lidar
Significado: A remote sensing technology that measures distances by illuminating a target with laser light and analysing the reflected pulses, creating precise three-dimensional maps of surfaces and objects.
Lidar has revolutionised fields as diverse as archaeology, forestry, autonomous vehicles, and urban planning. Airborne lidar can penetrate forest canopies to reveal hidden archaeological features, while vehicle-mounted systems are central to self-driving car technology. It offers higher spatial resolution than radar and works well in daylight, though it is less effective in heavy rain or fog.
Ejemplos
- Lidar surveys conducted over the Welsh countryside revealed the remains of a previously unknown Iron Age hill fort beneath dense woodland. 在威尔士乡村上空进行的激光雷达调查揭示了茂密林地下方一个此前未知的铁器时代山堡的遗迹。Los estudios con lidar realizados sobre la campiña galesa revelaron los restos de un castro de la Edad del Hierro hasta entonces desconocido bajo una densa arboleda.ウェールズの田園地帯で実施されたライダー調査により、密林の下にこれまで知られていなかった鉄器時代の丘陵要塞の遺跡が発見された。웨일스 전원 지대에서 실시된 라이다 조사를 통해 울창한 삼림 아래에 이전에 알려지지 않았던 철기시대 산성 유적이 발견되었다.
- The autonomous vehicle relied on a roof-mounted lidar unit to build a real-time three-dimensional model of its surroundings. 这辆自动驾驶车辆依靠车顶安装的激光雷达装置实时构建周围环境的三维模型。El vehículo autónomo se apoyaba en una unidad de lidar montada en el techo para construir un modelo tridimensional en tiempo real de su entorno.その自動運転車は屋根に搭載されたライダーユニットを用いて、周囲のリアルタイム三次元モデルを構築していた。그 자율주행차는 지붕에 장착된 라이다 장치를 이용하여 주변 환경의 실시간 3차원 모델을 구축했다.
- Environment Agency lidar data was used to model flood risk across low-lying areas of the Somerset Levels. 环境署的激光雷达数据被用于对萨默塞特平原低洼地区的洪水风险进行建模。Los datos de lidar de la Agencia de Medio Ambiente se utilizaron para modelizar el riesgo de inundación en las zonas bajas de los Somerset Levels.環境庁のライダーデータは、サマセット・レベルズの低地における洪水リスクのモデル化に使用された。환경청의 라이다 데이터는 서머셋 레벨스 저지대의 홍수 위험을 모델링하는 데 사용되었다.

Origen e historia
Originally a portmanteau of 'light' and 'radar,' coined in the 1960s. Some sources treat it as an acronym for 'Light Detection and Ranging,' by analogy with radar.
