[0016] The following description of exemplary embodiments of the present disclosure is made in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding. These details should be considered as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0017] To evaluate the quality of a location's positioning data, the data can be presented in a data list on the client's browser. However, presenting positioning data in a data list makes it difficult to intuitively understand the specific details of the positioning data, which in turn affects the efficiency and accuracy of positioning data quality assessment.

[0018] To this end, embodiments of the present disclosure propose a high-precision map data display solution. Scene parameters are determined based on scene configuration information. The scene parameters are used to determine the visualization parameters of at least one anchor point on the map. Camera parameters are determined based on view configuration information. The camera parameters are used to determine the display view angle of the at least one anchor point. A rendering operation is performed using the scene parameters and camera parameters so that the at least one anchor point is visually displayed at its respective display position within the display view angle. The display position of each anchor point is determined based on its location data.

[0019] The above solution realizes the visualization of positioning data, which facilitates intuitive understanding of the specific situation of positioning data, thereby improving the efficiency and accuracy of positioning data quality assessment.

[0020] Figure 1 The present invention schematically illustrates an exemplary system architecture to which the method and apparatus for displaying high-precision map data can be applied according to an embodiment of the present disclosure.

[0021] It should be noted that Figure 1 The examples shown are merely examples of system architectures to which the embodiments of the present disclosure may be applied, to help those skilled in the art understand the technical content of the present disclosure, but do not mean that the embodiments of the present disclosure may not be used in other devices, systems, environments or scenarios.

[0022] like Figure 1 As shown, the system architecture 100 according to this embodiment may include clients 101, 102, 103, a network 104, and a server 105. The network 104 is used to provide a medium for communication links between the clients 101, 102, 103 and the server 105. The network 104 may include various connection types, such as wired and / or wireless communication links.

Clients 101, 102, and 103 may be various electronic devices with display screens that support web browsing, including but not limited to smartphones, tablet computers, laptop computers, and desktop computers.

[0024] For example, client 101 may be configured with a browser. Client 101 may determine scene parameters based on the scene configuration information. The scene parameters are used to determine the visualization parameters of at least one anchor point on the map. Camera parameters are determined based on the view configuration information. The camera parameters are used to determine the display view angle of the at least one anchor point. A rendering operation is performed using the scene parameters and camera parameters so that the at least one anchor point is visually displayed at its respective display position under the display view angle. The display position of each anchor point is determined based on the location data of the anchor point.

[0025] The client 101 generates a data generation request when determining that the display colors of at least one anchor point include a first display color, which is a display color corresponding to the abnormal anchor point.

[0026] The client 101 sends a data generation request to the server 105, so that the server 105 regenerates the positioning data of at least one positioning point based on the data generation rule in response to receiving the data generation request from the client 101, and obtains new positioning data of at least one positioning point.

[0027] The client 101 visually displays the at least one anchor point at its respective new display position in response to receiving the new positioning data of the at least one anchor point from the server 105. The new display position of each anchor point is determined based on the new positioning data of the anchor point.

[0028] Server 105 can be any type of server that provides various services. For example, server 105 can be a cloud server. A cloud server is a host product in the cloud computing service system that solves the management difficulties and poor business scalability of traditional physical hosts and VPS (Virtual Private Server) services.

[0041] According to embodiments of the present disclosure, a positioning point may refer to a point on a map. The map may include a high-precision map. Positioning data may refer to location data. The location data may be determined based on point cloud data.

[0042] According to an embodiment of the present disclosure, a client browser may generate a data acquisition request. The data acquisition request may include at least one data identifier. The client browser may send the data acquisition request to a server, so that the server, in response to receiving the data acquisition request from the client browser, may parse the data acquisition request to obtain the at least one data identifier. Positioning data for each anchor point corresponding to each of the at least one data identifier may be determined. The client browser, in response to receiving the positioning data for each of the at least one anchor point from the server, may receive the positioning data.

[0043] According to embodiments of the present disclosure, a client can create a scene, create a camera, determine scene parameters for the scene based on scene configuration information, and determine camera parameters for the camera based on camera configuration information. Data can be exchanged between the client and the server based on a data interface.

[0044] According to an embodiment of the present disclosure, after determining scene parameters and camera parameters, a rendering operation can be performed using the scene parameters and camera parameters to visually display each anchor point at its display position under a determined display perspective. The display position of the anchor point can be determined based on the positioning data of the anchor point.

