Detailed Description

Exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings, in which various details of the embodiments of the disclosure are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

The applicant finds that the current mainstream map updating operation mode is as follows in the research and development process: the server side uniformly issues the map updating information of the target track point and the index information of the target track point to the local client side, the binding relationship between the map updating information and the index information is also recorded in a download file, and when an operator selects the map updating information, the target track image of the target track point is automatically opened based on the corresponding index information. And the operator updates the map based on the target track image.

However, the disadvantage of this operation mode is that if the operator operates the same target trace point for multiple times, the problem that the server repeatedly issues the index information of the target trace point is caused, which results in redundant issuing of the index information, increases the data volume of the data issued by the server, increases the pressure of the server, and the server also occupies extra bandwidth and machine resources.

Fig. 1 is a flowchart of some image processing methods disclosed according to an embodiment of the present disclosure, which may be applied to a case of determining a target track image of a target track point in a map updating process. The method of the present embodiment may be executed by the image processing apparatus disclosed in the embodiments of the present disclosure, and the apparatus may be implemented by software and/or hardware, and may be integrated on any electronic device with computing capability.

As shown in fig. 1, the image processing method disclosed in this embodiment may include:

s101, obtaining map updating information of a target track point from a server; the map update information includes a target track point identification of the target track point.

The server represents a service server for map updating. The target track point represents the track point related to the map updating, the track point is an acquisition point for acquiring an image once in the field of the map, and the acquisition point corresponds to at least one acquisition image and one acquisition position, namely the track point image and the track point position. The map update information represents material for instructing an operator to update the map data based on a specific map element, and is generated by means of program recognition or manual recording, and in this embodiment, the map update information includes a map element to be updated and a target track point identification of an associated target track point. The target track point identification represents identification information capable of uniquely representing the target track point.

In an embodiment, when a target track point needs to be updated, a server determines a map element of the target track point that needs to be updated through a program identification or manual recording mode, for example, a map element included in a target track image corresponding to the target track point is identified through a target detection method, and for example, a map element included in the target track image is framed through a manual framing mode. And the server side further generates map updating information of the target track point according to the map elements needing to be updated of the target track point and the target track point identification of the target track point. And the server sends the map updating information to the local client based on a preset communication protocol and the address information. The information format of the map update information includes, but is not limited to, the exto format.

The local client acquires the map updating information of the target track points from the server and displays the map updating information in a list mode, wherein the number of the target track points can be one or more. The method comprises the following steps that an operator selects any map updating information to operate, namely when the number of target track points is one, the operator selects the map updating information of the target track points to operate; and when the number of the target track points is multiple, the operator selects the map updating information of one target track point from the multiple target track points to operate.

The map updating information of the target track point is obtained from the server, so that a foundation is laid for subsequently determining the cache state of the target index information in the local client.

S102, determining the cache state of the target index information in the local client according to the map updating information; the target index information includes the target track point identification.

The target index information indicates index information of a target track point corresponding to the target track image, and the target track image can be obtained through a Uniform Resource Locator (URL) address in the target index information. The target index information includes target track point identifiers of target track points, and the like, in addition to the URL addresses of the target track images. The information format of the index information includes, but is not limited to, the exto format.

In this embodiment, after the local client obtains the index information of any track image from the server, the local client locally caches the index information, so that the index information is multiplexed, and the server does not need to issue the index information together with the map update information each time.

In one implementation, the local client analyzes the map update information, and obtains a target track point identifier of a target track point included in the map update information. And matching the target track point identification with the index information cached in the local client, and determining whether the local client caches the target index information corresponding to the target track point.

And if any cached index information of the local client comprises the target track point identification, determining that the caching state of the target index information in the local client is a cached state. Namely, the target index information of the target track point is cached in the local client.

And if all cached index information of the local client does not comprise the target track point identification, determining that the caching state of the target index information in the local client is an uncached state. That is, the target index information of the target track point is not cached in the local client.

The caching state of the target index information in the local client is determined according to the map updating information, so that the effect of determining whether the local client caches the target index information is achieved, and a foundation is laid for obtaining the target index information according to the caching state subsequently.

