在電力系統(tǒng)中，電網(wǎng)承擔(dān)著輸送分配電能、改變電壓的任務(wù)，它就像人的骨架一樣關(guān)鍵。其中變電站、輸電線路等電網(wǎng)組成部分，則相當(dāng)于骨骼關(guān)節(jié)，經(jīng)常會遭受一些磨損破壞。
對變電站、輸電線路等電網(wǎng)組成部分進行定期巡檢，是每一家供電單位的日常必修課。電網(wǎng)的穩(wěn)定運行與否，不僅影響著我們每一個人的生活，更關(guān)乎國家能源安全。
以往的電力巡檢，需要巡檢工人靠雙腳丈量線路、攀爬桿塔，在高空、烈日、大風(fēng)等考驗下長時間作業(yè)。不僅安全隱患巨大，而且費時費力、效率低下。
2012年左右，無人機開始進入電力巡檢領(lǐng)域，搭載了攝影攝像單元的多軸無人機，成為了巡檢人員的“另一雙眼”。但受到拍攝精度、信息連續(xù)性等技術(shù)限制，當(dāng)時的無人機巡檢仍然無法根除痛點，甚至僅能用于為人工巡檢查漏補缺。
近年來，隨著相關(guān)技術(shù)的發(fā)展，出現(xiàn)了以北科天繪為代表的企業(yè)，借由LiDAR設(shè)備，使得無人機巡檢的精度和效率得到了顯著提升。
國家電網(wǎng)湖南省電力公司，為了驗證激光雷達巡線的效率、精度與便捷度，采用北科天繪的服務(wù)與解決方案，通過激光雷達電力巡線試點項目，成功為電力巡檢工作找到了一條更高效更精準(zhǔn)的實現(xiàn)路徑。
試點項目的測繪區(qū)域，包括位于韶山市的一座100KV變電站及站點延伸出的輸電線路。變電站所在地點地勢低洼、線路密集且有圍墻阻擋，較為的展現(xiàn)了電力巡檢工作的環(huán)境復(fù)雜性。針對此次作業(yè)中的諸多挑戰(zhàn)，北科天繪選擇了專門針對小范圍測區(qū)測量的蜂鳥（Genius）微型無人機LiDAR。
本次項目飛行中蜂鳥搭載了R-Fans-16激光掃描儀
集成R-Fans多線激光掃描儀、慣導(dǎo)測量系統(tǒng)（GNSS/IMU）、計算機控制單元的蜂鳥系統(tǒng)，不僅操作簡單、無需專用場地便可起降，其輕至1.2kg的重量，還讓無人機得以實現(xiàn)更長時間的連續(xù)作業(yè)。
蜂鳥系統(tǒng)的點密度大于200點/㎡，系統(tǒng)測距精度2cm，絕對精度優(yōu)于10cm，足以應(yīng)對變電站電力巡檢的要求。此外、憑借其250m的測距、360°的掃描視場以及320kHz/640kHz的高掃描頻率，實時獲取地形表面的三維空間信息和影像特征，大大提高了航空測繪的掃描效率。
由于測繪范圍中變電站區(qū)域地勢偏低，延伸輸電線路則偏高，蜂鳥系統(tǒng)被設(shè)置在距變電站正上方45m的高度，以5m/s的航速飛行，在無需隨地勢而改變飛行高度的前提下，保證了測繪數(shù)據(jù)的清晰完整。
