Embodiment 1

[0032] figure 1 It is a flow chart of a method for determining the collection parameters of a geographical area provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of determining the collection parameters involved in the information collection work of a geographical area. The method can be implemented by a geographical area The acquisition parameter determination device of the region can be implemented by means of software and / or hardware, and generally can be integrated into equipment such as a computer. Specifically include the following steps:

[0033] S110. Preprocessing the historical collection point data to obtain the collection efficiency of the preset level area.

[0034] Among them, the historical collection point data refers to the basic data source, that is, the collection trajectory data of each collection operation vehicle (hereinafter referred to as "vehicle sky") historical operations every day, and the data can be...

Embodiment 2

[0059] Figure 4 It is a flow chart of a method for determining collection parameters of a geographical area provided by Embodiment 2 of the present invention. This embodiment is optimized on the basis of the above-mentioned embodiments, and "preprocesses historical collection point data to obtain preset "Gathering Efficiency in Level Areas" has been optimized, including the following steps:

[0060] S410. Divide the areas involved in all the collection points in each city into high-speed areas, built-up areas, and non-built-up areas according to the characteristics of preset grade areas.

[0061] Among them, the high-speed zones of all cities are summarized into one high-speed zone.

[0062] Among them, all the high-speed areas of the city are summarized into one scene, and the classification is no longer carried out. The built-up areas of the city are summarized into one scene, and the non-built-up areas of the city are summarized into one scene. Due to the existence of nat...

Embodiment 3

[0073] Figure 7 It is a flow chart of a method for determining the collection parameters of a geographical area provided by Embodiment 3 of the present invention. This embodiment is optimized on the basis of the above-mentioned embodiments, and the undetermined correlation factors of "according to the collection efficiency of the preset grade area Screening to determine effective correlation factors and weight values" has been optimized, specifically including the following steps:

Abstract

The embodiment of the invention discloses a determination method and device for acquisition parameters of a geographic region. The method comprises the steps that historic acquisition point data is preprocessed so as to obtain the acquisition efficiency of a preset rank region; according to the acquisition efficiency of the preset rank region, relevant factors to be determined are screened so as to determine effective relevant factors and weight values; according to the set acquisition efficiency gear, on the basis of the acquisition efficiency, the effective relevant factors and the weight values, a sample region is selected from the geographic region, and the regional rank is determined; according to the similarity of the sample region and the non-sample region of the geographic region, the regional rank of the non-sample region is determined; according to the regional rank, the range value of acquisition parameters of the rank region is determined. Acquisition parameters of different regions are determined to be adopted as the basis of acquisition difficulty quantization, and the reference basis is provided for performance evaluation of justice and equity of acquisition work.

Description

technical field [0001] Embodiments of the present invention relate to big data processing and statistical technologies, and in particular to a method and device for determining acquisition parameters of a geographical area. Background technique [0002] The production of electronic maps requires the collection of outdoor basic geographic data, such as road / panoramic information, which is collected by driving a vehicle equipped with professional collection equipment outdoors, and taking pictures of roads, landmarks and other information. Collection operations will be affected by geographical factors (considered as different cities). Due to the comprehensive differences in natural objective conditions in different cities, the collection efficiency itself will be different. [0003] At present, there is no difference in the collection difficulty of different cities. For example, collection vehicle A: collects 400 kilometers in a similar area / city with wide roads, high grades, f...
