[0068] Please refer to Figure 2 , Figure 2 Another flowchart of a vehicle navigation method of a parking lot provided by the embodiments of the present application.

[0069] According to the license plate recognition information, the method further comprises the following steps before the step of S200: matching in the preset multiple groups of navigation marks to obtain the vehicle navigation mark.

[0070] S201: According to the on-site environment information of the parking lot, a plurality of groups of navigation marks are obtained, and the navigation marks include one or more of the forward mark, the left turn mark, the right turn mark, the U-turn mark and the parking mark.

[0071] According to the on-site environment information of the parking lot, a plurality of groups of navigation marks with high distinguishability (preset multiple groups of navigation marks) are preselected, which can improve the distinguishability of the vehicle navigation mark when the approaching vehicle is navigated, and can bind the navigation mark groups with high distinguishability to the vehicle respectively, thereby avoiding the approaching vehicles from cutting in or recognizing wrong navigation marks when they meet, and improving the user experience.

[0072] According to the navigation route information, the approaching vehicle is navigated, and the vehicle navigation mark is projected to the front of the approaching vehicle.

[0073] S410: According to the navigation route information, one or more of the forward mark, the left turn mark, the right turn mark, the U-turn mark and the parking mark are projected in turn in front of the approaching vehicle.

[0074] According to the navigation route information, one or more of the forward mark, the left turn mark, the right turn mark, the U-turn mark and the parking mark are projected in turn in the process of the approaching vehicle moving, thereby realizing the whole navigation of the approaching vehicle.

[0075] Exemplarily, after the step S400 of projecting the vehicle navigation mark to the front of the approaching vehicle according to the navigation route information, the method further comprises:

[0076] S420: acquiring video monitoring data at the parking lot intersection;

[0077] S430: acquiring current license plate recognition information of the current driving vehicle at the intersection according to the video monitoring data;

[0078] S440: acquiring approaching time information, current idle parking space number information, current navigation route information and current navigation state information corresponding to the current license plate recognition information according to the current license plate recognition information.

[0079] Exemplarily, at the parking lot intersection, there may be a situation that multiple approaching vehicles queue or intersect; at this time, the license plate number (current license plate recognition information) of the first vehicle driving at the intersection is acquired through the video monitoring data at the parking lot intersection, and navigation is performed for the vehicle; thereby, the navigation of multiple approaching vehicles is realized in sequence, and confusion caused by simultaneous display of navigation information at the intersection is avoided.

[0080] Exemplarily, after the step S440 of acquiring approaching time information, current idle parking space number information, current navigation route information and current navigation state information corresponding to the current license plate recognition information according to the license plate recognition information, the method further comprises:

[0081] S450: when it is determined that the parking space is occupied according to the current idle parking space number information, re-allocating an idle parking space and updating the current navigation route information;

[0082] S460: when it is determined that the vehicle deviates according to the current navigation route information, updating the current navigation route information.

[0083] Exemplarily, in the case that the idle parking space is occupied or the vehicle deviates, the idle parking space is re-allocated to the approaching vehicle, and the current navigation route information is updated, thereby realizing dynamic navigation.

[0084] Exemplarily, after the step S400 of projecting the vehicle navigation mark to the front of the approaching vehicle according to the navigation route information, the method further comprises:

[0085] S470: generating voice broadcast information according to the license plate recognition information and the vehicle navigation mark.

[0086] Exemplarily, the voice broadcast information is generated according to the features of the license plate recognition information and the vehicle navigation mark, and corresponding voice prompts are played, thereby further improving the user experience. For example, the voice broadcast information can be "Guangdong B88888, please follow the green navigation mark".

[0087] In some implementation scenarios, in combination with Figure 1 and Figure 2 The specific process of the vehicle navigation method of the parking lot provided by the embodiments of the present application is as follows:

[0088] Step 1. According to the on-site environment of the parking lot, a plurality of groups of navigation marks with high discrimination are preselected, wherein each group of navigation marks includes: forward, left turn, right turn, U-turn, and parking.

