The traditional paper-based sketch of external house survey can not be processed directly by the computer. And the separation of internal and external businesses is inefficient and error-prone. Considering the above problems, the method of generating sketch by touch function is studied firstly. The system automatically generates the regular house graphic which is consistent with the actual situation based on the sketch. Then, the contour tracking algorithm based on vector graphics is studied, and the horizontal and vertical compound linked lists are designed to build dimension chain dynamically, which realizes the construction of sketch constraints and automatic parametric redrawing. In this way, the automatic calculation of the house area, the automatic correlation of graphic and data and the automatic generation of reports are realized, and the results can be imported directly into the computer. Finally, a software system that supports the above functions is developed in the Android platform, and the effectiveness of the aforementioned algorithm is verified.
