TECHNICAL FIELD

[0001] The utility model belongs to the field of tomato cultivation technology, and specifically relates to a sugar content detection device for tomato cultivation. BACKGROUND

[0002] Spectral imaging technology combines image and spectroscopy, and has the advantages of rapidity, non-damage, non-chemical composition and simple operation in application, and the advantage of multispectral imaging over ordinary imaging lies in that multispectral imaging not only includes the spectrum of red light, blue light and green light, but also includes the spectrum in the range of near-infrared and ultraviolet. The sugar content of tomatoes can be obtained by using the multispectral imaging equipment to obtain multispectral tomato images and combining a learning algorithm.

[0003] However, the following technical problems still exist: 1. The relative position of the camera of the multispectral imaging instrument and the photographed object is fixed, and it cannot well adapt to samples of different sizes and shapes. Since large samples are relatively close to the camera, the details are clear, but small samples are relatively far from the camera due to their small size, and the details are relatively unclear; 2. For some uneven samples or samples with a large photographed surface, the light source is irradiated in a fixed direction, which may cause certain shadows or reflections, affecting the experimental results.

[0004] Therefore, there is a need for a sugar content detection device for tomato cultivation to solve the problems of unclear tomato photo shooting and the inability to irradiate some positions of the tomato, thereby affecting the accuracy of the detection results in the prior art.
