Example Embodiment
[0026] The present invention has universality for non-destructive testing of tea quality. However, due to the many types of tea, the present invention only gives an implementation example for the quality level testing of roasted green tea. For testing other teas, please refer to the method of this implementation example, specifically for By establishing a new discriminant model based on the quality index of the tea samples tested, the quality level of the tea samples can be tested.
[0027] Refer to the implementation example steps figure 1 , See example implementation device figure 2 . First select a batch of tea samples (generally more than 50 samples for each grade) to build a model, use a detection device based on near-infrared spectroscopy and machine vision technology to perform spectrum and image collection and scanning on the tea samples, and transmit the collected data to In the computer. The comprehensive quality level of fried green tea is determined by the results of ...
