It is understood that, in practical situations, the above application scenarios are only examples, and the number of the smart driving vehicles, the moving targets, the environmental sensors, and the servers that can be included in the above application scenarios may also be any number specified, which is not limited in this application.
Further, referring to fig. 3, based on the application scenario, an embodiment of the present application provides a method for parking a valet, where the method may be applied to the intelligent driving vehicle 101 and/or the server 104, and the intelligent driving vehicle 101 is taken as an example for description, and the method specifically includes:
s301: and responding to the automatic cruising of the intelligent driving vehicle, and acquiring the target displacement information of each moving target in the parking environment of the intelligent driving vehicle.
Specifically, the valet parking system may automatically instruct the intelligent driving vehicle to enter into automatic cruising when the intelligent driving vehicle is at a starting position for valet parking, for example, when the intelligent driving vehicle is at an entrance of a parking lot.
For example, the user may manually instruct the smart driving vehicle to enter into the automatic cruise mode, for example, by means of an on-board display screen, a terminal client, an on-board remote controller, and the like.
For example, when the smart driving vehicle navigates to a parking position indicated by a certain instruction, if the parking position does not meet a preset parking condition, the current position of the smart driving vehicle may also be used as the start position of the valet parking, so that when the valet parking system is at the start position, the smart driving vehicle is instructed to enter into the auto cruise.
Further, responding to the automatic cruising of the intelligent driving vehicle, and acquiring target displacement information of each moving target in the parking environment of the intelligent driving vehicle; specifically, the moving objects may be any obstacle in the parking environment, such as a person, a vehicle, an animal, and the like, and in the embodiment of the present application, for each moving object existing in the environment, the object displacement information of each moving object may be obtained by a sensing sensor mounted on the smart driving vehicle and/or an environment sensor configured in the parking environment.
Specifically, in an alternative embodiment, when obtaining the target displacement information of each moving target through a perception sensor mounted on the intelligent driving vehicle and/or an environment sensor configured in a parking environment, the following steps may be performed:
s3011: acquiring respective perception information of at least one obstacle in a parking environment, wherein each perception information at least comprises: a perceived image acquired for an obstacle.
Specifically, when the intelligent driving vehicle automatically navigates, the sensing sensor mounted inside the vehicle or the environmental sensor mounted in the parking environment where the intelligent driving vehicle is located can be used for detecting each obstacle object with the corresponding entity outline in the current parking environment in real time, and obtaining the respective sensing information of each obstacle object.
For example, in an alternative embodiment, the intelligent driving vehicle may acquire image data of a front position or a peripheral position of the intelligent driving vehicle in real time through a visual sensor mounted inside the intelligent driving vehicle during an automatic cruising process of the intelligent driving vehicle, and when acquiring a perception image of a certain obstacle, the perception image is used as perception information of the obstacle.
For example, in another optional embodiment, the intelligent driving vehicle may further receive, in real time, a perception image issued by the server to the intelligent driving vehicle through a communication connection with the server corresponding to the current parking environment; specifically, the perception image may be acquired by an environment sensor mounted in the current parking environment, and the perception image may include at least one obstacle object in the current parking environment, so that when the smart driving vehicle receives the perception image, the perception image may be used as target perception data of a corresponding moving target.
S3012: and respectively carrying out feature extraction on the obtained perception information to obtain respective perception features of at least one obstacle object.
Specifically, in an actual situation, obstacle objects in a parking environment where the vehicle is located may be fixed, such as roadblocks, fences, and the like, in order to improve analysis efficiency of a target predicted trajectory, in the embodiment of the present application, for respective perception information of each obstacle object in the current parking environment, feature extraction may be performed on the obtained respective perception information, so that each moving target to be analyzed is selected from the extracted respective perception features.
For example, in an alternative embodiment, feature extraction may be performed on the perception information respectively acquired by each obstacle through a preset Convolutional Neural Network (CNN), so that, based on the perception features respectively extracted by each obstacle, a corresponding moving object, such as a "person", "a vehicle", and the like, meeting a preset condition is selected from the perception features.
S3013: and respectively taking each obstacle with corresponding perception characteristics meeting preset conditions in at least one obstacle as a moving target in the parking environment, tracking each moving target, and obtaining target displacement information of each moving target.
Specifically, based on the extracted sensing features, the obstacle objects in the parking environment, the corresponding sensing features of which meet preset conditions, are used as moving targets to be analyzed, and the sensing sensors carried by the vehicle and/or the environment sensors arranged in the parking environment are/is adopted to track the determined moving targets, so that the target displacement information of each moving target is obtained.
For example, in this embodiment of the application, based on the extracted sensing features, the corresponding sensing features in the parking environment may be characterized as obstacle objects of a "person" or a "vehicle" as moving targets to be analyzed, and target displacement information of each moving target may be obtained through a detection and positioning device such as a laser radar mounted in the vehicle and/or the parking environment, where the target displacement information may include a moving direction, a moving distance, a moving speed, and the like, which is not limited in this application.
It is worth further explaining that, in an actual situation, data fusion can be performed on the collected corresponding perception data of different perception sensors carried in the vehicle and/or the parking environment, so as to obtain more accurate target displacement information for the detected moving target.
For example, in an actual application scenario, a visual sensor mounted in a vehicle and/or a parking environment may be used to perform feature extraction and target tracking on a detected moving target, so as to obtain first displacement data of the moving target, such as a target type and a moving distance, and a laser radar mounted in the vehicle and/or the parking environment is used to perform time synchronization on point cloud data and an acquired image corresponding to a current parking environment, and then second displacement data of the moving target, such as a moving speed and a moving direction, is obtained based on a determined target type and coordinate transformation of the laser radar, in this embodiment of the present application, data fusion may be performed on the first displacement data and the second displacement data respectively acquired by the visual sensor and the laser radar, so that while data accuracy of corresponding sensing data acquired by each sensing sensor is ensured, the accuracy of target displacement information obtained by fusion is further improved.

Furthermore, in order to ensure the driving safety of the intelligent driving vehicle in the process of passenger-assistant parking, the target prediction tracks of the moving targets in the current parking environment are analyzed based on the obtained displacement information of the targets.
In an optional embodiment, based on the obtained displacement information of each target, a movement path of each moving target in the current parking environment may be predicted through a movement rule and a movement model set corresponding to the parking environment, and then a target prediction track corresponding to each moving target is determined according to a prediction result, specifically, the method includes the following steps:
s3021: and acquiring an environmental road condition corresponding to the parking environment.
