Description

Technical Field

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

[0002] A topographic map refers to the projection of the surface undulations, geographic location, and shape on a horizontal plane. However, there are also roads on the topographic map. The slope of the road can be better judged based on the topographic map. At the same time, the topographic map can help drivers or cyclists understand the terrain features around the road, so that people can better understand the spatial layout of the route during navigation, and improve people's understanding of the road. While providing detailed road information, it can also provide terrain background information to help users better choose the right location. The topographic map can also help rescuers determine the best rescue route and understand the complexity of the terrain in the disaster area;

[0003] Common topographic map generation methods and systems lack in-depth analysis and integration of walking conditions of different age groups when used, resulting in the inability of topographic maps to reflect practical information such as walking difficulty of different age groups. They fail to effectively associate the number of steps with road length and apply them to topographic maps, and the versatility of topographic maps under different mobile tools is poorly considered. Therefore, we propose a 1:2000 topographic map generation method and system based on multi-source data fusion. Summary of the invention

[0004] The purpose of the present invention is to provide a 1:2000 topographic map generation method and system based on multi-source data fusion.

[0005] In order to solve the problems raised in the above background technology, the present invention provides the following technical solution: a 1:2000 topographic map generation method based on multi-source data fusion, comprising the following steps:

[0006] S100, preliminarily acquiring terrain information, obtaining preliminary terrain information, preliminarily drawing a three-dimensional terrain map based on the preliminary terrain information and three-dimensional software, and obtaining detailed terrain map information;

[0007] S200, establishing unique accounts for different users, and recording user information in real time, collecting user age information, analyzing walking information of different ages, analyzing the number of steps required for different ages to complete walking at the same distance, calculating the average stride distance of different ages, obtaining stage-based stride standards, and collecting user daily exercise information at the same time, analyzing the user's exercise distance information based on the user's daily exercise information and user age information, and recording the exercise distance information as the user's physical fitness information;

[0008] S300, extracting detailed topographic map information, and dividing the detailed topographic map into roads to obtain road information, analyzing the road lengths in different road information, and then calculating the number of steps required to walk different road lengths according to the staged step length standard, and covering the road lengths with the calculated number of steps, and then analyzing the flatness of different roads according to the detailed topographic map information to obtain flatness road information, extracting the number of steps of the user on roads of different flatnesses, calculating the number of steps of the user on roads of different flatnesses Physical energy consumption, and setting a speed limit unit at the same time, treating the movement speed below the speed limit unit as non-movement speed information;

[0009] S400, formulate individual replacement thresholds for different users, record the time and walking information of users using detailed topographic maps in real time, when the walking information of users using detailed topographic maps is less than the individual replacement threshold, the number of steps required to pass different road lengths will be calculated using the staged step length standard, when the number of steps of users using detailed topographic maps is greater than the individual replacement threshold, the staged step length standard will be replaced using the walking information of users using detailed topographic maps, and then the calculated number of steps will be marked on the road information;

[0010] S500, establishing a tool replacement unit, wherein the tool replacement unit includes tool name information and spacing information, constructing a three-dimensional model using the tool name information, collecting the movement mode and roller circumference of the tool using the spacing information, and obtaining spacing information. After the user completes the information input of the tool replacement unit, the spacing information will be replaced with the staged step standard, and then the number of rolls required to pass through different road lengths will be calculated and marked on the road information in the detailed topographic map;

[0011] S600. Formulate a physical fitness limit plan based on the user's physical fitness information. Then the user selects road information from different road information to obtain exercise route information. Analyze the road information of different flatnesses in the exercise route information to obtain target route information. Use the physical fitness limit plan and target route information to formulate an exercise target distance for the user.

[0012] As a further solution of the present invention: In the above S200, when calculating the average crossing distance of different ages, different step number information of different ages at the same distance is collected. Suppose the walking distance is X 距离 , let the step number information be B S , let the number of steps collected be L, let the average distance crossed be P 平均 ;

[0013]

[0014] The average stride distance in different stages is calculated according to the above formula to improve the stage-by-stage stride standard information.

[0015] As a further solution of the present invention: In S300, when calculating the number of steps required to walk different road lengths according to the staged step length standard, the road length is assumed to be D L , assuming that the stage step standard is J 标准 , let B be the number of steps required to walk different road lengths S ;

[0016]

[0017] According to the above formula, the number of steps required to walk different road lengths can be calculated.

[0018] As a further solution of the present invention: in S300, the stage-by-stage stride standard has two expressions, the first is a specific value, and the second is a range value. When the stage-by-stage stride standard is a specific value, the specific number of steps required to walk different road lengths is calculated according to the formula; when the stage-by-stage stride standard is a range value, the range of steps required to walk different road lengths is calculated according to the formula.