S103, acquiring the target index information according to the cache state of the target index information, and determining a target track image of the target track point according to the acquired target index information.

The target track image is an acquired image corresponding to the target track point.

In one embodiment, if the local client determines that the cache state of the target index information is the cached state, the local client acquires the target index information from the local client, acquires the URL address of the target track image of the target track point from the target index information, and further determines the target track image of the target track point from the internet based on the URL address.

In another embodiment, if the local client determines that the cache state of the target index information is an uncached state, the local client obtains the target index information from the server and caches the target index information in the local client. And acquiring the URL address of the target track image of the target track point from the target index information, and further determining the target track image of the target track point from the Internet based on the URL address.

After determining the target track image of the target track point, the local client renders the target track image to display the target track image, and the operator updates the map data based on the displayed target track image.

The method and the device have the advantages that the map updating information of the target track point is obtained from the server, the cache state of the target index information in the local client is determined according to the map updating information, the target index information is further obtained according to the cache state of the target index information, and the target track image of the target track point is determined according to the obtained target index information.

S2021, determining that the cached state of the target index information in the local client is the cached state when the index information cached in the local client includes the target track point identifier, and executing S2031.

In one embodiment, the local client matches the target track point identifier with each cached index information, determines whether any cached index information includes the target track point identifier, and determines that the caching state of the target index information in the local client is the cached state if the target track point identifier is included in any cached index information.

Optionally, the target track point identifier includes position information and number information of the target track point. Correspondingly, the cached index information includes the position information and the number information of the track point.

For example, assuming that the position information of the target track point is (X, Y, Z), matching the position information (X, Y, Z) with the position information of the track point in each cached index information, and if any cached index information includes the position information (X, Y, Z), determining that the caching state of the target index information in the local client is the cached state.

By setting the position information and the number information of the target track point mark including the target track point, the richness of the target track point mark is ensured, and the diversity of means for matching the subsequent target track point marks is increased.

S2022, determining that the cached state of the target index information in the local client is an uncached state when the index information cached by the local client does not include the target track point identifier, and executing S2032.

In one embodiment, the local client matches the target track point identifier with each piece of cached index information, determines whether any piece of cached index information includes the target track point identifier, and if not, determines that the caching state of the target index information in the local client is an uncached state.

For example, assuming that the position information of the target track point is (X, Y, Z), matching the position information (X, Y, Z) with the position information of the track point in each cached index information, and if all cached index information does not include the position information (X, Y, Z), determining that the caching state of the target index information in the local client is an uncached state.

S2031, under the condition that the cache state is the cached state, acquiring index information matched with the target track point identifier from the local client as target index information.

In one embodiment, the local client uses the cached index information matched with the target track point identifier as the target index information.

For example, assuming that the position information of the target track point is (X, Y, Z), the position information (X, Y, Z) is matched with the position information of the track point in each piece of cached index information, and if the index information a includes the position information (X, Y, Z), the index information a is used as the target index information.

S2032, under the condition that the cache state is not the cache state, obtaining the index information matched with the target track point identification from the server side as the target index information, and caching the target index information in the local client side.

In one implementation, the local client generates an index information request according to the target track point identifier, and sends the index information request carrying the target track point identifier to the server, so that the server feeds back target index information matched with the target track point identifier to the local client.

For example, assuming that the position information of the target track point is (X, Y, Z), matching the position information (X, Y, Z) with the position information of the track point in each cached index information, if all cached index information does not include the position information (X, Y, Z), sending an index information request carrying the position information (X, Y, Z) to the server, and feeding back the index information matched with the position information (X, Y, Z) as the target index information to the local client by the server.

And S204, determining a target track image of the target track point according to the acquired target index information, and displaying the target track image of the target track point to be used as map updating guide information of the target track point.

The local client renders the target track image to display the target track image, and the operator uses the target track image as map updating guide information to update the map data associated with the target track point.

