In the above description, the skilled person will be able to design instructions in accordance with the disclosed solution. How the instructions control the operation of the processor is well known in the art and will not be described in detail herein.
< method examples >
The embodiment of the disclosure provides a method for identifying a lost object behavior of a person on a vehicle, as shown in fig. 2, the method comprises the following steps:
s201: in-vehicle condition data of a vehicle is acquired at a first time.
In the embodiment of the present disclosure, since the present invention is intended to identify whether the person in the vehicle has a behavior of losing objects outside the vehicle by comparing the object set carried by the person in the vehicle immediately before the vehicle gets on the vehicle and the object set carried by the person in the vehicle at the current time, in the process of identifying whether the person in the vehicle has the behavior of losing objects outside the vehicle, it is first necessary to determine the object carried by the person in the vehicle at the current time.
Further, in the embodiment of the present disclosure, in order to determine the items carried by the persons in the vehicle at the present time, the in-vehicle condition data of the vehicle needs to be acquired at the first time.
Here, the first time point refers to the current time point, that is, the acquired in-vehicle condition data is in-vehicle condition data of the vehicle at the current time point.
In addition, the in-vehicle condition data can be image data acquired through an in-vehicle camera, and can reflect the condition of articles carried by people on the vehicle.
S202: and determining the current article set corresponding to the personnel on the vehicle according to the in-vehicle condition data.
Further, since the in-vehicle condition data is image data acquired by the in-vehicle camera, after the in-vehicle condition data of the vehicle is acquired, the embodiment of the disclosure may perform image recognition on the in-vehicle condition data acquired by the in-vehicle camera through a pre-created image recognition model, so as to recognize the current item set corresponding to the on-vehicle person.
It should be noted that, in practical applications, articles discarded outside the window by the vehicle occupant are generally paper articles, bottle articles, plastic articles and cloth articles, so that the embodiments of the present disclosure can simulate an actual riding situation in the process of creating a sample image set of an image recognition model, obtain an in-vehicle image without paper articles, bottle articles, plastic articles and cloth articles, and an in-vehicle image with at least one of paper articles, bottle articles, plastic articles and cloth articles, create the sample image set according to the obtained in-vehicle image, and then train the image recognition model according to the sample image set.
Of course, the articles discarded outside the vehicle window by the vehicle occupant are not only paper articles, bottle articles, plastic articles and cloth articles, but also other various articles, the more the types of the articles contained in the sample image are, the higher the accuracy of identifying whether the vehicle occupant has the behavior of losing the articles outside the vehicle is, and the specific identification of which articles can be determined according to the actual situation.
It should be noted that, in order to distinguish the item set carried by the vehicle occupant immediately when the vehicle occupant gets into the vehicle from the item set carried by the vehicle occupant at the current time, in the embodiment of the present disclosure, the item set carried by the vehicle occupant immediately when the vehicle occupant gets into the vehicle is defined as the original item set, and the item set carried by the vehicle occupant at the current time is defined as the current item set.
Current collections of items include items carried by personnel onboard the vehicle, such as backpacks, water bottles, and the like.
S203: and identifying whether the personnel on the vehicle has the behavior of losing objects outside the vehicle according to the current object set and the pre-acquired original object set.
Furthermore, after the current article set corresponding to the vehicle personnel is determined, whether the vehicle personnel has the behavior of losing the object outside the vehicle can be identified according to the current article set and the pre-acquired original article set.
It should be noted that, because the present invention is intended to identify whether the vehicle occupant has a behavior of losing objects outside the vehicle by comparing the object set carried by the vehicle occupant immediately when the vehicle occupant gets into the vehicle with the object set carried by the vehicle occupant at the present time, in the embodiment of the present disclosure, whether the vehicle occupant has a behavior of losing objects outside the vehicle may specifically be as follows:
judging whether the current article set is consistent with the original article set; under the condition that the current article set is consistent with the original article set, identifying that the person on the vehicle does not have a behavior of losing objects outside the vehicle; and under the condition that the current item set is inconsistent with the original item set, identifying that the person on the vehicle has the behavior of losing the object outside the vehicle.