[0019] As a further solution of the present invention: in the above S300, when calculating the physical energy consumption of the number of steps of the user on roads of different flatness, the number of steps on the flat road is extracted from the number of steps of the user on roads of different flatness, and the number of steps of the user on the flat road is set as P 步数 , let the number of steps taken by the user on roads of different flatness be B 步数 , assuming that the number of steps the user takes on roads of different flatness is B T ;

[0020]

[0021] The above formula is used to calculate the user's physical energy consumption based on the number of steps taken on roads of different flatness.

[0022] As a further solution of the present invention: In the above S400, when formulating personal replacement thresholds for different users, an age change standard is established, and the changes in the number of steps to be collected at different ages are analyzed according to the age change standard. At the same time, a step number benchmark is formulated, and the minimum value of the collected steps is determined based on the step number basis. The influence of the human body on the physiological structure in the age direction is analyzed, and the age benchmark is determined. The age change standard is set as N 标准 , let the age base be N 基准 , let the step number base be B 基准 , assuming that the threshold of individual replacement is G 阈值 , let the age of different users be N 年龄 ;

[0023] G 阈值 =|N 基准 -N 年龄 |×N标准 +B 基准

[0024] The individual replacement threshold is calculated according to the above formula.

[0025] As a further solution of the present invention: in the above S500, when the spacing information is replaced with the staged step standard, the circumference of the roller is G 周长 , let G be the number of rolling times required to pass different road lengths 圈数 ;

[0026]

[0027] According to the above formula, the number of rolling times required to pass through different road lengths is calculated, and then a verification terminal is established. The verification terminal includes a Hall sensor and a verification road. Then, the road length for which the number of rolling times has been calculated is extracted, and its road information is analyzed. The road information is used as the verification road. The mobile tool corresponding to the tool name information is analyzed, and the Hall sensor is installed on the wheel of the mobile tool. Then, the mobile tool is driven through the verification road. The number of rolling circles of the wheels when the mobile tool passes through the verification road is detected by the Hall sensor to generate the number of verification circles, establish a reminder range threshold, and then extract the number of rolling times required to pass through different road lengths. The ratio of the number of verification circles to the number of rolling times is calculated. When the ratio of the number of verification circles to the number of rolling times is not between the reminder range threshold, the staff will be reminded to check. When the ratio of the number of verification circles to the number of rolling times is within the reminder range threshold, it will default to normal information.

[0028] As a further solution of the present invention: in the above S600, when using the physical fitness limit program and the target route information to set the sports target distance for the user, it is necessary to extract the road lengths of different flatnesses in the sports route information and the road length information of the sports route information. Suppose the user's physical fitness information is P 体能 , let the length of roads with different flatness in the motion route information be P Z , let the moving target distance be P 目标 , let the number of roads with different roughness be U.

[0029]

[0030] The distance of the moving target is calculated according to the above formula.

[0031] In addition, a 1:2000 topographic map generation system based on multi-source data fusion is also proposed, which is suitable for the 1:2000 topographic map generation method based on multi-source data fusion.

[0032] By adopting the above technical solution, compared with the prior art, the beneficial effects of the present invention are:

[0033] 1. The present invention helps to associate the number of steps with the length of the road by analyzing the walking conditions of people of different ages, so that the topographic map is no longer just a display of geographical features, but can intuitively reflect practical information related to walking such as walking difficulty, and timely update the standards according to their actual walking conditions, so that when users use the topographic map for viewing, they can better analyze the road length according to their own status, thereby improving the overall versatility and practicality, and can provide users with the distance of the moving target, so that the road length on the topographic map can be better reflected, and the user's distance experience of the system can be improved;

[0034] 2. The present invention can better reflect the actual situation of different age groups during walking by collecting step information of different ages at the same distance, convert the distance concept into specific step information, so that users can better understand the road distance in the detailed topographic map, and better deal with uncertain factors when planning their trips. The system can be optimized and adjusted according to the user, so that the association between the entire walking information and the topographic map is more in line with the user's actual situation, and the user can understand the step physical energy consumption information on the roads of different flatness;

[0035] 3. The present invention obtains the number of times the tool rolls on different roads through a standardized calculation method, thereby achieving a reasonable increase in the movement scenarios from walking to using tools, enriching the application capabilities of the system under different travel modes, making different bases better associated with road lengths, and timely capturing significant deviations between the system calculation results and the actual situation, thereby timely improving the distance representation of different tools on the topographic map.