[0045] According to an embodiment of the present disclosure, scene parameters are determined based on scene configuration information. The scene parameters are used to determine the visualization parameters of at least one location point on the map. Camera parameters are determined based on the perspective configuration information to determine the display perspective of the at least one location point. A rendering operation is performed using the scene parameters and camera parameters so that the at least one location point is visually displayed at its respective display position under the display perspective. This achieves a visual display of positioning data, facilitating an intuitive understanding of the specifics of the positioning data, thereby improving the efficiency and accuracy of positioning data quality assessment.

[0046] According to an embodiment of the present disclosure, the above-mentioned high-precision map data display method may also include the following operations.

[0047] If it is determined that the display colors of at least one anchor point include a first display color, a data generation request is generated. The first display color is the display color corresponding to the abnormal anchor point. The data generation request is sent to a server, so that the server, in response to receiving the data generation request from the client, regenerates the positioning data of the at least one anchor point based on a data generation rule to obtain new positioning data for the at least one anchor point. In response to receiving the new positioning data for the at least one anchor point from the server, the at least one anchor point is visually displayed at its new display position, wherein the new display position of each anchor point is determined based on the new positioning data for the anchor point.

[0048] According to embodiments of the present disclosure, anchor point types may include normal anchor points and abnormal anchor points. Each anchor point has a display color corresponding to the anchor point. Anchor points of different anchor point types may have different display colors. For example, the display color corresponding to an abnormal anchor point may be a first display color. The display color corresponding to a normal anchor point may be a second display color. For example, the first display color is red, and the second display color is green. An abnormal anchor point may refer to an offset anchor point. For example, an anchor point whose position offset data does not fall within the position offset range may be determined as an abnormal anchor point.

[0049] According to an embodiment of the present disclosure, a client can determine whether a first display color exists in the display colors of at least one positioning point. If it is determined that the first display color exists in the display colors of at least one positioning point, it can be indicated that an abnormal positioning point exists. In this case, the client can generate a data generation request. The client can send a data generation request to a server, so that the server, in response to receiving the data generation request from the client, regenerates the positioning data corresponding to each of the at least one positioning point based on data generation rules, thereby obtaining at least one new positioning data. The server can send the at least one new positioning data to the client.

[0050] According to an embodiment of the present disclosure, in response to receiving at least one new positioning data from a server, a client may perform a rendering operation using scene parameters and camera parameters to visually display each anchor point at its new display position under a determined display perspective. The new display position of the anchor point may be determined based on the new positioning data of the anchor point.

[0051] According to an embodiment of the present disclosure, a client can determine whether the first display color exists in the new display color of at least one anchor point. If the first display color exists in the new display color of at least one anchor point, the client can perform an operation of visually displaying the at least one anchor point at the new display position. This operation continues until it is determined that the first display color does not exist in the new display color of at least one anchor point.

[0052] According to an embodiment of the present disclosure, by displaying color information to determine whether there is an abnormal positioning point in at least one positioning point, it is convenient to intuitively understand the specific situation of the positioning data, thereby improving the efficiency and accuracy of the positioning data quality assessment.

[0053] According to an embodiment of the present disclosure, the above-mentioned high-precision map data display method may also include the following operations.

[0055] According to an embodiment of the present disclosure, the position offset range can be used as a basis for determining the type of positioning point to which the positioning point belongs. The position offset range can be configured according to actual business needs and is not limited here.

[0056] According to an embodiment of the present disclosure, for each of at least one anchor point, a determination is made as to whether the position offset data of the anchor point falls within a position offset range. If the position offset data of the anchor point is determined not to fall within the position offset range, the anchor point may be determined to be an abnormal anchor point. The display color of the abnormal anchor point may be set to the first display color.

[0057] According to an embodiment of the present disclosure, the above-mentioned high-precision map data display method may also include the following operations.

[0058] If it is determined that the position offset data of the anchor point falls within the position offset range, the anchor point is determined to be a normal anchor point, and the display color of the normal anchor point is determined to be the second display color.

[0059] According to an embodiment of the present disclosure, if it is determined that the position offset data of the anchor point belongs to the position offset range, the anchor point can be determined to be a normal anchor point. The display color of the normal anchor point can be set to the second display color.

[0060] According to an embodiment of the present disclosure, the above-mentioned high-precision map data display method may also include the following operations.
