In order to realize the integration of digital technology and traditional culture, and to explore the innovation path of digital art while carrying out cultural inheritance, this paper carries out computer-aided creation of Chinese paintings by means of computer-aided creation technology. Comprehensively utilizing the region growth algorithm, line drawing intelligent generation model and digital painting virtual pigment model and other computer-assisted methods for the creation of Chinese paintings, followed by objective and subjective evaluation of the creation effect. The model in this paper has the maximum values of recall, precision, mAP, PSNR, SSIM, and the minimum values of LPIPS and FID on both Scene and People datasets, and the optimal effect is obtained on both datasets. The Chinese paintings created by the method of this paper received an overall subjective evaluation of 4.34, with the scores of the primary indexes exceeding 4.25 and the scores of the secondary indexes not less than 4.15, and the viewers have a better view of the Chinese paintings created by the computer-aided creation method of this paper.