For example, assume that the pre-acquired original set of items includes: knapsack and mineral water bottle, the current collection of articles of determining includes: and the backpack judges that the current object set is inconsistent with the original object set, and identifies that the person on the vehicle has the behavior of losing objects outside the vehicle.
In addition, since the original article set is an article carried by a person in the vehicle when the person gets on the vehicle, in the embodiment of the present disclosure, the obtaining of the original article set may specifically be as follows:
monitoring whether the on-board personnel exist in the vehicle or not, acquiring the on-board condition data of the vehicle under the condition that the on-board personnel exist in the vehicle, and determining and acquiring an original article set corresponding to the on-board personnel according to the on-board condition data.
It should be noted that the detection of the presence of the on-board person in the vehicle indicates that the on-board person has just got on the vehicle.
By the method, the current article set corresponding to the on-board personnel at present is compared with the original article set corresponding to the on-board personnel when the on-board personnel just get on the vehicle, whether the on-board personnel have the behavior of losing articles outside the vehicle can be effectively identified, and the phenomenon that the on-board personnel lose articles outside the vehicle at will when taking the vehicle to move out is greatly reduced.
In practical applications, there is a possibility that a person on a vehicle does not lose objects outside a window, but some objects in an original object set are placed in a pocket or a backpack, so that the current object set is inconsistent with the original object set, and therefore, in order to improve the accuracy of identifying the object losing behavior of the person on the vehicle, the embodiment of the disclosure provides the following two implementation modes for identifying whether the person on the vehicle has the behavior of losing objects outside the vehicle under the condition that the current object set is inconsistent with the original object set.
The first embodiment: when the vehicle personnel lose objects outside the vehicle window, the hands of the vehicle personnel tend to extend out of the vehicle window, so that the position relation between the hands of the vehicle personnel and the vehicle window of the vehicle at the third moment is obtained under the condition that the current object set is inconsistent with the original object set; under the condition that the position relation is that the hands of the on-board personnel are positioned outside the window of the vehicle, identifying that the on-board personnel have a behavior of losing objects outside the vehicle; and under the condition that the hand of the person on the vehicle is positioned in the window of the vehicle in the position relation, identifying that the person on the vehicle does not have a behavior of losing objects outside the vehicle.
It should be noted that when it is determined that the current item set is inconsistent with the original item set, it is determined that a certain item disappears in the original item set at the moment, and if the vehicle occupant has a behavior of losing an item, the hand of the vehicle occupant tends to stick out of the window before the first time, so that the third time is earlier than the first time, the third time may be a time before the first time, or may be a time before the first time, N is an integer greater than 1, the larger N is, the farther the third time is from the first time is, the lower the accuracy rate of identifying whether the vehicle occupant has a behavior of losing an item outside the vehicle is, and conversely, the smaller N is, the closer the third time is from the first time is, the higher the accuracy rate of identifying whether the vehicle occupant has a behavior of losing an item outside the vehicle is.
The second embodiment: after the person on the vehicle loses objects outside the window, corresponding objects exist in the vehicle exterior identification, so under the condition that the current object set is inconsistent with the original object set, vehicle exterior condition data of the vehicle are obtained at a second moment, wherein the first moment is earlier than the second moment; judging whether the goods outside the vehicle exist or not according to the vehicle exterior condition data; identifying that the person on the vehicle has a behavior of losing objects outside the vehicle when the objects outside the vehicle exist; and under the condition that no goods outside the vehicle exist, identifying that the person on the vehicle does not have the behavior of losing the goods outside the vehicle.
It should be noted that, if the on-board person has a lost behavior, the discarded object may appear outside the vehicle only after the first time, and therefore the first time is earlier than the second time, that is, only after the on-board person is recognized to have the behavior of losing the object outside the vehicle at the first time, the vehicle exterior condition data of the vehicle need to be acquired at the second time, and based on the vehicle exterior condition data, whether the object outside the vehicle exists outside the vehicle is determined, so as to recognize that the on-board person has the behavior of losing the object outside the vehicle according to the object outside the vehicle.
