It can be seen that, using this solution, the problem of different targets detected in a short time being assigned the same identifier can be avoided, and accordingly, the abnormality of processing the detection information of the target can be avoided.

[0055] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0056] The inventor of the present application has found through research that, when assigning identifications to detected targets, a number can be randomly assigned within a certain number range and used as the identification assigned to the target. When the target exits the tracking process, the number is released and put back into the candidate pool. When a new target appears, a number is randomly selected from the candidate pool and assigned to the new target.

[0057] However, this method may cause the same number to be repeatedly used in a short period of time, that is, the same number may be assigned to different targets in a short period of time, so that the number cannot be used to uniquely locate a target, that is, the function of distinguishing different targets based on the number cannot be realized. Correspondingly, the processing of the target detection information may be abnormal.

[0058] In order to solve the above problems, an embodiment of the present application provides an information processing method and device.

[0059] Exemplary Methods

[0060] See also Figure 1 , which is a flow chart of an information processing method provided in an embodiment of the present application. Figure 1 The method shown can be applied to a detection system including a detection device, wherein the detection device includes but is not limited to a radar.

[0061] Figure 1 The method shown includes the following S101-S102.

[0062] S101: In response to detecting a first target in a detection environment, a target identifier is provided for the first target according to a first candidate identifier that has been released and is included in an identifier candidate pool, wherein the identifier candidate pool includes the first candidate identifier and the time when the first candidate identifier has been released. If the time when the first candidate identifier has been released is greater than or equal to a preset time, the target identifier is the first candidate identifier. If the time when the first candidate identifier has been released is less than the preset time, the target identifier is a second candidate identifier that is calculated based on the first candidate identifier and is different from the first candidate identifier.

[0063] The detection device, such as a radar, can detect targets in its surrounding environment. The detection environment mentioned here may be the surrounding environment of the detection device. The embodiment of the present application does not specifically limit the first target, and the first target includes but is not limited to a person or an object.

[0064] In the embodiment of the present application, considering that the number of targets that the detection device can detect may be more than one, in order to distinguish different targets, an identifier can be assigned to the target after the target is detected, so as to distinguish different targets by using the identifier of the target, and accordingly, the candidate can also process the detection information of the target based on the identifier assigned to the target. Therefore, if the detection device detects a first target in the detection environment, the detection system can assign a target identifier to the first target in response to detecting the first target in the detection environment.

[0065] The identifiers mentioned in the embodiments of the present application include, but are not limited to, one or more of numbers, letters, and special characters. In a specific example, the identifier of the target may be, for example, the number of the identifier (i.e., corresponding to the aforementioned number). The number of the identifier may be, for example, a positive integer.

[0066] In order to avoid the same identifier being reused in a short period of time, in an embodiment of the present application, an identifier candidate pool may be preset, and the identifier candidate pool may include at least one candidate identifier that has been released and the time when each candidate identifier in the at least one candidate identifier has been released. The at least one candidate identifier includes at least the first candidate identifier.

[0067] The time when the candidate identification has been released mentioned here can be a specific time, for example, ** seconds, or a data refresh cycle of the detection device, for example, * data refresh cycle.

[0068] In the embodiment of the present application, a target identifier may be allocated to the first target according to the first candidate identifier that has been released.

[0069] In one example, if the time that the first candidate identifier has been released is greater than or equal to the preset time, it means that the first candidate identifier has been released for a long time, and accordingly, the first candidate identifier can be assigned to a new target at this time. Therefore, if the time that the first candidate identifier has been released is greater than or equal to the preset time, the target identifier can be the first candidate identifier, that is, the first candidate identifier can be assigned to the first target.

