Abstract: The invention introduces a system for acquiring data on poultry body size, utilizing a baseplate for immobilization. After positioning the poultry, the system adjusts a fixing device on a rod to secure the poultry's knee joints using a fixing clip, thereby stabilizing the poultry's body. A 3D laser scanning lens then conducts comprehensive 3D scanning of the poultry's entire body, transmitting the data to a 3D microcomputer which generates an optimal dynamic model image. This microcomputer organizes and analyzes data from the model using a computer algorithm, ultimately displaying the poultry's body size indices on the 3D microcomputer's display. This method circumvents inaccuracies common with traditional tools like electronic scales, enhancing the speed and precision of poultry body composition data collection.
