  • This product helped me out in a tight deadline and helped an experimental project take flight. However I'm getting a strange latency on the signal readings of about 20 minutes, odd.

    除此之外,表现已经脱离了这个世界。

    我想知道是否有退货政策,因为我们只使用这30天?(送回给您的物流可能很复杂)

  • Now all you need is rotating mirror at an angle that rotates above the sensor, and a position sensor on the mirror and you can have 360 degree range finding with one sensor. At 500hz sample you can almost get 2 samples a second per degree. (though I'd be ok with 1 sample per 1.4 degrees, giving 2 samples a second) Get on it Sparkfun!

  • 在i2c上使用2台激光雷达时出现的问题:更改i2c地址似乎不起作用,是否有人通过读取序列号,然后将序列号和新地址写入正确的寄存器,成功地完成了地址更改?

  • Soooo, the price doubled cuz they were bought by Garmin????

  • 您好,几个月前买了其中一个(本网站,其他丢失的账户)。让它在I2C / Arduino上工作,使用推荐的电容与示例草图(GetDisteance2c),运行一些测试,结果很好,一切都好。昨天开始使用它,同样的设置,首先尝试:10-20结果和沉默,再次尝试,结果,第三次运行 - 没有关于串行的。从那时起,我没有在序列,没有结果,无论是在I2C还是PWM上。在I2C上,我认为它在mylidarlite.begin(0,true)失败。其他人都有这个问题还是解决这个问题?(该设备实际上是新的,电线,电压,Arduino IDE等全部验证和工作顺序)。

  • 你好!

    我对此传感器的可能用例有一个问题:

    I'm trying to measure the distance from this sensor (fixed point) to a moving point with a max movement of 0.5m located 10 meters away.

    是否有一个方法,我可以添加一个标记到我的移动点,以便激光雷达可以测量偏转尽可能好?如果不是的话,我怎么能只测量到那个点的距离呢?

    谢谢,查尔斯

  • Hi, I would like to know if this sensor works on water (Signal will bounce on water?) I need it for a water level tank.

    干杯,

  • 在使用I2C接口使此产品正常工作时遇到一些问题。在PWM模式下工作,所以它至少大部分功能。在I2C模式下,我可以设置并读回R/W寄存器,使通信看起来正常,尽管序列号寄存器返回所有0(可疑)。当我命令进行距离测量时,距离值总是0x2424。测量后,状态寄存器位看起来都正常(无错误情况)。我用一个机器人作为控制器。我可以用一个Arduino来测试它,作为交叉检查,看看它是否是Rio的I2C所特有的。有人有什么想法吗?

  • 也许这将使价格降低到业余爱好者/实验区的更多内容:http://spectrum.ieee.org/cars-that-think/transportation/sensors/osrams-laser-chip-for-lidar-promises-supershort- in-in-in-indoply-packice

  • 有人在RPI + Python I2C SMBus @ 400kbps上尝试过这个吗?似乎完全被我锁定了。我可以获得I2C连接,但是当我触发读取(ACQ_COMMAND 0x04)并读取FULL_DELAY_HIGH / LOW寄存器时,只能提供电源读数。尝试了各种其他方法,包括自由运行模式,没有成功。状态读取始终如一地报告0x26,显示信号和引用溢出。

  • 关于GPS干扰,这是来自附带的产品信息文件:

    "This Limited Warranty also does not apply to, and Garmin is not responsible for, any degradation in the performance of any Garmin navigation product resulting from its use in proximity to any handset or other device that utilizes a terrestrial broadband network operating on frequencies that are close to the frequencies used by any Global Navigation Satellite System (GNSS) such as the Global Positioning Service (GPS). Use of such devices may impair reception of GNSS signals."

  • Does anyone have a set of physical drawings of the housing, or at least some specs on the spacing/size of the mounting holes?

  • 我们使用了早期版本的Lidar-Lite,但由于产生了嘈杂的RFI而停止使用。RFI非常糟糕,导致GPS出现问题。这个问题已经解决了吗?Tnx公司

  • Can we use this for underwater vehicles?

