Influencing Factors Of Selecting And Purchasing Lidar

2019-08-14
LiDAR, as the standard of positioning and navigation for robots, plays an important role in helping robots to walk independently. As a sensor mainly used for laser ranging, the data of measuring distance, scanning frequency, angular resolution and measuring accuracy must be an important index for most people to measure, but in addition, there are many other indicators. Two very important but seldom noticed indicators are also important factors to consider when choosing products.

1. Detection rate of dark objects

In the actual working scene, there are many dark objects besides the white wall, such as furniture, dark wallpaper, etc. At this time, whether the Laser Ranging Sensor (lidar) can detect the dark objects smoothly is particularly important, otherwise it is easy to cause problems in robot positioning and mapping, and for the later robot work. Important impact.

2. Anti-interference ability of ambient light

In addition to the detection ability of dark objects, the robot will be affected by various environmental illumination in the actual environment. The sunlight projected from the outside of the window, the artificial light source in the room and even the direct exposure to the outdoor work may interfere with the lidar.
