Due to the rapid information process, the amount of product characteristic data increases exponentially. In the field of product characteristic display, traditional technology can no longer meet people's needs. In this paper, a threedimensional projection system based on stereo projection is designed to realize three-dimensional real-time projection of product characteristic data, and the three-dimensional model and product characteristics are superimposed into the holographic scene by constructing a three-dimensional model of the product. Form a display form combining static and dynamic. The representation of product characteristic data is upgraded from a simple plane form to a three-dimensional form combined with a three-dimensional model, and the relationship between product characteristics and target attitude changes is intuitively revealed, significantly improving people's understanding of product characteristic data.