[0047] Specific workflow: improve the simplified topographic map, obtain detailed topographic map information, calculate the average span distance of different ages, obtain the staged stride standard, analyze the user's movement distance information according to the user's daily movement information and user age information, and record the movement distance information as the user's physical fitness information, analyze the road length in different road information, use the calculated number of steps to cover the road length, and then calculate the user's step physical energy consumption on roads of different flatness, regard the movement speed below the speed limit unit as non-movement speed information, formulate personal replacement thresholds for different users, record the time and walking information of users using detailed topographic maps in real time, judge the relationship between the walking information of users when using detailed topographic maps and the personal replacement threshold, use the spacing information to collect the tool's movement mode and roller circumference, replace the staged stride standard with the spacing information, and then calculate the number of rolls required to pass different road lengths, and mark it on the road information in the detailed topographic map, and use the physical fitness limit plan and target route information to formulate the user's movement target distance;

[0048] Furthermore, by analyzing the walking conditions of people of different ages, it helps to associate the number of steps with the length of the road, so that the topographic map is no longer just a display of geographical features, but can intuitively reflect practical information related to walking, such as walking difficulty, and timely update the standards according to their actual walking conditions, so that when users use the topographic map for viewing, they can better analyze the road length according to their own status, thereby improving the overall versatility and practicality, and can provide users with the distance of the movement target, so that the road length on the topographic map can be better reflected, thereby improving the user's distance experience of the system.

[0049] Embodiment 2:

[0050] Based on the first embodiment, as shown in the accompanying drawings of the specification Figure 1 As shown, in S200, when calculating the average crossing distance of different ages, different step number information of different ages at the same distance is collected. Suppose the walking distance is X 距离 , let the step number information be B S , let the number of steps collected be L, let the average distance crossed be P 平均 ;

[0051]

[0052] According to the above formula, the average stride distance in different stages is calculated to improve the stage-by-stage stride standard information;

[0053] At the same time, the adaptation conditions of different ages to roads with different slopes are collected, and the detailed physical energy consumption of users after adapting to roads with different slopes is analyzed, so that users can consider more complete directions when improving the staged stride standard information;

[0054] In addition to collecting walking information of different ages at one time, a dynamic monitoring mechanism should be established to update the data regularly. As time goes by, people's physical conditions and walking habits may change, especially for the elderly and young people. By regularly re-collecting data, these changes can be captured in time, making the calculation of the average walking distance more in line with the actual situation.

[0055] In S300, when calculating the number of steps required to walk different road lengths according to the staged step length standard, assume that the road length is D L , assuming that the stage step standard is J 标准 , let B be the number of steps required to walk different road lengths S ;

[0056]

[0057] According to the above formula, the number of steps required to walk different road lengths is calculated;

[0058] In S300, the staged step length standard has two expression modes, the first is a specific value, and the second is a range value. When the staged step length standard is a specific value, the specific number of steps required to walk different road lengths is calculated according to the formula. When the staged step length standard is a range value, the range of steps required to walk different road lengths is calculated according to the formula.

[0059] In S300, when calculating the physical energy consumption of the number of steps of the user on roads of different flatness, the number of steps on the flat road is extracted from the number of steps of the user on roads of different flatness, and the number of steps of the user on the flat road is set as P 步数 , let the number of steps taken by the user on roads of different flatness be B 步数 , assuming that the number of steps the user takes on roads of different flatness is B T ;

[0060]

[0061] According to the above formula, the user's step count and physical energy consumption on roads of different flatness are calculated;

[0062] Specific workflow: Collect different step count information of different ages at the same distance, calculate the average span distance of different stages, improve the stage-by-stage step length standard information, calculate the number of steps required to walk different road lengths, when the stage-by-stage step length standard is a specific value, calculate the specific number of steps required to walk different road lengths according to the formula, when the stage-by-stage step length standard is a range value, calculate the range of steps required to walk different road lengths according to the formula, establish age change standards, analyze the changes in the number of steps that need to be collected at different ages according to the age change standards, calculate the user's step energy consumption on roads of different flatness, and formulate a step number benchmark at the same time. Determine the minimum value of the collected steps based on the step number basis, analyze the impact of the human body on the physiological structure in the age direction, determine the age benchmark, and calculate the personal replacement threshold;

[0063] Furthermore, by collecting step information of people of different ages at the same distance, the actual situation of different age groups during walking can be better reflected, and the concept of distance can be converted into specific step information, so that users can better understand the road distance in the detailed topographic map, and can better deal with uncertain factors when planning their itineraries, so that the system can be optimized and adjusted according to the user, so that the association between the entire walking information and the topographic map is more in line with the user's actual situation, and the user can understand his or her own step physical energy consumption information on roads of different flatness.

