Embodiment 1

[0031] figure 1 It is a flow chart of the navigation evaluation method provided by Embodiment 1 of the present invention. This embodiment is applicable to the evaluation of navigation applications. The method can be executed by a navigation evaluation device, which can use software and / or hardware Realized, and can be integrated on computer equipment. Such as figure 1 As shown, the method may include:

[0032] S110. For multiple different paths, respectively acquire navigation videos based on each path by different navigation applications.

[0033] In this embodiment, the navigation video is a real navigation video for a specific route, and the current speed of the vehicle can be displayed in real time on the navigation screen. The navigation video can be obtained from the open navigation video library based on data statistics, or can be obtained by recording or simulating the navigation path in the real environment. Exemplarily, according to the starting point and end poi...

Embodiment 2

[0048] figure 2 It is a flow chart of the navigation evaluation method provided by Embodiment 2 of the present invention, and this embodiment is further optimized on the basis of the foregoing embodiments. Such as figure 2 As shown, the method may include:

[0049] S210. For multiple different paths, respectively acquire navigation videos of different navigation applications based on each path.

[0050] S220. Perform video conversion on different navigation videos corresponding to each path to obtain multiple frames of pictures.

[0051] Among them, after video conversion, a certain number of pictures can be extracted from the pictures included in each navigation video according to a preset time interval, such as 1 second, as pictures for subsequent identification of navigation data, and the number of pictures is not specified in this embodiment. limited. By converting navigation video into pictures, the difficulty of identifying navigation data can be reduced, thereby i...

Abstract

An embodiment of the invention discloses a navigation estimation method and device, computer equipment and a storage medium, wherein the navigation estimation method includes: acquiring, for differentpaths, navigation videos of different navigation applications based on each path; for each path, extracting real-time speeds and overspeed conditions respectively from the different navigation videoscorresponding to the path; comparing the real-time speeds and overspeed conditions extracted from the different navigation videos corresponding to the same path so as to estimate the navigation applications according to comparison results. The navigation estimation method and device, the computer equipment and the storage medium according to the embodiment help solve the problem that the poor accuracy of overspeed prompts is caused to the absence of effective estimation on navigating performances of navigation applications in the prior art; real-time speed and overspeed condition can be recognized from a navigation video; the navigating performance of each navigation application can be effectively estimated; therefore, the accuracy of overspeed prompts in the navigation process is guaranteed.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer technology, and in particular, to a navigation evaluation method, device, computer equipment and storage medium. Background technique [0002] The electronic navigation map has the functions of positioning display, index, route calculation and guidance, which brings great convenience to daily travel. [0003] In the process of using map navigation, if encountering a speed limit section on the road, the navigation application will prompt the user whether to exceed the speed limit according to the user's current real-time speed. More than 90% of drivers are very sensitive to whether the real-time speed display circle is red when using the navigation application, and they will adjust the speed in time according to whether the real-time speed display circle is red, so as to avoid fines and demerit points. [0004] Therefore, the precision and accuracy of the speed limit value in rout...
