脉冲激光测距中高精度时间间隔系统设计_田海军
脉冲激光测距系统工作原理即单片机控制激光发 射装置发射占空比一定的激光脉冲,其中一小部分能量 到达接收电路,然后光电探测器将微弱的光脉冲信号变 成电脉冲信号并看作Start信号触发时差测量。激光的 大部分能量在空间中传播,遇到目标物后反射传播到 达接收电路,看作Stop信号结束测量,至此完成时差测 量[2]。TDC?GP22芯片记录Start脉冲到Stop脉冲之间的 时差,用于计算目标物到发射端的距离。(The principle of the pulse laser range finding system is that the single-chip microcomputer controlled laser emission device launches a certain laser pulse, in which a small portion of the energy reaches the receiving circuit, and the photodetector turns the weak light pulse signal into the electric pulse signal and is considered as the time difference measurement of the trigger time of the Start signal. Most of the energy of the laser propagates in the space. After the target, the reflection transmission reaches the receiving circuit, which is regarded as the end of the Stop signal and then completes the time difference measurement [2]. The TDC GP22 chip records the time difference between Start pulse and Stop pulse, which is used to calculate the distance between the target and the transmitter.)

lmap
说明: 天堂的地图配置文件和几个相关的软件
===================
kehuduanmap**.s32
kehuduanmap**.seg
配置文件
配置文件内包含的数据有地图的 安全/战斗区域信息,地图块的拼接与位置信息,建筑物与点缀等内容的拼接与位置
===================
L1MapTool*
地图框架查看器 与 源码
此软件只能查看地图的 安全/战斗区域信息. 关于地图的具体绘制信息并未展示.
因为这个地图肯定是打开了*.s32与*.seg文件 我猜测他就可以直接看到配置文件的明文.
===================
lep.exe
地图预览工具
此工具可以预览极老的某个游戏版本[好像已经失传了]的地图,应该是获取了所有的地图信息后展示出来.
===================(Paradise 1 Game Map Browsing Tool)
