Soybean protein meat three-dimensional quality characteristic and foreign matter detection method based on ultrasonic elastography technology

The invention belongs to the technical field of food detection, and particularly relates to a food quality and foreign matter detection method based on an ultrasonic elastography technology. The method mainly comprises the following steps: acquiring spatial position and volume information of a target detection object; planning a moving track of the linear scanning ultrasonic probe; acquiring and storing elastic ultrasonic information; performing real-time visualization on the two-dimensional elastic ultrasonic information slice; performing three-dimensional reconstruction and visualization on the two-dimensional ultrasonic information; according to the method, the elastic ultrasonic technology is adopted to detect and identify the foreign matters in the soybean protein meat finished product and the soybean protein meat finished product doped with rotten raw materials, so that the quality of the soybean protein meat can be reflected more accurately, and the foreign matters in the soybean protein meat can be po
