摘　　要：传感器检校是车载多传感器集成系统中不可缺少的重要环节。介绍了一种线阵相机的数学标定方法,根据该方法设计了相关的检校设备及检校坐标系。通过对不同条件下的试验数据对比,获取最佳的实验条件和该方法所需的基本参数,并采集最佳试验条件下的试验数据,通过对数据进行处理得到投影中心坐标,对可能影响检测结果的多种实验因素进行了分析,将受这些因素影响较小的数据作为有效数据来解算最终的实验结果,可以得到较精确的结果。Sensors calibration is the very important part of vehicle-borne multi-sensor integration system.A mathematical calibration method of single-scanline camera is introduced.According to this calibration method,the correlative calibration equipment needed by the method and the calibration frame are designed and explained.The optimal experiment conditions and parameters needed by the method are gotten by comparing the data in different conditions,then the experiment data having the best conditions and parameters is gotten.Although the coordinates of central projection can be gotten by dealing with the gotten data,it is not the final result.Because the calibration results may be interfered by some experiment factors,the factors must be found and analyzed in order to get the best data.At last the valid data slightly affected by the adverse factors is gotten and used to calculate the final results.
