Embodiment 1

[0067] This embodiment provides a method for customizing filter components, such as figure 1 As shown, the customization method includes the following steps:

[0068] Step 101, collecting index data of ecological indicators.

[0069] Among them, the indicator data of ecological indicators can be selected according to needs, figure 2 Several specific types of ecological indicators are shown, such as leaf area index, canopy cover, total phosphorus, ammonia nitrogen, chemical oxygen demand, and so on.

[0070] It should be understood that in this embodiment, corresponding filtering components can be customized according to the collected index data of ecological indicators. Specifically, the filtering component can be a filtering component of a photographing device, such as a multispectral camera.

[0071] Step 102, collecting the spectral data of the carrier of the ecological index.

[0072] Specifically, the collection of spectral data can be based on the selection of spectr...

Embodiment 2

[0139] This embodiment provides a filter module, which includes several filter components.

[0140] Wherein, the filter components in this embodiment include filter components customized according to the method for customizing filter components in Embodiment 1.

[0141] Specifically, according to different ecological indicators to be observed, the grouping band and grouping bandwidth can be calculated in a targeted manner, so as to customize the filter components corresponding to the ecological indicators in a targeted manner.

[0142] When it is necessary to observe specific ecological indicators, select the filter components corresponding to the ecological indicators from the filter module to observe. For example, when performing remote sensing water quality monitoring, when it is necessary to observe the ecological indicators of oxygen demand and ammonia nitrogen, the The three wavelengths customized by the customization method in Example 1 are 640nm, 675nm and 705nm respec...

Embodiment 3

[0145] This embodiment provides a grouping method of a multispectral camera, the multispectral camera includes the filter module in Embodiment 2, such as Figure 13 As shown, the matching method includes the following steps:

[0146] Step 301, obtaining the ecological indicators to be monitored;

[0147] Step 302, obtaining the filtering components corresponding to the ecological indicators from the filtering module;

[0148] Step 303, monitor through the filtering component.

[0149] In the grouping method of this embodiment, the corresponding customized filter components can be selected for observation according to the ecological indicators to be monitored, so that the filter components are more targeted and the accuracy of the monitored data is higher.

Abstract

The invention discloses a customization method of a filtering component, a filtering module, a matching method, equipment and a medium. The customization method comprises the following steps: acquiring index data of ecological indexes; collecting spectral data of the carriers of the ecological indexes; determining a matching wave band according to the index data and the spectral data; determining a matching bandwidth according to the matching wave band; and customizing the filtering component according to the matching wave band and the matching bandwidth. According to the invention, different filtering components can be customized according to different observation purposes, especially in the observation field of ecological remote sensing, different filtering components can be customized according to different ecological indexes, when different filtering components are customized, two kinds of data of wave band and bandwidth are considered at the same time, and the pertinence and the accuracy of the ecological remote sensing observation equipment are improved.

Description

technical field [0001] The invention relates to the field of natural resource monitoring, in particular to a method for customizing filter components, a filter module, a grouping method, equipment and media. Background technique [0002] At present, the research on natural resources is gradually shifting from the macroscopic to the microscopic, and the number of natural resource investigation elements is also increasing. [0003] It is a common choice to monitor natural resources through hyperspectral cameras. Hyperspectral cameras can simultaneously acquire data of more than hundreds of bands, but most of these data are redundant data that are useless for target observation. The band selection method for observation tasks is mainly used in the post-processing of hyperspectral data, which is a processing method for redundant data. However, this method does not consider the bandwidth of the band during the specific observation, and has no effect on the production of hyperspec...
