distance factor σ1 corresponding to the equivalent user at the previous time, and the distance dataset D2 and distance factor σ2 at the next time.

[0060] Step 3223: If σ1 < σ < σ2, then the equivalent user is determined to be in a far away state; if σ1 > σ > σ2, then the equivalent user is determined to be in a near state; if σ1 < σ > σ2, then the equivalent user is determined to be in a lingering state; if σ1 > σ < σ2, then the equivalent user is determined to be in a departing state.

[0062] In this preferred embodiment, the user's state can be determined in the above manner, and a response can be made according to the user's state in a preset response manner.

[0063] In a preferred embodiment of the present invention, specifically, the corresponding distance is calculated based on the data collected by each infrared sensor, including:

[0064] When the infrared transmitter in the infrared sensor emits light and it is used by the user, the reflected light is fed back to the CCD detector. At this time, we can know the angle α of the emitted light relative to the infrared transmitter, the offset distance L of the reflected light relative to the CCD detector, and the focal length f of the lens. The distance X between the infrared transmitter and the CCD detector is fixed. Based on the triangulation principle, the distance between the user and the infrared sensor is calculated.

Other characters will wait in the communication group for a situation that matches their own preset trigger conditions, and will respond accordingly when a situation that matches their preset trigger conditions is found.

[0069] In this embodiment 1, it is assumed that there are N roles, such as light 1, light 2, speaker 1, speaker 2, ..., N. Light 1, light 2, and speaker 1 are taken as a communication group. Speaker 1 has a time-based trigger condition, that is, when the clock reaches a preset value, speaker 1 will automatically broadcast. In addition, there is an event triggered by infrared recognition results, which first makes light 2 flash, then speaker 1 responds, and finally light 1 illuminates. That is, when light 2 flashes, it will send a flashing response information to the communication group. After speaker 1 receives it, it will respond, and after speaker 1 responds, light 1 will illuminate.
