TFMini-S是基於TFmini升級的單點測距LiDAR。盲區縮短到10cm,提高了室外性能和不同反射率的精度,可以實現穩定,準確,靈敏和高頻範圍的檢測。
SparkFun 原廠 TFMini-S - Micro LiDAR Module (SEN-16977)
The TFMini-S Micro LiDAR Module is a ToF (Time of Flight) LiDAR sensor capable of measuring the distance to an object as close as 10 centimeters (+/- 6cm up to 6m) and as far as 12 meters (+/-1% starting at 6m)! As with all LiDAR sensors, your effective detection distance will vary depending on lighting conditions and the reflectivity of your target object, but what makes this sensor special is its size. Measuring only 42x15x16mm, the TFMini-S allows you to integrate LiDAR into applications traditionally reserved for smaller sensors.
TFMini-S is a single-point ranging LiDAR based on TFmini upgrade. The blind zone is shortened to 10cm, the outdoor performance and accuracy of different reflectivity are improved, it can achieve stable, accuracy, sensitive and high frequency range detection.
Important: This product does not use laser light for ranging. Instead it contains an LED and optics. Many such systems are being marketed under the name "LiDAR," although it may be more appropriate to think of this device as a "Time-of-Flight Infrared Rangefinder". It differs significantly from traditional IR rangefinders in that it uses ToF to determine range and not triangulation — as is performed by the Sharp GP-series devices.
本產品不使用激光進行測距。 相反,它包含一個LED和光學器件。 許多這樣的系統都以“ LiDAR”的名稱出售,儘管將這種設備視為“飛行時間紅外測距儀”可能更合適。 它與傳統的紅外測距儀有很大不同,因為它使用ToF來確定距離而不是進行三角測量(與Sharp GP系列設備一樣)。
TFmini-SLiDAR是一款基於飛行時間技術(ToF)的單向激光測距儀。它由特殊的光學和電子設備構成,內部集成了面向室內室外各種應用環境的適配算法,雷達身材小巧但測距性能優良。可作為測距工具用來檢測前方障礙物的距離;亦可以作為機器人的眼睛,為機器人的安全避障和路線選擇提供距離信息;在各種機器控制的場景,支持系統的自動化;因為它體積小、重量輕及功耗低的特點,同樣適合用作無人機定高和地形跟隨。
