Acquisition device for crop multispectral images applied to agricultural robots

Abstract

The present invention provides a crop multispectral image acquisition device applied to an agricultural robot, comprising: a base, a camera, a filter switching part, a limiting part and a preset number of filters; the base is fixedly connected to the camera, preset A number of filters are fixed on the filter switching part, the filter switching part is connected to the base and the filter switching part can move relative to the base, the limiting part includes a first part and a second part, and the first part can move relative to the second part. The two parts move and can be prevented from moving by the second part, the first part is fixedly connected to the filter switching part, the second part is fixedly connected to the base, and the filter is fixed to the filter switching part; when using the acquisition device , switch the filter covering the front of the camera lens in real time according to needs, and can collect spectral images of multiple bands in a single field of view, and realize the complete presentation of spectral images of multiple bands to the target area, which is conducive to improving the accuracy of the target area. accuracy of information obtained.

Description

technical field [0001] The invention relates to the technical field of machine vision, and more particularly, to a device for collecting multispectral images of crops applied to agricultural robots. Background technique [0002] With the development of agricultural automation in China, robots have been more and more widely used in agriculture. Among them, using machine vision technology to collect crop information with robots is also an important aspect of the application of robots in agriculture. [0003] In the agricultural environment, the stems, leaves and fruits of crops are complex and diverse, and have similar color systems in the visible light band, which poses a huge challenge for robots to accurately obtain visual information of different tissues of crops. However, due to the differences in the internal micro-tissue components (carbohydrates, water, fibers, etc.) of different tissues of plants, the reflection characteristics of different parts of plants such as ste...

Problems solved by technology

[0004] At present, the use of robots to collect information on crops is mainly to collect images of the full or single band of visible light of crops through cameras, and intelligently process the collected spectral images to obtain the required information. There is stray light interference or limited single-band information. problems that affect the accuracy of information acquisition in the target area
