处理数据

The system utilized four laser scanners along lengthwise direction of the log. Data are obtained in every ten degrees when log is turning, in each cross section, 36 data are obtained. Then the data obtained were processed and an outline of the cross section of the log was developed on computer screen. Afterwards, the largest inscribed circles for log cross sections were determined according to the principle that three points can determine a circle. Secondly, the points located on the cross sections were linked up along some log generative in order to simulate the three-dimension log outline. At last the largest right circular cylinder were optimized and the optimum turning center was determined by means of projective theory.

具体作法是：在木段长度方向均匀设置四个激光传感器，当木段旋转时，起动激光传感器，进行数据采集，每隔10~0扫描一个点，在各横断面圆周上共采集36个点的数据，由计算机处理采集的数据，并绘制出原木横断面的几何图形，再根据三点定圆的原理，确定出最大内接圆；其次，模拟原木三维廓形，即将原木相邻横断面上离散点沿着母线方向连线，由计算机分析处理，绘制原木三维廓形；最后，采用投影法，优化出原木最大内接圆柱体，并确定原木回转中心线。

This paper presents a design method of an off-line portable scanner, which can be used without computer. We discuss the system based on a synchronous Digital Signal Processor with multicenter, which is used to gather data with high speed. TIs TMS320VC5402 is a sixteen-bit fix processor, and we make it the core of our control system. Because it can not only handle data with high speed but also manipulate the data by abundant arithmetic/logic operations and determine the results of processing which can be output quickly as images.

The title and bill of material in engineering drawings are important data source for product data integrated management. In order to reuse the CAD data, the paper presents an effective method for extracting part information from existing engineering drawings. Through analyzing the format of title and bill of material, several shape-position characteristics of tables are summed up from the view of macro-layout and microstructure. A new method to automatically extracting drawing information based on cell-grid and feature-point is proposed along with its algorithm principle and implementation steps. A software package based on the method mentioned above is developed and used in practice.
