Presently there are many methods for 3 - d measurement , among which triangle method is generally adopted for its simple system structure , high speed in measurement and capability for real time processing 目前,三維測量的方法很多,基于激光的直接三角法由于系統(tǒng)結(jié)構(gòu)簡單、測量速度快、且具有實(shí)時(shí)處理能力,被廣泛采用。
The application of the boe in the 3 - d measurement has been investigated in this paper . a 3 - d measurement system is designed and established based on the triangle method , in which boe working as the producer of the structural light 本文研究二元光學(xué)元件( boe )在三維輪廓測量中的應(yīng)用,以boe作為結(jié)構(gòu)光發(fā)生器,設(shè)計(jì)并搭建一套基于三角測量法的三維測量系統(tǒng)。
This paper discusses in detail the range of lon gitude of ascending node of the orbits , by which point and area targets can be c o vered in different conditions by considering the disturbance of the earth shape j2 using a sphere triangle method , and provides a whole analytic expressio n 利用球面三角方法詳細(xì)討論了在考慮地球形狀j2項(xiàng)的攝動(dòng)影響時(shí),各種情況下能覆蓋目標(biāo)點(diǎn)的軌道的升交點(diǎn)經(jīng)度范圍,并將其推廣到對區(qū)域目標(biāo)的覆蓋,給出了完整的解析表達(dá)式。
