Idea for question A: Image recognition technology idea model code for fruit picking robots
Don’t think this question is difficult. Identifying apples is very simple. First, extract the R matrix pixel values and set a threshold for binarization. There will definitely be noise after binarization. You need to write some filter matrices to filter them. Then directly identify the position of the circle through the im findcircles function. Apples are generally rounder, so it can be implemented through this function. Machine learning algorithms are not used at all. The accuracy may be very low, and the pixels of the image are very low. The color blocks are also more prominent. •You must use morphological methods to reduce noise. Other methods can just add up the number of pages.
The first and second questions are about the apple’s confidence. The third question requires the apple’s maturity, which is actually the amount of light pigment. The specific maturity level can be divided by unsupervised clustering. The fourth question is to find the area. The im findcircles function can locate the circle and calculate the radius. You can directly calculate the approximate area of the apple based on this data
Other fruits can be expanded and analyzed to verify the model. reliability
Idea for question B: Microclimate regulations in glass greenhouses
A simple understanding is that the temperature in the room has a heat conduction process, but there is an acceleration. However, question I I requires thermal convection to be considered. As the distance increases, the wind speed will gradually attenuate due to air resistance or crop resistance. Among them, the air outlet is the lowest. , the greater the crop resistance received. The first three questions are about the calculation of fixed value parameters. The fourth question requires optimization algorithm to learn the number, specifications and location layout of the air outlets. This simulation has a corresponding physical module in the comsol software. You can also try it. Some simulation diagrams are shown. Each module of this software has a corresponding model. If you really can’t find the literature or are unsure about the formula, you can use comsol software to find it on it.
