VL53L0x环境光灵敏度无法测量距离

问答对人有帮助，内容完整，我也想知道答案 0 你好我正在测试VL53L0X飞行时间传感器，以便了解它对环境光的抵抗力，结果证明，如果你将一个具有高红外线含量的光源（如卤素灯泡）指向传感器它无法测量距离。即使照度很低。它简单地说'没有目标'。角度相对于光轴越陡，问题就越严重。有谁有这个问题，并找到了解决方案？最好的问候索伦＃light-intensity #light＃vl53l0x＃vl53l0 #tof #ir #time-of-flight＃ambient-light #halogen 以上来自于谷歌翻译以下为原文 Hi I am testing the VL53L0X time-of-flight sensor, in order to find out how resistant it is to ambient light and it turns out that if you point a light source with a high IR content (like a halogen light bulb) towards the sensor it cannot measure the distance. Even if the illuminance is very low. It simply says 'No Target'. The problem gets worse the steeper the angle is with respect to the optical axis. Has anyone had this problem and found a solution?Best regardsSoren #light-intensity #light #vl53l0x #vl53l0 #tof #ir #time-of-flight #ambient-light #halogen 0

答案对人有帮助，有参考价值 0 传感器发出的光线为940nm，刚好超出您的能量。由于要求它完全是眼睛安全的，因此光线相对暗淡。当面对太多环境光时，缺乏强度会使其陷入困境。这有点像在光天化日之下闪亮的笔灯手电筒。不幸的是，卤素灯有大量的940nm，这是你的问题。通常，干涉限制了传感器可以测距的距离。传感器在室内可以达到2M，但在明亮的阳光下可以达到50cm。显然直视940nm光源会使传感器完全失明。因此，需要在您的环境中进行测试。 - 约翰以上来自于谷歌翻译以下为原文 The sensor emits light at 940nm which is just above what you can see. The light is relatively dim, due the requirement that it be completely eye safe. The lack of intensity does get it into trouble when faced with too much ambient light. It's sort of like shinning a pen-light flashlight in broad daylight. Unfortunately Halogen lights have a huge amount of 940nm, which is your problem. Normally the interference limits the distance which the senor can range. The sensor does well up to 2M indoors, but is limited to 50cm in bright sunlight. Clearly looking directly into a 940nm light source would completely blind the sensor. So testing in your environment is required. - john
