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。

In the computer simulation aspect, following work has been down:At first, the Wolfgang Schreiner's model is employed and extended to a new computer arteriole optimal growing model. Many new algorithms are described, such as signal tracing, resistance calculating, resistance balancing and flow balancing. With these algorithms and methods, the arteriole networks can be grown successfully on microcomputer.Secondly, a growing-network ordering method, which is called auto-centripetal ordering method of the growing networks, can be employed to order the growing networks to calculate the average parameters of the networks in level series.

This high-speed element is used as a "scratch pad" to temporarily store data and instructions that are likely to be retrieved many times during processing.Processing speed can thus be improved.Data may be transferred automatically between the buffer and primary storage so that the buffer is usually invisible to the application programmer.Once found only in large systems,cache memory is now avaliable in some of the tiny microprocessor chips used in personal computers.

该高速存储器可用作"便笺"，暂时存放那些在处理中很可能多次查询的数据和指令，这样可提高处理速度，由于数据在这个高速缓冲器和主存之间可自动传输，所以该告诉缓冲存储器对应用程序员来讲通常是不可见的，过去只在较大的计算机系统中才有的高速缓冲存储器，现在在一些用于个人计算机系统的很小的微处理器芯片中也采用了。
