(利用GIF_LZW算法实现的)网络图片传输 技术特点 ~~~~~~~~ 一、使用TCP协议传输数据。理由:稳定性好。 二、使用字节数据流进行传输,理由: A:VB的String存在自动Unicode转换问题,影响速度; B:可以直接发送8位字节数据,不需要使用Base64编码,从而减少了编码时间。 三、使用GIF-LZW压缩算法压缩图像。理由: A:行程编码、Huffman压缩算法压缩率太低; B:JPEG压缩算法需要太多位运算,且运算量大(有专门MMX优化算法),不利于VB实现; C:GIF-LZW压缩算法压缩率较好,且我已想出VB语法下高效GIF-LZW压缩/解压算法。 四、使用“有序抖动”算法进行 色彩量化。理由:“有序抖动”处理的结果具有一定规律性,有助于LZW类算法压缩。-(using GIF_LZW algorithm) picture transmission network ~~~~~~~~ a technical features, the use of TCP to transmit data. Reason : good stability. Two, the use of byte data stream for transmission, reasons : A : VB String exist automatically Unicode conversion, the impact speed; B : can directly send eight bytes of data and do not need to use Base64 encoding, thereby reducing the coding time. 3, the use of GIF- LZW compression algorithm for image compression. Reason : A : itinerary coding, Huffman compression algorithm compression rate is too low; B : JPEG compression algorithm needs much-bit computing, and large amount of computation (with MMX spe

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.)
