Description
Technical Field
[0001] The present invention relates to the technical field of agricultural monitoring equipment, and in particular to a crop inspection robot and method with adaptive supplementary lighting. Background Art
[0002] In modern agricultural production, the development of precision agriculture is crucial to improving crop yield and quality. Spectral imaging technology is widely used to monitor crop growth status, but in greenhouse environments, changes in light conditions, humidity, and temperature pose challenges to traditional equipment. In modern facility agricultural production, precise monitoring of greenhouse crop growth status faces the following key challenges.
[0003] The lighting environment in a greenhouse has significant dynamic characteristics, and its light intensity fluctuates within three orders of magnitude (10^2-10^5 lux). The main influencing factors include: (1) natural light fluctuations: affected by weather conditions, the instantaneous light intensity can vary by ±15,000 lux; (2) facility structure influence: the attenuation of greenhouse film transmittance and the shading effect of plant canopy can cause local light attenuation of 40% to 60%; (3) environmental coupling effect: when the relative humidity is >80%, it causes light path scattering, and the temperature gradient causes the sensor response to drift by about ±5%.
[0004] When using traditional monitoring systems, the system adopts a fixed gain mode, which makes it difficult to adapt to the wide dynamic range lighting conditions of 10^2-10^5 lux. It lacks a real-time environmental feedback mechanism (lack of closed-loop control capabilities to dynamically perceive ambient light and automatically adjust), and lacks effective compensation for the temperature and humidity coupling effect (light path scattering when humidity > 80%). The single-point fixed acquisition method cannot reflect the vertical gradient distribution characteristics of environmental parameters, the spatial coverage is seriously insufficient, the sampling frequency is low (typical value ≥ 1 day / time), it is difficult to capture the dynamic changes of environmental parameters, the spatial resolution is limited, and it is impossible to build an accurate three-dimensional environmental field model. In addition, the traditional agricultural inspection model relies entirely on manual operation and cannot achieve continuous monitoring. At the same time, there is a subjective judgment bias in manual observation, resulting in insufficient detection accuracy. A single inspection operation takes up to 4-6 hours, resulting in high labor intensity and a lack of unified environmental parameter quantification standards.
[0005] Therefore, we propose a crop inspection robot and method with adaptive supplementary lighting to solve the above problems. Summary of the Invention
