- Abstract: Aiming at the problems of tongue diagnosis instruments relying on manual operation,uneven illumination,color distortion and lack of dynamic information,an automated operation black box tongue diagnosis instrument based on machine vision is proposed.This instrument utilizes machine vision technology and image processing algorithms to achieve automatic positioning and automatic acquisition of tongue manifestations.High-resolution camera technology enables the acquisition of 3-second dynamic videos and high-quality static images.The performance test results show that,based on the dual-camera geometric projection calibration algorithm,the average time for tongue recognition is less than 0.15 seconds.The diffuse reflection light source improves the gray uniformity to 76.74%,and the maximum color difference in color reproduction degree is 19,which is better than the industry standard value of 25.The developed tongue diagnosis instrument will promote the objective,efficient and precise acquisition of tongue diagnosis in traditional Chinese medicine.