[0064] Embodiment three:

[0065] Based on the second embodiment, as shown in the accompanying drawings of the specification Figure 1 As shown, in S400, when formulating personal replacement thresholds for different users, an age change standard is established, and the changes in the number of steps to be collected at different ages are analyzed according to the age change standard. At the same time, a step number benchmark is formulated, and the minimum value of the collected steps is determined based on the step number basis. The influence of the human body on the physiological structure in the age direction is analyzed, and the age benchmark is determined. The age change standard is set as N 标准 , let the age base be N 基准 , let the step number base be B 基准 , assuming that the threshold of individual replacement is G 阈值 , let the age of different users be N 年龄 ;

[0066] G 阈值 =|N 基准 -N 年龄 |×N 标准 +B 基准

[0067] The individual turnover threshold is calculated according to the above formula;

[0068] In S500, when the spacing information is replaced with the step-by-step pitch standard, the circumference of the roller is G. 周长, let G be the number of rolling times required to pass different road lengths 圈数 ;

[0069]

[0070] According to the above formula, the number of rolling times required to pass through different road lengths is calculated, and then a verification terminal is established. The verification terminal includes a Hall sensor and a verification road. Then, the road length for which the number of rolling times has been calculated is extracted, and its road information is analyzed. The road information is used as the verification road. The mobile tool corresponding to the tool name information is analyzed, and the Hall sensor is installed on the wheel of the mobile tool. Then, the mobile tool is driven through the verification road. The Hall sensor is used to detect the number of rolling circles of the wheels when the mobile tool passes through the verification road, and the verification circle number is generated. A reminder range threshold is established, and then the number of rolling times required to pass through different road lengths is extracted, and the ratio of the verification circle number to the rolling number is calculated. When the ratio of the verification circle number to the rolling number is not between the reminder range threshold, the staff will be reminded to check. When the ratio of the verification circle number to the rolling number is within the reminder range threshold, it will default to normal information.

[0071] When selecting verification roads, we should not only limit ourselves to actual roads, but also build diversified verification scenarios in combination with virtual simulation technology, 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 combine with other sensors to monitor the movement status of the mobile tool in all directions;

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

[0073] In S600, when the physical fitness limit program and the target route information are used to set the exercise target distance for the user, it is necessary to extract the length of roads with different flatness and the road length information of the exercise route information. Suppose the user's physical fitness information is P 体能 , let the length of roads with different flatness in the motion route information be P Z , let the moving target distance be P 目标 , let the number of roads with different roughness be U.

[0074]

[0075] Calculate the moving target distance according to the above formula;

[0076] Specific workflow: calculate the number of rolls required to pass through different road lengths, extract the road length for which the rolls have been calculated, analyze the road information, and use the road information as a verification road. Install the Hall sensor on the wheels of the mobile tool, and then make the mobile tool pass through the verification road. Use the Hall sensor to detect the number of rolls of the wheels when the mobile tool passes through the verification road, extract the number of rolls required to pass through different road lengths, calculate the ratio of the number of verification circles to the number of rolls, and when the ratio of the number of verification circles to the number of rolls is not within the reminder range threshold, the staff will be reminded to check. When the ratio of the number of verification circles to the number of rolls is within the reminder range threshold, it will default to normal information, extract the road lengths of different flatnesses in the motion route information and the road length information of the motion route information, and calculate the distance of the moving target;

[0077] Furthermore, by using a standardized calculation method to obtain the number of times the tool rolls on different roads, a reasonable increase in movement scenarios from walking to using tools is achieved, enriching the system's application capabilities under different travel modes, making different bases better associated with road lengths, and timely capturing significant deviations between the system's calculation results and the actual situation, thereby timely improving the distance representation of different tools on the topographic map.

[0078] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.

The method for generating a 1:2000 topographic map based on multi-source data fusion according to claim 6, characterized in that: In the above S500, when the spacing information is replaced with the staged step standard, the circumference of the roller is G. 周长 , let G be the number of rolling times required to pass different road lengths 圈数 ; According to the above formula, the number of rolling times required to pass through different road lengths is calculated, and then a verification terminal is established. The verification terminal includes a Hall sensor and a verification road. Then, the road length for which the number of rolling times has been calculated is extracted, and its road information is analyzed. The road information is used as the verification road. The mobile tool corresponding to the tool name information is analyzed, and the Hall sensor is installed on the wheel of the mobile tool. Then, the mobile tool is driven through the verification road. The number of rolling circles of the wheels when the mobile tool passes through the verification road is detected by the Hall sensor to generate the number of verification circles, establish a reminder range threshold, and then extract the number of rolling times required to pass through different road lengths. The ratio of the number of verification circles to the number of rolling times is calculated. When the ratio of the number of verification circles to the number of rolling times is not between the reminder range threshold, the staff will be reminded to check. When the ratio of the number of verification circles to the number of rolling times is within the reminder range threshold, it will default to normal information.
