Problems solved by technology

[0007] However, according to the conventional technology, there is a problem that it is difficult to obtain the planting area of ​​the crops planted in the field.
For example, sometimes a path for prevention and control work is set up in the field. If the entire area of ​​the field is simply used as the planting area of ​​crops, the area o...

Embodiment approach 1

[0042] Figure 1 ~ Figure 3 It is an explanatory diagram showing an example of the calculation method according to the first embodiment. exist Figure 1 ~ Figure 3 Here, the calculation device 101 is a computer that calculates the distance of the work interval of the agricultural work performed by the agricultural machine M. Here, the agricultural machine M refers to an agricultural machine used for agricultural work. The agricultural machine M has traveling devices such as wheels or crawlers. Examples of the agricultural machine M include an agricultural tractor, a field cultivator, a rice transplanter, a combine harvester, and a sprayer.

[0043] In addition, the agricultural machine M is equipped with a position measurement device 102 for measuring the position of the agricultural machine M. As shown in FIG. The position measurement device 102 measures the position of its own device at constant time intervals such as several seconds, tens of seconds, or minutes. In add...

Embodiment approach 2

[0089] Next, the system 400 according to Embodiment 2 will be described. In Embodiment 2, a case where the calculation device 101 according to Embodiment 1 is applied to the work area calculation device 401 in the system 400 will be described. In addition, the agricultural machine M corresponds to any one of the agricultural machines M1 to MF described later.

[0090] (Example of system configuration of system 400)

[0091] Figure 4 It is an explanatory diagram showing an example of the system configuration of the system 400 . exist Figure 4 Herein, the system 400 includes a working area calculating device 401 and a plurality of position measuring devices 102 (three in the drawing). In the system 400 , the work area calculation device 401 and the position measurement device 102 are connected via a wired or wireless network 410 . The network 410 is, for example, the Internet, a LAN (Local Area Network), a WAN (Wide Area Network), or the like.

[0092] Here, the working ...

Embodiment approach 3

[0229] Next, the working area calculation device 401 according to Embodiment 3 will be described. In Embodiment 3, a case will be described in which position data indicating a point where the agricultural machine M stops and position data indicating points outside the target field are deleted from the position data D1 to Dn indicating the movement trajectory of the agricultural machine M. Note that illustration and description of the same points as those described in Embodiment 2 are omitted.

[0230] (Example of Functional Configuration of Work Area Calculation Device 401)

[0231] First, a specific functional configuration example of the acquisition unit 901 of the working area calculation device 401 according to Embodiment 3 will be described. Figure 19 It is a block diagram showing a specific functional configuration example of the acquisition unit 901 of the working area calculation device 401 . exist Figure 19 Among them, the acquisition unit 901 of the operation ar...

Abstract

A calculation method includes obtaining a temporal sequence of position data representing movement loci of an agricultural machine; extracting from among the obtained sequence of position data, a set of position data representing an interval among the movement loci of the agricultural machine and in which slopes of segments connecting two points represented by consecutive position data among the sequence of position data are consecutively within a given range; and calculating based on the extracted set of position data representing the interval, a length of a work interval of agricultural work performed by the agricultural machine. The calculation method is executed by a computer.

Description

technical field [0001] The present invention relates to a calculation method, a calculation program and a calculation device. Background technique [0002] In agriculture, it is important to predict the yield of crops grown in a field in order to judge the expected sales of crops. In addition, the manager of the farm has an urgent desire to grasp the workload of the agricultural work performed by the operator on the field in order to estimate the operator's return. [0003] As elements for estimating the yield of crops and the workload of agricultural work, there is, for example, the planting area of ​​crops grown in a field. A farm manager can determine the yield of crops based on, for example, the planting area of ​​the crops and the standard yield per unit area of ​​the crops. Also, the manager of the farm can judge the workload of the daily agricultural work based on, for example, the planting area of ​​the crops grown in one day. [0004] As a related prior art, ther...
