[0063] In the prior art, when parking guidance is performed in a parking lot, vehicles are guided to specific vacant parking spaces. However, some vehicles do not drive to the corresponding vacant parking spaces according to the parking guidance route, thereby affecting the parking guidance of subsequent vehicles, reducing the accuracy of the overall parking guidance of the parking lot, and since there are no vacant parking spaces for subsequent vehicles to park, it may also cause road congestion in the parking lot. The disclosed embodiment provides a technical solution, which is for the case where the parking lot includes at least one lane, by obtaining vehicle traffic data and parking space vacancy data of each lane in the parking lot, and then generating a heat map of the parking lot according to the vehicle traffic data and parking space vacancy data of each lane in the parking lot, the heat map includes the heat value of each lane in the parking lot, and through the above-mentioned heat map of the parking lot, the status of each lane in the parking lot can be fully displayed, and finally the parking guidance information is generated according to the heat map of the parking lot. In the technical solution disclosed in the present invention, since the heat map includes the heat value of each lane, it can fully display the status of each lane, and then the above-mentioned parking guidance information can also more accurately guide the vehicle to the appropriate lane, so that the guided vehicle can find a suitable parking space on the lane while avoiding congestion, making the guidance process more convenient and improving the accuracy and reliability of parking guidance.

[0064] In the embodiment of the present disclosure, the technical solution for parking guidance in the parking lot can be specifically referred to Figure 1 shown. Figure 1 A flow chart of a parking guidance method for a parking lot provided by an embodiment of the present disclosure is provided. The method can be executed on an electronic device, including but not limited to a server, a local computer, etc. Figure 1 As shown, the method comprises the following steps:

[0065] Step 101: Obtain vehicle traffic data and parking space vacancy data for each lane in the parking lot;

[0066] Specifically, the parking lot in the embodiment of the present disclosure can be as follows Figure 2 As shown, the parking lot includes four lanes, namely road1, road2, road3 and road4. Each lane can be used for vehicles to pass, and parking spaces are set on one side or both sides of the lane. In this step, the vehicle traffic data and parking space vacancy data of the above four lanes are obtained.

[0067] Lane traffic data includes data on vehicles currently passing through, as well as data on vehicles entering and exiting parking spaces in the lane, because the above three data will affect the traffic conditions of the lane. Therefore, the above vehicle traffic data for each lane in the parking lot may include:

[0068] At least one of the data of vehicles parking in, vehicles parking out, and vehicles passing through is obtained for each lane in the parking lot.

[0069] In the disclosed embodiment, a lane monitoring camera can be installed above the lane to identify the behavior of vehicles on the lane based on computer vision to determine whether the vehicle is parking in a vacant parking space in the lane or whether it is parking out of a parking space in the lane. i When a vehicle is detected parking in or out of a parking space, the vehicle parking system records and reports the data of the vehicle being parked. in and the data of the vehicle being parked out n ou .

[0070] In the same way as above, vehicles passing through the lane can also be identified and counted, and the data of vehicles passing through can be recorded. d And report it.

[0071] For parking space availability data, a parking space monitoring system can be used, such as a parking space monitoring camera installed in a parking lot, to monitor the empty or full status of all parking spaces in the parking lot. i , record its empty and full status S i , if the parking space is vacant, then S i =1, otherwise S i =0.

[0072] For a lane R i All parking spaces p on the network, calculate their sum S = ∑S i , that is, the parking space vacancy data of the lane is obtained.

[0073] Step 102: Generate a thermal map of the parking lot based on the vehicle traffic data and parking space vacancy data of each lane in the parking lot, wherein the thermal map of the parking lot includes a thermal value of each lane in the parking lot;

[0074] In this step, for each lane R in the parking lot, a calculation model of the heat map is constructed, in which the lane traffic and vacant parking spaces are considered from the perspectives of lane traffic and parking. Specifically, the parking heat value of each lane is generated based on the parking space vacancy data of each lane in the parking lot, and the traffic heat value of each lane is generated based on the vehicle traffic data of each lane in the parking lot.

[0075] For example, the thermal value of each lane Ri is H(R i )=H p +H d . Among them, H p is the parking thermal value, H d is the normal thermal value.

[0076] The parking thermal value can be calculated by the following formula: H p =S / count(p), that is, the ratio of the free parking space data to the total parking space data on the lane, the value range is [0,1], H p The value of is close to 1, which means that the more free parking spaces there are in the lane, the easier it is to park in the lane.

[0077] The passing thermal value can be calculated by the following formula: H d =(W×(n in +n out )+n d ) / n p , where W is the impact coefficient of parking on traffic, which can be set according to actual needs, for example, it can be set to 3, n p The maximum number of vehicles that the lane can accommodate under normal traffic conditions.

[0078] After obtaining the parking thermal value and the passing thermal value of each lane in the above manner, the thermal value of each lane can be generated according to the parking thermal value and the passing thermal value. In some cases, the sum of the parking thermal value and the passing thermal value of each lane can be used as the thermal value of the lane, or, further, taking into full consideration the connectivity between the lanes in the parking lot, and considering that the passing state of the subsequent lanes will also affect the passing of the current lane, in the embodiment of the present disclosure, after obtaining the sum of the parking thermal value and the passing thermal value of each lane, it is used as the initial thermal value of the current lane, and then the influence of the thermal value of the subsequent lane associated with the current lane on the current lane is considered to further calculate the thermal value of the current lane. The specific method can be:

[0079] The initial thermal value of each lane is obtained according to the sum of the parking thermal value of each lane and the passing thermal value; then the thermal value of the current lane is obtained according to the initial thermal value of the current lane and the initial thermal value of the subsequent lane associated with the current lane.