  • 这能用于水下航行器吗?

  • 有人使用v3测量速度吗?v3自由raries are missing some of the v2 components, most noticeably the velocity measurement capability.

  • Hi, I would like to know if the LL3 is still stable and reliable outside. For instance, is it still operating under sunlight, or in an environment disturbed by the rain, the wind or the heat... ? Thank you for your time,

  • Does this work with 3.3V IO or is 5V required? The garmin spec isn't clear, other than to say the i2c can run "up to a maximum of 5V"

  • 没有电容器的人是否能够使用I2C?如果没有,您是否携带电容器是合适的?我真的希望他们摆脱V3上的那个。

    • Currently testing one without the capacitor and it seems to be working fine. I believe the capacitor is suggested to protect the Arduino. Probably a good idea to use one if you can....capacitors are cheaper than Arduino's!

  • 关于v2的偏移量和其他问题是否已经修复,有什么消息吗?它们在Arducopter wiki上有很好的文档记录:http://ardupilot.org/copter/docs/common-rangefinder-lidarlite.html

  • 请重复是什么?

  • 我还想知道V2和V3模型之间进行了哪些更改。这只是一个v2的garmin重新品牌吗?很高兴看到这个产品返回市场。

  • 它很酷,它回来了。您是否知道V2和V3之间的变化是什么?V2上有一些可靠性问题,它们是否固定?

  • 产品页link seems to be wrong, server not found

Lidar Lite V3 ---到目前为止满意

我买了这个在空中无人机上的障碍物检测。它根据PWM模式中的包含指令完全相同。我确实需要添加一个大电容1000 UF(少可能很好),以确保正确地初始化每一个上电。本手册显示了I2C中的电容,但尚不清楚在PWM模式下需要它。

当我把它与PixHawk自动驾驶仪接口时,我发现在触发线上推荐的串联电阻确实起作用了。将触发线直接连接到PixHawk辅助引脚,它似乎运行良好。这周我将带着它进行飞行测试。

简单、快速、准确

我对这个小单位很满意。设置是微风,我用例中的准确性(检测块墙)很好。我真的预计远低于交付的单位,并觉得它值得的价格。我之前使用过许多声纳和IR的单位,发现这个单位更可靠。如果您正在为Arduino挑选它,请确保在电源线上有一个宽大电容,它会在开启时拉过电流的公平位置,推荐680UF盖。

Waste of money - only works in lab - not outside in moisture

I bought three of them for a prototype to be used for a product we want to bring to production. Worked great for a while (all 3 of them) As soon as I got it outside (shooting through rain - but protected from getting wet) it failed miserably. Sunlight killed it. This is for a lab environment. Be careful about hooking it up. Very delicate. I bought a China laser rangefinder for $33. Very happy with it.

很遗憾听到LIDAR的问题。您是否已联系我们的技术支持部门@ TechSupport@sparbetway手机投注kfun.com,并提供有关您使用的传感器的环境的信息?必威娱乐登录平台他们可以帮助提供一些建议和解决方案,以帮助您描述的问题。

Meets specs, used in a different application.

我购买了它以检测高达90英尺的距离的反射杆。距离每个极的距离被预先确定以避免周围物品。结果用于三角形位置和标题,用于AGV导航外部。它能够在50英尺下使用默认设置清楚地检测四分之一英寸宽反射条带。修改设置应提供一旦安装在旋转基座上,可以提供非常坚固且可靠的检测方法。

这是我的第三个

Mainly because it's small enough to mount on a mid-sized multi-rotor, I know the wiring and I sold #2, so needed another one.

I use them solely for distance measuring, as a radar altimeter and object ranging, having them mounted on servos that follow the camera's gimbal tilt. I use them PWM, connected to a Pitlabs OSD board, which then displays the distance in the video stream.

