多軸遙控飛行器顧名思義,就是三軸以上,包括四軸、六軸、八軸或更多軸的飛行載具。由於操控十分簡單,且價格日趨低廉,目前已廣泛應用於空中攝影。
多軸遙控飛行器的前身為無人飛機,由於價格十分昂貴,早期多用於偵察或轟炸等軍事用途。隨著飛控技術、衛星定位、無線影像傳輸、遙控技術日益進步,多軸無線遙控飛行器已漸漸變成消費型商品,價格從數萬元的普及機種到數十萬元的專業機種,琳瑯滿目,應有盡有。
機場捷運自民國95年開工以後,為紀錄施工期間的工程施工情形及地景變化,高鐵局每年均由同仁搭乘載人直昇機進行空中拍攝任務。由於載人直昇機的租賃價格十分昂貴,易受天候影響及航管限制,且不能太靠進拍攝目標物,故每年以執行一次為原則。為克服載人直昇機的種種限制,本局於民國103年首度採用多軸遙控飛行器執行機場捷運工程拍攝工作,實施至今,成果十分豐碩。究其原因,概述如下:
1. 突破制高點的限制:傳統相機拍照時最大的障礙為制高點的限制。多軸遙控飛行器因可垂直起降,飛行高度及距離均可達1,000公尺左右,故執行拍照任務時,可自由抵達所要高度及位置進行拍攝,不受任何限制。
2.具備穩定性極高的雲台:傳統相機是靠手持或腳架穩定機身進行拍攝,而多軸遙控飛行器則是仰賴穩定性極高的雲台進行拍攝,雲台由電腦及陀螺儀控制,可完全吸收飛行器的震動及側風造成的晃動,以攝得效果極佳的照片或影片。
3.較不受天候及航管的限制:由於多軸遙控飛行器的飛行成本不高,所以對於天候或能見度的要求不是很高,只要任務需要,除非是下雨,原則上隨時都可出機執行任務。且飛行較不受航管的限制。

Multi-axis vehicles are aerial vehicles consisting of three, four, six, eight or more axes. Since controlling the apparatus is very simple, and the price has become more affordable, it has been widely used in aerial photography. The multi-axis vehicle is an extended development of an unmanned aerial vehicle which was expensive and used mostly in reconnaissance or bombing and other military purposes. With the increasing progress of flight control technology, satellite positioning, wireless video transmission and remote control technology, the wireless multi-axis remote piloted vehicle (RPV) has gradually become consumer goods. Prices vary from a few thousand for universal models to several hundred thousand dollars for professional models. There are miscellaneous products with any type you need.
Since the groundbreaking of TIAA MRT Project in 2006, BOHSR has annually sent colleagues aboard manned helicopters to execute the aerial photography mission to record engineering situation and landscape changes during construction period. Since the rental price of a manned helicopter is very expensive, additionally, it is susceptible to the impact of weather and air traffic restrictions and cannot be too close to the recorded subject, so in principle, the mission is to be performed only once a year. To overcome the limitations of a manned helicopter, BOHSR adopted multi-axis RPV for the first time in 2014 to film the TIAA MRT construction. Since the implementation, the outcomes are very fruitful. The reasons are outlined as follows:
1.Breakthrough for commanding height restrictions: the biggest obstacle for traditional camera is the commanding height restrictions. Due to capabilities of vertical takeoff and landing (VTOL) and reaching altitude and distance of about 1,000 meters, the multi-axis RPV can arrive at any height and position without any restrictions when executing photographing tasks.
2.A high stability cradle head: traditional cameras rely on hand or tripod to stable the camera body during shooting, while multi-axis RPV is highly dependent on the stability of the cradle head. The cradle head is controlled by the computer and gyroscopes and can completely absorb vibration of the RPV during shock and rocking caused by crosswind to capture excellent photos or videos.
3.Less susceptible to weather and air traffic control: as the flight costs for multi-axis RPV are not high and limitations for weather or visibility are relatively low, as long as a task is required, unless it is raining, the RPV should generally be able to perform tasks at any time and should be unrestricted to air traffic control.
