[0002] Taro is an important vegetable and food crop with high nutritional and medicinal value. However, it is susceptible to infection by pathogenic bacteria during growth or transportation and storage, leading to internal rot, which affects the quality of taro. Traditional detection of taro is generally by checking the skin of taro, prying the surface of the skin to observe whether there are signs of mold, rot, hardening, dryness, and spots, or by cutting, which is not only inaccurate but also time-consuming and labor-intensive. Therefore, it is important to develop a rapid, accurate, and nondestructive detection method.

[0003] Currently, existing taro internal rot detection methods include visible light and image recognition technology, ultrasonic imaging technology, among which visible light imaging technology can simulate human vision to nondestructively detect the internal taro. Combined with image processing algorithms, the detection of internal foreign matter or rot of taro can be realized. This method has the advantages of simple operation and low cost. Ultrasonic imaging technology uses the propagation characteristics of ultrasonic waves in matter to measure the time, amplitude, and frequency of reflected or transmitted waves, and can obtain the structural information of the internal taro. This method has the advantages of non-contact, no radiation, and low cost. However, the above two methods may be affected in terms of detection accuracy and depth. SUMMARY
