Background
With the increase of age, the cognitive power and the memory of the old people are obviously degraded, which often causes the old people to go out and lose the condition of returning.

According to the embodiment of the disclosure, the searching instructions are sent to the plurality of mobile second terminals according to the searching information from the first terminal, and the searching results are determined according to the feedback results of the plurality of mobile second terminals, so that the defects of low density and small coverage of the camera in the related searching scheme can be overcome, the searching range is expanded, and the searching efficiency is effectively improved.
The steps of the embodiment shown in FIG. 2 will be described in detail below.
In step S202, first search information from the first terminal is received.
The information interaction method of the embodiment of the present disclosure may be used for searching for a plurality of targets, which may include at least human beings, other animals (e.g., pets), intelligent vehicles, buildings, mobile places of business, etc., and the intelligent vehicles may include, for example, automobiles, non-automobiles, various electric intelligent vehicles, etc., to which the present disclosure is not particularly limited.
In the disclosed embodiment, the first search information may include at least a search object image, a missing time period, a missing position range, and search object description information.
The image to be searched may be a photograph, a video, or other image information. The source of the search object image includes, but is not limited to, the search requester provides, the drive test fixed camera record, the search result of the previous search action, and the like.
The missing time period may be, for example, a time range in which the search target is last monitored so as to determine the second terminal participating in the search; the missing position range may be represented by a plurality of coordinate points, a range surrounded by the plurality of coordinate points, or a center point + radius, for example, to analyze an area where the search target is most likely to appear, so as to determine the second terminal participating in the search. When the search target is a building, the missing time period may not be included.
When the search object is a human, the search object description information may include, for example, gender, age, height, weight, wearing, other special features, and the like; when the search object is an animal, the search object description information may include, for example, species, shoulder height, fur color, and other special features; when the search object is an intelligent vehicle, the object description information may include, for example, the type, color, brand model, number plate (if any), and other special features of the intelligent vehicle; when the search object is a building or a business place (e.g., a mobile vending cart), the object description information may include, for example, length, width, height, color, facade decoration features, and other special features. The disclosure is not described one by one, and those skilled in the art can set the detailed content of the first search information according to the actual situation, and the disclosure is not limited thereto.
In step S204, second search information is sent to a plurality of second terminals according to the first search information, where the second terminals are mobile devices provided with an image acquisition device and an image analysis device.
In the system 100, the server cluster B may determine a second terminal participating in the search according to the first search information, and further send second search information for identifying a search instruction to the second terminal.
When the search object is a moving object, the characteristics of the second terminal participating in the search can be determined according to the missing time period and the missing position range in the first search information. The second terminals present in the location range during the time period can be determined from the missing time period and the missing location range, and a search can be performed using these second terminals, for example, by sending second search information to all vehicles present in the location range during the time period. It is understood that, in the embodiment of the present disclosure, the search using the second terminal is not limited to real-time shooting, and the second terminal may also participate in the search by retrieving the stored image, where the second search information may include a missing time period, so that the second terminal determines the range of retrieving the stored image.
In addition, the search position range can be determined according to the missing time period, the missing position range, the action mode of the search object and the action speed of the search object, and second search information can be sent to the second terminal currently in the search position range. The action mode (walking or riding the intelligent vehicle) and the action speed of the search object can be provided by the first terminal through the first search information.
When the search object is a fixed target, the search position range can be determined according to the missing position range, and second search information is sent to the second terminal currently in the search position range. As with the missing position range, the search position range may be represented by a plurality of coordinate points, a range surrounded by a plurality of coordinate points, or a center point + a radius. It is understood that the number of the search position ranges may be plural.
The image acquisition device of the second terminal may be, for example, a camera, and the image analysis device may be, for example, a processor. In order to ensure the searching efficiency, the second terminal participating in the searching may be a mobile device in which the image acquisition device can acquire images at any time. The device can be searched by utilizing intelligent vehicles, intelligent glasses and other devices which can often acquire images at any time; mobile devices such as smartphones that are often stored, smartwatches that are easily covered by clothing, and the like, cannot acquire images at any time, and may be used only for auxiliary searching or not for searching.
In the embodiment of the present disclosure, the second search information at least includes a search information identifier, a search object image, a search object description information, a third search information image matching degree threshold, and the like.
The second search information may carry a search information identifier to indicate that the second terminal completes the search task. In addition, the images to be searched provided by the first search information can be screened, and the images which are helpful for searching are added into the second search information. The criteria for image filtering include, but are not limited to, resolution, sharpness, ratio of search target in the image, sharpness of search target, image integrity of search target, etc. The image screening may be performed by a tool capable of pattern recognition, such as a neural network model, and the disclosure is not limited thereto.
Information that is helpful for the second terminal to search can be determined according to the description information of the search object in the first search information and added into the second search information. The search object description information in the second search information may be the same as or different from the search object description information in the first search information. The search object description information in the second search information may include information such as the outline size and surface features of the search object.
After the second terminal receives the second search information, the second terminal can shoot or call the stored information in real time through the image acquisition device and the image analysis device to complete a search task and determine a plurality of search results. For example, the image in the real-time captured or stored information may be matched with the image provided by the second search information to obtain a plurality of matching results.
In order to avoid that the second terminal reports the search result frequently to influence the search judgment efficiency, a third search information image matching degree threshold value can be set, that is, the second terminal is controlled to generate the third search information according to the local image for reporting only when the matching degree of the local image and the image provided by the second search information exceeds the third search information image matching degree threshold value, so that the information processing efficiency is improved.
In the embodiment of the present disclosure, the third search information at least includes the captured image and the matching probability between the captured image and the image in the second search information, so as to further filter the search result.
In step S206, third search information sent by at least one of the second terminals according to the second search information is received, and a search result is returned to the first terminal.
In the embodiment of the present disclosure, a search result screening threshold may be preset to improve the search result determination efficiency. For example, one or more pieces of third search information that are most favorable for determining the search result may be determined according to whether the image definition is greater than the threshold, or the matching degree is greater than the threshold, or the third search information has a specific feature (e.g., a human face), among the plurality of pieces of third search information fed back by the plurality of second terminals, and these selected third search information may be fed back to the first terminal as the search result.
