ECA-GG02 Image Crown Analyzer Introduction: The ECA-GG02 image canopy analyzer is widely used in research and teaching related to cultivation, breeding, plant population comparison and development in the fields of agriculture, horticulture, and forestry. It measures and analyzes the light exposure of crops, fruit trees, and forests in the canopy. Can calculate the solar direct light transmittance, sky scattered light transmittance, canopy extinction coefficient, leaf area index, and average leaf inclination angle of plant canopies. The ECA-GG02 image canopy analyzer adopts the principle of correlation between canopy porosity and canopy structure. It is based on the Beer's law of light passing through a medium to weaken. Under a series of assumptions defined for the plant canopy, a semi theoretical and semi empirical formula is used to calculate the canopy structural parameters through the measurement of canopy porosity. The method used is to analyze and measure the porosity of the canopy based on the images of the hemisphere below the canopy. characteristic 1. Non destructive determination of canopy structure 2. Can measure the photosynthetic effective radiation (PAR) inside and outside the canopy 3. Handheld universal joint automatic horizontal adjustment probe, 4. A portable laptop can help you select the right sampling points and make real-time decisions on image choices 5. Powered by computer batteries, it is extremely lightweight and easy to observe, especially suitable for completing heavy observation tasks in the field 6. Image analysis software can define image analysis areas arbitrarily (zenith angle can be divided into 10 areas, azimuth angle can be divided into 10 areas). When conducting regional analysis on different directions of the canopy, it is possible to arbitrarily shield the terrain and unreasonable canopy parts (such as missing plants, edge row problems, etc.). The selection of starting and ending angles for different zenith angles can avoid canopy pore conditions that do not meet the calculation criteria for the canopy structure parameters 7. The measurement point images can be directly displayed on the computer through a USB interface, allowing for real-time observation of the images in the field, selecting reasonable measurement points, and storing the images. 8. On a hemispherical image, the visual motion trajectory of the sun can be designed for any location and time, as well as the lighting conditions at any time within the canopy. Technical parameters: 1. Lens angle: 150 ° (or user selected 180 ° lens). Unless the user has special needs, the 180 ° fisheye lens can be adjusted The prerequisite conditions assumed by the principles and methods of porosity measurement are often not suitable for canopy structure analysis And uneconomical. 2. Resolution: 768 × 494pix 3. Measurement range: The zenith angle can be divided into ten regions from 0 ° to 75 ° (150 ° fisheye lens), and the azimuth angle can also be divided into ten regions at 360 °. 4. PAR induction range: Induction spectrum 400-700nm. Measurement range: 0-2700 μ Mol/m2 • s 5. Analysis software: Professional ECA-GC02 software. 6. Display and memory: Based on laptop (self configured). 7. Battery: Computer battery. 8. Transmission interface: USB 9. Working temperature: 0-55 ℃
