Description

NOTE: It is recommended to use the upgraded version,  RPLiDAR A2M8 360 Degree Laser Scanner Kit - 12M Range as your alternative choice (unit price $319).


The RPLIDAR A2 is the next generation low cost 360 degree 2D laser scanner (LIDAR) solution developed by SLAMTEC. It can take up to 4000 samples of laser ranging per second with high rotation speed. And equipped with SLAMTEC patented OPTMAG technology, it breakouts the life limitation of traditional LIDAR system so as to work stably for a long time.


The system can perform 2D 360-degree scan within a 6-meter range. The generated 2D point cloud data can be used in mapping, localization and object/environment modeling.


The typical scanning frequency of the RPLIDAR A2 is 10hz (600rpm). Under this condition, the resolution will be 0.9°. And the actual scanning frequency can be freely adjusted within the 5-15hz range according to the requirements of users.


The RPLIDAR A2 adopts the low cost laser triangulation measurement system developed by SLAMTEC, which makes the RPLIDAR A2 has excellent performance in all kinds of indoor environment and outdoor environment without direct sunlight exposure. Meanwhile, before leaving the factory, every RPLIDAR A2 has passed the strict testing to ensure the laser output power meet the standards of FDA Class I.


System connection

The RPLIDAR A2 consists of a range scanner core and the mechanical powering part which makes the core rotate at a high speed. When it functions normally, the scanner will rotate and scan clockwise. And users can get the range scan data via the communication interface of the RPLIDAR and control the start, stop and rotating speed of the rotate motor via PWM.

RPLIDAR System Composition


Introduction


The RPLIDAR A2 comes with a rotation speed detection and adaptive system. The system will adjust the angular resolution automatically according to the actual rotating speed. And there is no need to provide complicated power system for RPLIDAR. In this way, the simple power supply schema saves the BOM cost. If the actual speed of the RPLIDAR is required, the host system can get the related data via communication interface.


The detailed specification about power and communication interface can be found in the following sections.


Mechanism


The RPLIDAR A2 is based on laser triangulation ranging principle and adopts the high-speed vision acquisition and processing hardware developed by SLAMTEC.


The system ranges more than 4000 times per second.

The RPLIDAR Working Schematic


During every ranging process, the RPLIDAR emits modulated infrared laser signal and the laser signal is then reflected by the object to be detected. The returning signal is then sampled by vision acquisition system in RPLIDAR and the DSP embedded in RPLIDAR starts processing the sample data and outputs distance value and angle value between object and RPLIDAR via communication interface.

When drove by the motor system, the range scanner core will rotate clockwise and perform the 360-degree scan for the current environment.


Safety and Scope


The RPLIDAR A2 system uses a low power infrared laser as its light source, and drives it by usting modulated pulse. The laser emits light in a very short time frame which can ensure its safety to human and pet, and it reaches Class I laser safety standard.

The modulated laser can effectively avoid the interference from ambient light and sunlight during ranging scanning process, which makes RPLIDAR work excellent in all kinds of indoor environment and outdoor environment without sunlight.

描述

RPLIDAR A2是SLAMTEC開發的新一代低成本360度2D激光掃描儀(LIDAR)解決方案。它可以每秒鐘高達4000個激光測距樣品,高轉速。並配備SLAMTEC專利OPTMAG技術,突破了傳統LIDAR系統的使用壽命限制,長期穩定工作。

 

該系統可以在6米範圍內進行二維360度掃描。生成的二維點雲數據可用於繪圖,定位和對象/環境建模。

 

RPLIDAR A2的典型掃描頻率是10hz(600rpm)。在這種情況下,分辨率將是0.9°。實際的掃描頻率可以根據用戶的要求在5-15hz的範圍內自由調節。

 

RPLIDAR A2採用SLAMTEC開發的低成本激光三角測量系統,使得RPLIDAR A2在各種室內環境和室外環境下都有優異的性能,無日照直射。同時,在出廠前,每台RPLIDAR A2都通過了嚴格的檢測,確保激光輸出功率符合FDA一級標準。

 

系統連接

RPLIDAR A2由一個範圍掃描儀核心和使核心高速旋轉的機械供電部分組成。當功能正常時,掃描儀將旋轉並順時針掃描。用戶可以通過RPLIDAR通訊接口獲取距離掃描數據,通過PWM控制旋轉電機的啟動,停止和轉速。

介紹

 

RPLIDAR A2配備了轉速檢測和自適應系統。系統會根據實際轉速自動調整角度分辨率。而且不需要為RPLIDAR提供複雜的電源系統。這樣,簡單的供電方案節省了BOM成本。如果需要RPLIDAR的實際速度,主機系統可以通過通訊接口獲取相關數據。

 

有關電源和通信接口的詳細說明可以在下面的章節中找到。

 

機制

RPLIDAR工作示意圖

 

在每個測距過程中,RPLIDAR發出調製後的紅外激光信號,激光信號被待檢測物體反射。通過RPLIDAR中的視覺採集系統採集返回信號,嵌入在RPLIDAR中的DSP開始處理採樣數據,通過通信接口輸出物體與RPLIDAR之間的距離值和角度值。

當電機系統驅動時,掃描範圍核心將順時針旋轉,並對當前環境進行360度掃描。

 

安全和範圍

 

RPLIDAR A2系統採用低功率紅外激光器作為光源,並通過調製脈衝驅動。激光在很短的時間內發光,保證人體和寵物的安全,達到I類激光安全標準。

調製後的激光在測距掃描過程中可以有效的避免周圍光線和陽光的干擾,使得RPLIDAR在各種室內環境和室外環境下均無日光照射效果出色。