对我来说,该设备适用于广告,可靠地显示1-150英尺的距离。PWM信号需要470欧姆电阻以连续触发它。

在蹩脚的新闻部门,这非常令人沮丧地支付50%,而不是前两个花式贴纸。

伟大的小激光雷达收发机

我设计和工作的科学激光雷达为科罗拉多大学,我印象深刻的设备。通常情况下,具有这种距离分辨率的飞行时间激光雷达由于其惊人的光速和捕获所需的高速而很困难。这个设备使用了一个巧妙的技巧来解决这个问题,在一个小的低功耗和易于使用的封装中,它在厘米级的分辨率上做得非常好。我用Arduino在几分钟内就有了一个可操作的装置。

Doesn't work through glass

我正在考虑使用这款全尺寸汽车仪表板安装设备。我创建了一个测试钻机,带有WiFi适配器的小猎犬骨黑色,将措施发送到移动设备(手机或平板电脑)。如果我在外面走在外面并指向各种对象的设备,一切都适用于此设置。但是,当我尝试将其安装在仪表板上时,窗口将其读取0的窗口更改为0。

I'm not surprised by a limitation like this, but it is annoying.

总之,当使用此设备时,请确保设备的正面是敞开的。前面没有玻璃或塑料。

尚未审查,零件不包括在内

我必须等待审查这个单位,因为150美元的价格不包括所需的电解电容和电阻。一旦他们到达并使用安装外部离散元件,我就可以审查。到目前为止,不高兴。更新以后。

我还没有收到你这批货。它在哪里?

According to the tracking number, it was delivered on 1/04/17 at 12:45. Hopefully you've gotten it by now, and will have a chance to work with it soon. Once you do, please let us know what you think!

对漫反射目标的强大能力

作品良好,Arduino图书馆是基本的,但工作。我希望用逆向反射目标使用它,但它们倾向于过载接收器,并且您会得到含糊不清的结果。我会继续尝试。

非常令人兴奋的传感器。

I have high hopes for the Lidar sensor to sense distance and direction on a outdoor robot. In this installation, the Lidar sits on a 180 rotation servo to provide the angle to the object detected. The outdoor tests have been more successful than with other sensors tried for this purpose. It is being used in the PWM mode now because the Arduino mega serial ports are busy. Yeah, I know. So far, so good.

Cool and Capable Sensor

Range and refresh rate set this sensor apart from other range detectors such as the Maxbotix outdoor sensors which are comparably priced. Not only can the LIDAR resolve objects farther, it is able to "see" soft and non-reflective objects such as people. Also, it can refresh hundreds of times a second as opposed to a 6Hz refresh on the outdoor Maxbotix's gear.

一个投诉,数据流中有一个公平的噪声 - 特别是当它没有得到任何/强烈的回报时。您需要过滤,这将降低有效的刷新率。

Great little sensor...

。。。but the mounting hole dimensions aren't even given on the spec sheet. They ALMOST line up with the Actobotics "1.5 inch" hole pattern - see //www.psybik.com/products/12103 - that would be a plus!

Going to be using it to detect objects in front of my boat - so it'll be on a pan and tilt assembly which keeps it level using the Razor 9dof IMU M0 - //www.psybik.com/products/14001 as the sensor and controller.

多开心!

Amazing Piece of Technology!

惊人的设备!非常准确,但我建议平均数据点。而且,在小于30厘米时也不准确。

really nice little unit

A thorough read of the Garmin data sheet and a look at the library examples got me going. The unit operates exactly as specified and now it's being integrated into the rest of the robot systems. It works great so far in measuring interior spaces, walls, etc., Tests this summer will examine how well it does outside and on people avoidance. But solid product.

Fantastic!

Disappointed, really!

尝试使用其他3个距离传感器后,我discovered at a high cost the lack of detailed descriptions in the datasheets and the websites themselves. For my project that needs a laser beam in visible and RED light, it is disappointing to buy a product that does not report in such a way as to highlight that the light beam is IR, ie infra red. This feature makes it impossible to use this sensor in my project. Another thing I found in this sensor was that it did NOT report the distances up to 300 cm, which contradicts the information in the datasheet that indicates 40 m. Could it be that in my expectation of having the problem resolved, I did not see such information or did the information on the site and datasheet really need reformulation?