According to the method and the device, the cache state of the target index information in the local client is determined to be the cached state under the condition that the index information cached by the local client comprises the target track point identification, and the cache state of the target index information in the local client is determined to be the uncached state under the condition that the index information cached by the local client does not comprise the target track point identification, so that the effect of determining the cache state of the target index information in the local client based on the target track point identification is realized, and a foundation is laid for acquiring the target index information by adopting different technical means based on different cache states subsequently; by acquiring index information matched with the target track point identifier from the local client side as target index information under the condition that the cache state is the cached state, the effect of local multiplexing of the cache information is realized, and the data volume of data issued by the server side is reduced; by acquiring the index information matched with the target track point identifier from the server side as the target index information and caching the target index information in the local client side under the condition that the cache state is the uncached state, the effect of acquiring and caching the target index information from the server side is realized, and a foundation is laid for multiplexing the target index information at the local client side subsequently; the target track image of the target track point is displayed and used as map updating guide information of the target track point, so that the effect of assisting operators to update map data through the target track image is achieved, and the accuracy of map data updating is guaranteed.

Fig. 2B is a schematic diagram showing some target track images according to the embodiment of the present disclosure, as shown in fig. 2B, 20 indicates target track points, and after the target track image 21 of the target track point 20 is determined, the target track image 21 is shown to be used as map update guide information of the target track point 20.

The applicant also finds that, in the currently mainstream map updating operation mode, because the server only issues the index information of the target track point and the map updating information in a unified manner, a limited number of track point images that can be referred to by the operator are fixed, that is, only the target track image corresponding to the target track point exists, so that under the road conditions such as a complex intersection and the like, the image information that the operator can refer to is too little, some special map elements may be omitted, the quality of the map updating result is low, and even the map updating cannot be performed.

These program codes may be provided to a processor or controller of a general purpose computer, special purpose computer, or other programmable data processing apparatus, such that the program codes, when executed by the processor or controller, cause the functions/operations specified in the flowchart and/or block diagram to be performed. The program code may execute entirely on the machine, partly on the machine, as a stand-alone software package partly on the machine and partly on a remote machine or entirely on the remote machine or server.

In the context of this disclosure, a machine-readable medium may be a tangible medium that can contain, or store a program for use by or in connection with an instruction execution system, apparatus, or device. The machine-readable medium may be a machine-readable signal medium or a machine-readable storage medium. A machine-readable medium may include, but is not limited to, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, or device, or any suitable combination of the foregoing. More specific examples of a machine-readable storage medium would include an electrical connection based on one or more wires, a portable computer diskette, a hard disk, a Random Access Memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or flash memory), an optical fiber, a portable compact disc read-only memory (CD-ROM), an optical storage device, a magnetic storage device, or any suitable combination of the foregoing.

To provide for interaction with a user, the systems and techniques described here can be implemented on a computer having: a display device (e.g., a CRT (cathode ray tube) or LCD (liquid crystal display) monitor) for displaying information to a user; and a keyboard and a pointing device (e.g., a mouse or a trackball) by which a user can provide input to the computer. Other kinds of devices may also be used to provide for interaction with a user; for example, feedback provided to the user can be any form of sensory feedback (e.g., visual feedback, auditory feedback, or tactile feedback); and input from the user may be received in any form, including acoustic, speech, or tactile input.

The systems and techniques described here can be implemented in a computing system that includes a back-end component (e.g., as a data server), or that includes a middleware component (e.g., an application server), or that includes a front-end component (e.g., a user computer having a graphical user interface or a web browser through which a user can interact with an implementation of the systems and techniques described here), or any combination of such back-end, middleware, or front-end components. The components of the system can be interconnected by any form or medium of digital data communication (e.g., a communication network). Examples of communication networks include: local Area Networks (LANs), Wide Area Networks (WANs), blockchain networks, and the internet.

The computer system may include clients and servers. A client and server are generally remote from each other and typically interact through a communication network. The relationship of client and server arises by virtue of computer programs running on the respective computers and having a client-server relationship to each other. The server can be a cloud server, also called a cloud computing server or a cloud host, and is a host product in a cloud computing service system, so that the defects of high management difficulty and weak service expansibility in the traditional physical host and VPS service are overcome.