[0070] In another example, if the time that the first candidate identifier has been released is less than the aforementioned preset time, it means that the time that the first candidate identifier has been released is not long enough. If the first candidate identifier is assigned to a new target at this time, it may cause the same identifier (i.e., the first candidate identifier) ​​to be assigned to multiple objects in a short period of time. Therefore, in an embodiment of the present application, if the time that the first candidate identifier has been released is less than the aforementioned preset time, the first candidate identifier can be calculated accordingly to obtain a second candidate identifier different from the first candidate identifier, and the second candidate identifier is determined as the target identifier. In one example, the second candidate identifier is also not the identifier of other targets currently being processed.

[0071] The embodiment of the present application does not specifically limit the preset time, and the preset time can be determined according to actual conditions.

[0072] S102: Process the detection information of the first target based on the target identifier.

[0073] After assigning a target identifier to the first target, the detection information of the first target can be processed based on the target identifier. In one example, the correspondence between the target identifier and the detection information of the first target can be saved. Accordingly, the saved detection information of the first target can be extracted with the target identifier as an index to facilitate subsequent analysis and processing of the detection information of the first target. The embodiment of the present application does not specifically limit the specific implementation method for analyzing and processing the detection information of the first target. The analysis and processing of the detection information of the first target can be related to the application scenario corresponding to the detection system, and will not be described in detail here.

[0074] From the above description, it can be seen that when a target identifier is assigned to a first target using the solution of an embodiment of the present application, a candidate identifier is not randomly selected from the released candidate identifiers as the target identifier, but the target identifier is assigned to the first target based on the time when the released candidate identifiers were released, thereby avoiding the problem of different targets detected in a short period of time being assigned the same identifier. Accordingly, anomalies in processing the target's detection information can be avoided.

[0075] Next, the specific implementation of "assigning a target identifier to the first target according to the first candidate identifier included in the identifier candidate pool" is introduced when the time when the first candidate identifier is released is less than the preset time.

[0076] See also Figure 2 , which is a flow chart of a method for assigning a target identifier to a first target provided in an embodiment of the present application. Figure 2 The method shown includes the following S201-S202.

[0077] S201: Determine a first candidate identifier group to which the first candidate identifier belongs.

[0078] In an embodiment of the present application, the candidate pool of identifiers may include multiple candidate identifier groups, each of the multiple candidate identifier groups includes N candidate identifiers, and the N candidate identifiers in the multiple candidate identifier groups correspond one to one. In other words, for any candidate identifier in a candidate identifier group, each of the other candidate identifier groups has a candidate identifier that uniquely corresponds to the candidate identifier. For example:

[0079] The multiple candidate identification groups include candidate identification group 1 and candidate identification group 2. Candidate identification group 1 includes 80 candidate identifications, which correspond to numbers 1 to 80 respectively. Candidate identification group 2 also includes 80 candidate identifications, which correspond to numbers 81 to 160 respectively. Number 1 corresponds to number 81, number 2 corresponds to number 82, and so on. Candidate identification i in candidate identification group 1 corresponds to candidate identification i+80 in candidate identification group 2.

[0080] In an example, the identifier of the target may be the number of the target. In this case, the aforementioned identifier candidate pool may be a number candidate pool, and the number candidate pool may include N candidate numbers.

[0081] The embodiments of the present application do not specifically limit the value of N, as long as N is greater than the maximum number of targets that the detection device can detect simultaneously. In a specific example, in order to save storage space occupied by storing target identifiers, N can be equal to the maximum number of targets that the detection device can detect simultaneously.

[0082] In an example, the first candidate identifier may be compared with candidate identifiers in a plurality of candidate identifier groups to determine the candidate identifier group to which the first candidate identifier belongs.

[0083] In another example, each candidate identification group may have an identification, for example, each candidate identification group has a number. In this case, S201 may be implemented to determine the number of the first candidate identification group. Specifically, the first value may be determined based on the quotient of the first candidate identification and the aforementioned N. The first value is used to identify the first candidate identification group. In other words, the first value is the identification of the first candidate identification group.