It should be noted that the second time may be a time subsequent to the first time, or may be a time N subsequent to the first time, where N is an integer greater than 1, and the larger N indicates that the second time is farther from the first time and the lower the accuracy of identifying whether the on-vehicle person has a behavior toward the object lost outside the vehicle, and conversely, the smaller N indicates that the second time is closer to the first time and the higher the accuracy of identifying whether the on-vehicle person has a behavior toward the object lost outside the vehicle.
Further, even if it is determined that an object outside the vehicle exists, the object outside the vehicle may be thrown out by a pedestrian or another vehicle outside the vehicle and is not lost by a vehicle occupant outside the vehicle, and therefore, in order to improve the accuracy of the behavior of identifying the lost object of the vehicle occupant, the embodiments of the present disclosure provide the following three embodiments of identifying whether the vehicle occupant has the behavior of losing the object outside the vehicle on the basis of determining that the object outside the vehicle exists.
The first embodiment: determining a difference item between the current item set and the original item set in the case that an off-board item exists outside the vehicle; judging whether the difference object is consistent with the object outside the vehicle; identifying that the on-board person has a behavior of losing objects outside the vehicle if the difference object is consistent with the off-board object; and under the condition that the difference object is inconsistent with the object outside the vehicle, identifying that the person on the vehicle does not have a behavior of losing the object outside the vehicle.
The second embodiment: under the condition that the goods outside the vehicle exist, judging whether the time difference between the second moment and the first moment is lower than a preset threshold value or not; under the condition that the time difference is lower than a preset threshold value, identifying that the person on the vehicle has a behavior of losing objects outside the vehicle; and under the condition that the time difference is not lower than a preset threshold value, identifying that the person on the vehicle does not have a behavior of losing objects outside the vehicle.
Here, it should be noted that the time difference between the second time and the first time can reflect the possibility that the vehicle-exterior article is discarded by the vehicle occupant, and the smaller the time difference, the smaller the possibility that the vehicle-exterior article is discarded by the vehicle occupant, whereas the larger the time difference, the greater the possibility that the vehicle-exterior article is discarded by the vehicle occupant, and the time difference lower than a certain probability can directly confirm that the vehicle-exterior article is not discarded by the vehicle occupant, so that it is necessary to set a threshold value to determine which interval time difference can indicate that the vehicle-exterior article is directly related to the vehicle occupant.
Third embodiment: under the condition that an article outside the vehicle exists, acquiring the window state of the vehicle within a specific time period, wherein the specific time period is a time period from the first time to the second time; identifying that the person on the vehicle has a behavior of losing objects outside the vehicle when the vehicle window state comprises an open state; and under the condition that the window state does not contain an opening state, identifying that the person on the vehicle does not have a behavior of losing objects outside the vehicle.
It should be noted that, since the vehicle occupant wants to lose an object outside the vehicle, the time when the window of the vehicle is in the open state is between the first time and the second time, and therefore, in the embodiment of the present disclosure, the specific time period is a time period between the first time and the second time.
It should be noted that the above three embodiments may be used alone or in combination, that is, at least two of the first, second, and third embodiments may be used in combination, and the combined use may improve the accuracy of identifying whether the vehicle occupant has the behavior of losing the object outside the vehicle.
In the embodiment of the disclosure, in order to further reduce the phenomenon that the person on the vehicle loses objects outside the vehicle at will when the person on the vehicle moves out, after the person on the vehicle is identified to have the behavior of losing objects outside the vehicle by the above method, the person on the vehicle is prompted to have the behavior of losing objects through the window at present, so that the person on the vehicle can develop the habit of losing objects through the window at will.
In the disclosed embodiment, at least one of the following three items can be executed to prompt the vehicle occupant that the vehicle window lost behavior exists currently.
The first item: and warning the object loss behavior of personnel on the vehicle through the vehicle-mounted vision equipment of the vehicle.
