Description

Technical Field

[0001] The present invention relates to the field of geographic information technology, and in particular to a method for collecting geographic information based on voice input. Background Art

[0002] Geographic information is the geographical meaning contained and expressed by geographic data. It is a general term for numbers, words, images and graphics that represent the quantity, quality, nature, distribution characteristics, connections and laws of materials related to geographical environment elements. First, geographic information belongs to spatial information, and its location identification is linked to data. This is the most significant feature that distinguishes geographic information from other types of information. Secondly, geographic information has the characteristics of a multidimensional structure. Thirdly, the temporal characteristics of geographic information are very obvious.

[0003] However, the current method of collecting geographic information based on voice input cannot achieve real-time selection for different environments, resulting in a single collection method, causing omissions in information collection and failing to achieve correct collection of geographic information. Summary of the invention

[0004] The present invention provides a method for collecting geographic information based on voice input, which can effectively solve the problem raised in the above background technology that the current method for collecting geographic information based on voice input cannot realize real-time selection for different environments, resulting in a single collection method, causing omissions in information collection, and failing to realize the correct collection of geographic information.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a method for collecting geographic information based on voice input, the collection method including automatic collection and manual collection;

[0006] The automatic collection is performed by directly collecting data through a collection device, converting the data, and then transmitting and storing the data to the outside world;

[0007] The manual collection requires personnel to go to the site, input relevant technical data, and obtain geographic information.

[0008] According to the above technical solution, the automatic acquisition includes an automatic acquisition system, and the automatic acquisition system includes: an acquisition device, a signal transmission device, a cloud information library, a comparison module and an output module;

[0009] The acquisition device, signal transmission device, cloud information library, comparison module and output module are all connected to the processor via a wireless network to form signal transmission;

[0010] The acquisition device includes a microphone, an input device and an aerial photography device;

[0011] The microphone collects voice information, the input device is one or more of a keyboard and a handwriting tablet, and the aerial photography device is a drone.

[0012] According to the above technical solution, the microphone is used for speech sampling and quantization, linear prediction analysis and cepstrum analysis.

[0013] Sampling and quantization: Sampling is to read the amplitude of the sound signal at regular intervals, while quantization is to convert the amplitude of the sampled sound signal into a digital value. Quantization is the digitization of the amplitude of the analog audio signal. The number of quantization bits determines the dynamic range of the analog signal after digitization. Commonly used ones are 8 bits, 12 bits, and 16 bits. The higher the quantization bit, the greater the dynamic range of the signal, and the closer the digitized audio signal is to the original signal, but the larger the storage space required;

[0014] Linear prediction analysis: A set of prediction coefficients is solved by minimizing the mean square error between the actual speech samples and the linear prediction samples.

[0015] Cepstrum analysis: Since a frame of speech signal is equal to the convolution of the excitation source and the impulse response of the linear time-invariant system, in order to study the excitation and vocal tract characteristics separately and focus on analyzing the impulse response related to the characteristics of the system itself, it is necessary to perform a similar analysis on the speech signal, namely, cepstrum analysis.

[0016] According to the above technical solution, the signal transmission device is one or more of a router, a data cable and Bluetooth;

[0017] The signal transmission device encrypts the voice during signal transmission and generates a key at the same time, transmits the key to a predetermined account through a signal, and directly decrypts the voice data after it is converted into a digital quantity;

[0018] The cloud information base is a cloud database that is connected to the network map information, updated regularly, and ensures normal data transmission;

[0019] The comparison module compares the data of the collection device, extracts similar words from the comparison, compares them, lists multiple results, and outputs them through the output device, so as to facilitate the collector to compare and select information;

[0020] The output module is a touch screen, which outputs and displays the output results of the comparison module, thereby ensuring the display of data.

[0021] According to the above technical solution, the manual collection includes the following steps:

[0022] S1. Preliminary preparation: collect basic data materials and mark them;

[0023] S2. Voice collection: Voice collection is performed through external equipment to ensure normal recording and playback;

[0024] S3. Collect data information: receive and interpret voice, and extract geographic information of basic materials;

[0025] S4. Output result: report the result to the voice sender to determine the accuracy of the information.

[0026] According to the above technical solution, the basic materials in step S1 include route names, place names, superscripts and subscripts, and kilometer marks;

[0027] In step S2, the voice collection is recorded and saved using a recorder, an APP and a computer hard disk.

[0028] According to the above technical solution, in step S3: when storing the basic data of the collected route, if there is no such route, the basic data of the collector needs to be updated in time. After starting the collection, through GPS data analysis, the number of satellites in use and the positioning status are observed. When working normally, the effective positioning is displayed. Click to collect the information point information, enter the route code, information point attributes, and information point name, and finally click to collect. The collected data is saved in the collection information management.

[0029] According to the above technical solution, in step S4, the output result is reported, and if incorrect geographic information is found, steps S1, S2 and S3 are re-executed to form a cycle.

[0030] According to the above technical solution, the automatic collection and manual collection adopt selective judgment, and the data information in the automatic collection and manual collection is common.

[0031] According to the above technical solution, a system for collecting geographic information based on voice input is characterized in that it is a system made according to a method for collecting geographic information based on voice input.

[0032] Compared with the prior art, the present invention has the following beneficial effects: the present invention has a scientific and reasonable structure and is safe and convenient to use:

[0033] 1. Through automatic and manual collection, it is convenient to collect data in different environments and on different sites, thus realizing the convenience of geographic information collection and achieving local appropriate operations, which greatly facilitates the convenience of operators and collectors.

[0034] 2. Through the collection device, signal transmission device, cloud information database, comparison module and output module, normal voice input and geographic information collection are realized. Through normal voice collection, it is then processed to improve the accuracy of the voice. Finally, through comparison, multiple options are listed, which is convenient for the operator to choose and realizes diversification.

[0035] 3. The aerial photography device can be used to collect information about the local geographical environment, which is convenient for real-time updating. The accuracy of geographical information collection can be improved through normal comparison. The input device can facilitate manual input of geographical information, and manual input can be achieved when it is not convenient to speak.

[0036] 4. Normal loading of geographic information during manual collection facilitates direct reading in the later stage and voice conversion. When storing the basic data of the collected route, if there is no such route, the basic data of the collector is updated in time to avoid errors.
