摘要：Vexcel announced their first large format aerial camera UltracamD(UCD) at ASPRS Anchorage in May 2003. Three years later UltracamX(UCX) successor model of UCD is announced at ASPRS Reno. In June 2004 PASCO Corporation introduced first UCD and continuously introduced second UCD in December. Since then PASCO has carried out many large scale mapping projects and also orthophoto projects up to now. The average project number is nearly 100 per year and almost 90,000 images are processed. In April 2007 PASCO introduced two UCXs and now it is also used for high resolution digital image acquisition. All of our UCD and UCX are integrated with APPLANIX POS AV310. In some case, for instance small scale orthophoto projects, direct georeferencing without adjustment is performed. The large format aerial frame digital camera VEXCEL UCD, UCX and INTERGRAPH DMC is now getting popular in Japan. At least more than 15 digital frame cameras are operated by several mapping companies. The Japanese mapping standard for public mapping which includes rules about large format aerial digital frame camera was published in April 2008. Currently, various investigations and research projects about geometric accuracy are carried out and systematic error which remained after laboratory calibration is also analysed. In this paper we report systematic error situation about UCD and result of geometric accuracy investigations
