In order to realize the non-contact positioning of targets in narrow, dimly-lit and enclosed space, it is proposed to use multi-slit raster imaging with different spacing between the slits in this text.Linear CCD image sensors are used to receive optical signals, and then convert the optical signals into electrical signals for output.The mother board and daughter board are constructed according to the position of target and the corresponding output data of the sensor.After algorithm analysis and template matching, we obtain the target's two-dimensional coordinate position information.This text simulates the actual measurement environment and device, builds a mathematical model and simulates with MATLAB.The result shows that it can obtain the two-dimensional coordinate position information of the target accurately through the method, it is verified that the method is feasible on the basis of theory.%为了实现对狭小、光线昏暗的封闭空间的目标进行非接触式定位, 本文拟采用多狭缝光栅成像, 狭缝间距不等, 采用线阵CCD图像传感器接收光信号并转换为电信号输出, 根据目标所在位置以及传感器相应的输出数据构造母板和子板, 经过算法分析以及模板匹配从而得到目标的二维坐标位置信息.本文模拟实际测量环境与器件, 构建数学模型, 并通过MATLAB进行仿真.结果表明该方法可以准确地得到目标的二维坐标位置信息, 从而验证了该方法在理论上是具有可行性的.