[0089] Step 2. When the vehicle enters, the license plate recognition method is used to obtain license plate recognition information (license plate number).

[0090] Step 3. A group of navigation marks that is not currently occupied is selected from the plurality of groups of navigation marks, and is bound with the license plate recognition information, and the group of navigation marks is set as being occupied.

[0091] Step 4. The vehicle is assigned a free parking space according to the existing free parking space state of the parking lot, and navigation route information is planned according to the free parking space. The acquisition of the free parking space state, the assignment of the free parking space, and the planning of the navigation path according to the free parking space can be performed according to the existing technical solutions, and the present application does not make any limitation.

[0092] Step 5. The forward mark in the group of navigation marks is projected in front of the vehicle, and a voice prompt is played according to the license plate recognition information and the characteristics of the vehicle navigation mark, for example, “Please follow the green navigation mark, Guangdong B88888”.

[0093] Step 6. The video monitoring screen of the monitoring camera installed at each intersection is obtained, and the license plate number of the first vehicle driving to the intersection on each channel is identified using the license plate recognition algorithm.

[0094] Step 7. The entry time, free parking space number, navigation path, and navigation state corresponding to the license plate number are queried.

[0095] Step 8. Whether the vehicle is an entry vehicle or a vehicle about to exit is determined according to the entry time and the navigation state. For example, if the entry time is less than 30 minutes and the navigation state is in progress, it is determined that the vehicle is an entry vehicle.

[0096] Step 9. For the entry vehicle, the current occupancy of the free parking space is queried according to the free parking space number. When the parking space is currently occupied, a free parking space is reassigned and a navigation path is replanned.

[0097] Step 10. For the entry vehicle, whether the vehicle has deviated is determined according to the navigation path and the current position of the monitoring camera. If the vehicle has deviated, the navigation path is replanned.

[0098] Step 11, for the approaching vehicle, according to its navigation path, monitoring the current position of the camera, calculating the direction the vehicle needs to travel at the current intersection, such as forward, left turn, right turn, U-turn, etc.

[0099] Step 12, for the approaching vehicle, according to the navigation identification group corresponding to its license plate number, calling the projection device installed directly above the intersection, projecting the navigation identification corresponding to the travel direction at the intersection. For example, for the vehicle of Guangdong B88888 which needs to go straight in the navigation path, a green forward identification is projected. Preferably, when there are two or more vehicles meeting at the intersection, the navigation identification corresponding to the vehicle that arrives first should be projected according to the order of arrival; after the vehicle passes through the intersection, the navigation identification of other vehicles should be projected in sequence.

[0100] Step 13, when the vehicle navigation ends, setting the navigation identification group state corresponding to it as unoccupied, setting its navigation state as ended, and setting its occupied parking space as occupied.

[0101] In some implementation scenarios, according to the on-site environment of the parking lot, the step of pre-selecting multiple groups of navigation identifications with high distinguishability includes the following examples:

[0102] Step 1, pre-designing multiple groups of navigation identifications, respectively projecting them to each intersection, and collecting images from multiple different angles;

[0103] Step 2, classifying the collected images according to the features of the navigation identification groups, requiring the classification accuracy to be greater than a preset threshold; when the classification accuracy does not meet the preset threshold, removing the group of navigation identifications with the highest error rate from the images and recalculating the accuracy; the classification method includes manual classification, using a pre-trained image classification model for classification, unsupervised image classification (such as kmeans clustering algorithm), etc., which are not limited in any way;

[0104] Step 3, classifying the collected images according to the signal categories of the navigation identifications, requiring the classification accuracy to be greater than a preset threshold; when the classification accuracy does not meet the preset threshold, removing the group of navigation identifications with the highest error rate from the images and recalculating the accuracy; the classification method includes manual classification, using a pre-trained image classification model for classification, unsupervised image classification (such as kmeans clustering algorithm), etc., which are not limited in any way;

[0105] Step 4, after the above steps, the remaining navigation identification groups are the multiple groups of navigation identifications with high distinguishability.