[0084] In one example, the quotient of the first candidate identifier and N may be rounded down to obtain the first value. For example, if the first candidate identifier is 90 and N is 80, the first value is 1, that is, the identifier of the first candidate identifier group is 1. In another example, the quotient of the first candidate identifier and N may be rounded up to obtain the first value. For example, if the first candidate identifier is 90 and N is 80, the first value is 2, that is, the identifier of the first candidate identifier group is 2.

[0085] S202: Determine the second candidate identifier in the second candidate identifier group that corresponds to the first candidate identifier as the target identifier.

[0086] In one example, a candidate identifier group may be randomly selected from other candidate identifier groups except the first candidate identifier group as the second candidate identifier group, and the second candidate identifier in the second candidate identifier group corresponding to the first candidate identifier may be determined as the target identifier.

[0087] In another example, the next candidate identifier group of the first candidate identifier group may be determined as the second candidate identifier group, and the second candidate identifier in the second candidate identifier group corresponding to the first candidate identifier may be determined as the target identifier.

[0088] When the first candidate identification group is not the candidate identification group with the largest number among the multiple candidate identification groups, the next candidate identification group of the first candidate identification group may be a candidate identification group with a number that is 1 greater than that of the first candidate identification group.

[0089] When the first candidate identification group is the candidate identification group with the largest number among the multiple candidate identification groups, the next candidate identification group of the first candidate identification group may be the candidate identification group with the smallest number among the multiple candidate identification groups.

[0090] In one example, whether the first candidate identification group is the candidate identification group with the largest number among the plurality of candidate identification groups can be determined by comparing a first value and a second value. The second value is determined according to the quotient of the largest number in the candidate number pool and N. In one example, the quotient of the largest number and N can be rounded down to obtain the second value. In another example, the quotient of the largest number and N can be rounded up to obtain the second value.

[0091] In a specific example, if the first value is less than the second value, it is determined that the first candidate identifier group is not the candidate identifier group with the largest number among the multiple candidate identifier groups. At this time, the second candidate identifier can be determined from the candidate identifier group with the corresponding number (first value + 1). As mentioned above, a candidate identifier group includes N candidate identifiers. In a specific example, the first candidate identifier can be added to N to obtain the second candidate identifier.

[0092] In another specific example, if the first numerical value is equal to the second numerical value, it is determined that the first candidate identifier group is the candidate identifier group with the largest number among the multiple candidate identifier groups. At this time, the second candidate identifier can be determined from the candidate identifier group corresponding to the number 0. In a specific example, the first candidate identifier can be subtracted from the product of N and the second numerical value to obtain the second candidate identifier.

[0093] For example:

[0094] N is 80, and the maximum number in the candidate number pool is 255, then the second value is 3. The multiple candidate identification groups include candidate identification group 1, candidate identification group 2, and candidate identification group 3. Candidate identification group 1 includes 80 candidate identifications, corresponding to numbers 1 to 80 respectively, candidate identification group 2 also includes 80 candidate identifications, corresponding to numbers 81 to 160 respectively, and candidate identification group 3 includes 80 candidate identifications, corresponding to numbers 161 to 240 respectively. Number 1, number 81, and number 161 correspond to each other, number 2, number 82, and number 162 correspond to each other, and so on. Candidate identification i in candidate identification group 1 corresponds to candidate identification i+80 in candidate identification group 2, and candidate identification i+160 in candidate identification group 3.

[0095] Assuming that the first candidate identifier is 16, the first numerical value is 0, and the first numerical value is smaller than the second numerical value, it can be determined that the second candidate identifier is 16+80=96.

[0096] Assuming that the first candidate identifier is 254, the first numerical value is 3, and the first numerical value is equal to the second numerical value, then it can be determined that the second candidate identifier is: 254-80*3=14.

[0097] The embodiment of the present application does not specifically limit the first candidate identifier, and the first candidate identifier may be any candidate identifier among the candidate identifiers that have been released.

