| 摘 要： | 车载平台倾斜对光测设备的测角精度影响较大，为了消除这种影响，提出了采用编码器测倾装置测量平台倾斜角度并进行事后修正的方法。首先，分析了光测设备工作时，车载平台倾斜的原因；其次，采用编码器测倾装置测量平台倾斜角度，并将测得的数据传送到控制计算机；最后，根据车载光测设备静止和工作时的不同特点，对存储的数据进行滑动均值滤波处理和滑动加权均值滤波处理，将处理后的数据用于事后测角误差的修正。实验结果表明，将编码器测倾装置测得的数据进行滤波处理后，减小了噪声对倾斜数据的影响，提高了数据的可使用性，为下一步车载光测设备测角误差修正模型的建立奠定了基础。

| Abstract: | The tilt of vehicular platform will have the biggish influence on the angle measuring precision of optical measurement equipment, in order to eliminate this effect, the encoder measurement of tilt was proposed to measure the tilting angle of vehicular platform, and correct the angle measuring error afterwards. Firstly, the reasons of tilt of vehicular platform was analyzed when the optical measurement equipment was working. Secondly, the encoder measurement of tilt was used to measure the tilting angle of vehicular platform, and send the data to the master computer. Finally, according to the different characteristics when the optical measurement equipment was stationary and working, the storage data was carried to process through sliding mean filtering and sliding weighted mean filtering, the processed data was used to correct the angle measuring error afterwards. Experimental results show that the data through filter by the encoder measurement of tilt, reducing the impact by noise to the tilted data, improve the usability of data. It establishes foundation for the next of angle-measuring error emendation model of the optical measurement equipment. |
