Crop multi-spectral image collection device for agricultural robot

Abstract

The invention provides a crop multi-spectral image collection device for an agricultural robot. The crop multi-spectral image collection device is composed of a pedestal, a camera, a filter piece switching part, a limiting part, and a preset number of filter pieces. The pedestal is fixedly connected with the camera; the preset number of filter pieces are fixed at the filter piece switching part; the filter piece switching part is connected with the pedestal and can move relative to the pedestal. The limiting part consists of a first component and a second component; the first component can move relative to the second component and can be stopped by the second component; the first component s fixedly connected with the filter piece switching part; and the second component is fixedly connected with the pedestal. The filter pieces are fixed at the filter piece switching part. When the image collection device is in use, the filter piece covers the lens of the camera is switched in real time based on needs, so that spectral images with multiple wavebands are collected under a single field of view; and the collected spectral images can display the target region completely, so that the accuracy of information obtaining of the target region is improved.

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
