Description

Technical Field

[0001] The present invention relates to the technical field of map generation, and specifically to a method and system for generating 1:2000 topographic maps based on multi-source data fusion. Background Art

[0002] A topographic map refers to a projection map of the surface undulation form, geographical location, and shape on a horizontal plane. However, there are also roads on the topographic map. According to the topographic map, the slope situation of the road can be better judged. At the same time, the topographic map can help drivers or cyclists understand the topographic features around the road, enabling people to better understand the spatial layout of the route during navigation, improving people's understanding of the road, providing detailed road information while also providing topographic background information to help users better select suitable locations. The topographic map can also help rescue personnel determine the best rescue route and understand the terrain complexity of the disaster area;

[0003] When common topographic map generation methods and systems are in use, they lack in-depth analysis and integration of the walking conditions of different age groups, resulting in the topographic map being unable to reflect practical information such as the walking difficulty of different age groups, failing to effectively associate the number of steps with the road length and apply it to the topographic map, and having poor consideration for the generality of the topographic map under different means of transportation. For this reason, we propose a method and system for generating 1:2000 topographic maps based on multi-source data fusion. Summary of the Invention

[0068] In S500, when replacing the stage-based step distance standard with the spacing information, let the roller circumference be G 周长, let the number of rolling times required for different road lengths be G 圈数 ;

[0069]

[0070] Calculate the number of rolling times required for different road lengths according to the above formula, then establish a verification terminal, which includes a Hall sensor and a verification road. Then extract the road lengths for which the number of rolling times has been calculated, analyze their road information, and use this road information as the verification road. Analyze the mobile tool corresponding to the tool name information. Install the Hall sensor on the wheel of the mobile tool, and then let the mobile tool drive through the verification road. Use the detection of the Hall sensor to obtain the number of rolling circles of the wheel when the mobile tool drives through the verification road, generate the verification number of circles, establish a reminder range threshold, and then extract the number of rolling times required for different road lengths. Calculate the ratio of the verification number of circles to the number of rolling times. When the ratio of the verification number of circles to the number of rolling times is not within the reminder range threshold, the staff will be reminded to check. When the ratio of the verification number of circles to the number of rolling times is within the reminder range threshold, it will be considered normal information;

[0071] When selecting the verification road, it is not limited to the actual existing roads. Virtual simulation technology should also be combined to construct diverse verification scenarios, simulate roads under extreme terrain conditions and roads in special scenarios, test the number of rolling circles of the tool on these virtual verification roads, and comprehensively monitor the motion state of the mobile tool in combination with other sensors;

[0072] Collect a large amount of actual verification data of users under different road conditions and different tool usage situations, and use big data analysis technology to mine the rules and patterns in them. By analyzing these data, not only can the setting of the reminder range threshold be optimized, but also a more intelligent reminder strategy can be formulated;

[0073] In S600, when formulating the exercise target distance for the user using the physical limit plan and the target route information, it is necessary to extract the different flatness road lengths existing in the exercise route information and the road length information of the exercise route information. Let the physical information of the user be P 体能 , let the different flatness road lengths existing in the exercise route information be P Z , let the exercise target distance be P 目标 , let the number of different flatness roads be U.

[0076] Specific workflow: Calculate the number of rolling times required for different road lengths, extract the road lengths for which the number of rolling times has been calculated, analyze their road information, and use this road information as the verification road. Install a Hall sensor on the wheel of the mobile tool, then let the mobile tool drive through the verification road, use the Hall sensor to detect the number of rolling circles of the wheel when the mobile tool drives through the verification road, extract the number of rolling times required for different road lengths, calculate the ratio of the verification circles to the number of rolling times. When the ratio of the verification circles to the number of rolling times is not within the reminder range threshold, the staff will be reminded to check. When the ratio of the verification circles to the number of rolling times is within the reminder range threshold, it will be regarded as normal information. Extract the lengths of roads with different flatness levels and the road length information in the movement route information in the movement route information, and calculate the movement target distance;

[0077] Furthermore, by using a standardized calculation method to obtain the number of rolling times of the tool on different roads, it realizes a reasonable increase in the moving scenarios from walking to using tools, enriches the application capabilities of the system under different travel modes, enables better association with road lengths, promptly captures significant deviations between the system calculation results and the actual situation, and thus promptly improves the distance representation of different tools on the topographic map.

The method for generating a 1:2000 topographic map based on multi-source data fusion according to claim 6, wherein: In the S500, when replacing the phased step standard with the spacing information, let the roller circumference be G 周长 , let the number of rolling times required for different road lengths be G 圈数 ; Calculate the number of rolling times required for different road lengths according to the above formula. Then establish a verification terminal, which includes a Hall sensor and a verification road. Then extract the road length for which the number of rolling times has been calculated, analyze its road information, and use this road information as the verification road. Analyze the mobile tool corresponding to the tool name information. Install the Hall sensor on the wheel of the mobile tool. Then let the mobile tool drive through the verification road, and use the detection of the Hall sensor to count the number of rolling circles of the wheel when the mobile tool drives through the verification road to generate the verification circle number. Establish a reminder range threshold. Then extract the number of rolling times required for different road lengths, and calculate the ratio of the verification circle number to the number of rolling times. When the ratio of the verification circle number to the number of rolling times is not within the reminder range threshold, the staff will be reminded to check. When the ratio of the verification circle number to the number of rolling times is within the reminder range threshold, it will be regarded as normal information.