[0098] In one example, in order to use the released candidate identifiers as much as possible, instead of regenerating new candidate identifiers based on the released candidate identifiers, the released candidate identifiers can be sorted from large to small according to the time when the candidate identifiers have been released, and the candidate identifier with the highest sorting is determined as the first candidate identifier. In this scenario, the storage space occupied by storing the identifier of the target can be saved.

[0099] In one example, after determining the target identifier based on the first candidate identifier, the first candidate identifier and the time when the first candidate identifier has been released can be deleted from the identifier candidate pool. In this way, it is possible to avoid continuing to allocate an identifier to the second target based on the first candidate identifier when other targets, such as the second target, appear, and accordingly avoid different targets being allocated the same identifier within a short period of time.

[0100] In one example, if the first target exits the detection process, the target identifier and the time when the target identifier has been released can be recorded in the identifier candidate pool, so that when a new target appears, an identifier can be assigned to the new target based on the target identifier. The first target exits the detection process when the first target disappears from the detection environment or when the first target disappears from the detection environment and the detection information processing of the first target is completed.

[0101] The detection information of the first target mentioned in the embodiments of the present application includes but is not limited to measurement information such as radial distance, radial Doppler velocity, azimuth, and altitude.

[0102] The above introduces the information processing method provided in the embodiment of the present application. Next, taking the target identification as the target number as an example, combined with a specific scenario, the solution provided in the embodiment of the present application is introduced.

[0103] 1. Based on the size of the storage space for storing numbers, set the range of numbers [ID min ,ID max ], assuming ID min =1, ID max = 255. In addition, it is determined that the maximum number of targets that the detection device can detect simultaneously is N = 80.

[0104] ID-based max and N, it can be determined that the second value = 3.

[0105] 2. Determine that the aforementioned multiple candidate identification groups include candidate identification group 1, candidate identification group 2, and candidate identification group 3. Wherein:

[0106] Candidate identification group 1 includes 80 candidate identifications, which are numbered 1 to 80 respectively;

[0107] Candidate identification group 2 also includes 80 candidate identifications, corresponding to numbers 81 to 160;

[0108] Candidate identifier group 3 includes 80 candidate identifiers, corresponding to numbers 161 to 240 respectively.

[0109] Number 1, number 81 and number 161 correspond to each other, and candidate identification i in candidate identification group 1 corresponds to candidate identification i+80 in candidate identification group 2 and candidate identification i+160 in candidate identification group 3.

[0110] 3. Perform statistical management on the time when the released numbers have been released. That is, record the released numbers and the time when the numbers have been released. Also, set the time interval M for re-activation of the same number, where M corresponds to the aforementioned preset time and the value of M is 10.

[0111] The M mentioned here may be the data refresh period of the detection device. Specifically, since the data refresh period of the detection device is 50 milliseconds, in order to achieve the requirement that the activation interval of the same number is not less than 0.5s, the value of M is set to 10.

[0112] 4. Sort the released numbers and the time clocks at which they were released in descending order of clock. The sorting results are shown in Table 1 below:

[0113] Table 1

[0114] serial number clock 16 30 14 9 251 4 …… ……

[0115] In the current detection cycle, three targets are detected (all three targets can correspond to the first target mentioned above), namely target 1, target 2 and target 3. Target identifiers are assigned to target 1, target 2 and target 3 in turn.

[0116] For target 1, since the time when number 16 has been released is greater than 10, number 16 can be assigned to target 1, and number 16 and the time when number 16 has been released are deleted.

[0117] For target 2, since the time when number 14 has been released is less than 10, the first value can be calculated. The calculated first value is equal to 0 (that is, less than the second value 3). At this time, 14+80=94 can be assigned to target 2, and number 14 and the time when number 14 has been released can be deleted.

[0118] For target 3, since the time when number 251 has been released is less than 10, the first value can be calculated. The calculated first value is equal to 3 (that is, equal to the second value 3). At this time, 251-3*80=11 can be assigned to target 2, and number 251 and the time when number 251 has been released can be deleted.