[0080] In the specific implementation process, according to the lanes included in the parking lot, the lanes can be used as nodes V of the graph, and the lane nodes that can be reached later can be connected through edges E through the lane nodes associated with the intersection to construct a directed connection graph G of the lanes in the parking lot. i , find all the successor nodes of this node in graph G, that is, from node V i The nodes that can be directly reached through an edge in the lane directed link graph are counted as set V s , then all the subsequent lanes of the current lane are found. s All nodes in V sj , update Vi The thermal value of the node Hn(V i )=H(V i )+∑w×H(V sj ), where H(V i ) is the initial thermal value of the current lane, H(V sj ) is the initial thermal value of the subsequent lane, and w is the adjacent edge weight, which can be set according to the actual situation. For example, w can be set to 0.1. For different subsequent lanes, a unified adjacent edge weight can be set, or different adjacent edge weights can be set respectively.

[0081] Figure 3 Based on Figure 2 The parking lot shown here constructs a directed connection graph of lanes, where lane road1 corresponds to Figure 3 Node V in 1 , lane road2 corresponds to Figure 3 Node V in 2 , lane road3 corresponds Figure 3 Node V in 3 , lane road4 corresponds Figure 3 Node V in 4 At this time, for lane road1, its subsequent lanes include lane road2 and lane road3. When calculating the thermal value of lane road1, the thermal value of lane road1 can be obtained according to the following formula:

[0082] Hn(V 1 )=H(V 1 )+w 2 ×H(V 2 )+w 3 ×H(V 3 )

[0083] Among them, w 2 and w 3 Represent the weight values ​​of lane 2 and lane 3 respectively, H(V 2 ) and H(V 3 ) represent the initial thermal values ​​of lane road2 and lane road3 respectively.

[0084] Step 103: Generate parking guidance information according to the heat map of the parking lot.

[0085] In the above step 102, a heat map of the parking lot is obtained, and the heat value of each lane is recorded in the heat map. Thus, the display color of each lane can be generated according to the heat value of each lane, and then the parking guidance information can be generated according to the display color of each lane. That is, at each intersection, the selectable lanes with different heat values in the parking lot can be displayed in different colors. For example, the lanes with high heat values are displayed in red, and the lanes with low heat values are displayed in green. At this time, the driver can choose to drive in the lanes displayed in green, which is not easy to be blocked and it is easy to find an idle parking space.

[0086] In some embodiments, after calculating the heat value Hn of each lane according to step 102, normalization processing can be performed on the heat values of all lanes in the parking lot. For example, take the maximum value Hmax among all the Hn values of all lanes, with 0 as the minimum value, and normalize all the values in Hn to the interval [0,1]. That is, for each lane Ri, its normalized heat value H N (i) = Hn(i) / Hmax.

[0087] In the embodiments of the present disclosure, in the parking lot, guiding signs can be set at the entrance and each intersection to display part or all of the heat map of the current parking lot. Combining with the traffic direction of the lanes, the passable lanes at each intersection are marked in red and green colors. When the normalized H N value is 0, the color is red; when the value is 1, the color is green. When the heat value is other intermediate values, the color transitions from red to green. Among them, red can be understood as a prohibited or non-recommended lane. For example, for a one-way lane in the parking lot, the non-passable direction can be set to red, while green is a passable lane. When there are multiple passable lanes at an intersection driving in different directions, they can be distinguished by a color gradient from green to red according to the heat value. The greener it is, the smoother the traffic in the lane in that direction, or the more idle parking spaces there are, and it is more recommended that the driver drive the vehicle in that direction for parking.

[0088] In the embodiments of the present disclosure, the situation of idle parking spaces or the traffic conditions of the lanes may change at any time. At this time, the heat map can be updated according to the above changes. That is, when the parking heat value and / or the traffic heat value of the lanes in the parking lot change, the heat map is updated. The specific situation can be as Figure 4 shown, including the following steps 201, 202 and 203. Among them, step 201 is triggered when the idle data of the parking spaces in at least one lane changes, and step 202 is triggered when a preset time interval is reached. The order of the triggering times of the two is determined according to the actual situation, and the embodiments of the present disclosure do not limit it. After at least one of step 201 and step 203 is triggered, step 203 can be executed. The specific content of each step is as follows:

[0089] Step 201: If the parking space occupancy data of at least one lane changes, update the parking heat value according to the changed parking space occupancy data to obtain the updated parking heat value of the lane.

[0090] Specifically, as described in the above embodiments, a parking space monitoring system can be used to monitor the occupancy status of parking spaces. In this step, when it is monitored that the number of available parking spaces changes, the updated parking heat value of the lane is recalculated.

[0091] Step 202: If a preset time interval is reached, re-obtain the updated vehicle traffic data of at least one lane in the parking lot, and obtain the updated traffic heat value of the lane according to the updated vehicle traffic data.

[0092] That is, it can be set to update and calculate the traffic heat value H of the lane every Δt time. d where Δt can be adjusted in combination with the number of vehicles in the current parking lot. The more vehicles there are, the faster the update frequency, and the update period can be set to 5s.

[0093] Step 203: Generate the heat value of each lane according to the updated parking heat value and / or the updated traffic heat value.

[0094] By recalculating the heat value of each lane, it is possible to make timely feedback on the occupancy of parking spaces and traffic changes in the parking lot, and obtain a heat map that can more accurately reflect the actual situation of the parking lot. Using this heat map for parking guidance can also improve the real-time and accuracy of parking guidance.
