在基于2维草图检索3维模型的研究中，通常没有结合人的知识。
In the research of 3d model retrieval based 2d sketch, people's knowledge is not usually adopted.
图4显示了该查询检索到的图像具有与图3内的草图类似的形状和颜色。
Figure 4 shows the images retrieved by the query having similar shapes and colors to those of the sketch in Figure 3.
实验结果表明，该方法能提高检索精度，因此可应用在2维草图查询方式的3维模型检索中。
Experiments show that the method can improve the precision of retrieval, and thus the proposed approach can be applied to interactive 3d shape retrieval based 2d sketch.
