     The application of sound loop motor driven Lidar sensor in unmanned driving. The industry generally believes that the development trend of automotive technology is unmanned. Therefore, Internet companies and automotive companies around the world have invested in the development and research of this subversive technology and have achieved some achievements. Take China.  Geely announced that it will use unmanned vehicles in designated areas during the 2022 Asian Games; After Baidu announced that it will soon launch a new generation of unmanned bus Abolong.
When it comes to unmanned and closely related Lidar sensors, the underside of unmanned support can be divided into three parts, namely sensors, high-precision maps, and computing platforms, according to the audio coil motor editor. In terms of sensors, mainstream sensors are divided into millimeter-wave radar, Lidar and camera.
     Sound coil motor small editor first to share the advantages and disadvantages of the next three sensors: camera prices are moderate, mature technology, can identify pedestrians, vehicles, road signs and other objects, but vulnerable to visual, night dark light, rain and snow weather and other factors. The laser radar has wide detection angles and high accuracy. The laser radar with high precision in cm can achieve high precision self-positioning and object identification and tracking, and positioning can be accurate to specific lanes. Millimeter wave radar can be measured far away and can work steadily in various harsh environments such as rain and snow, but the accuracy is not high. Based on this, unmanned sensors used for control are either cameras or lidar.
     According to the audio coil motor editor, the Lidar emits a laser beam and then receives a beam of light reflected from a distant object to obtain distance information from a distant object by measuring the flight time of the beam. However, the laser beams are very narrow and they do not scatter, so a single laser radar pulse can only perceive a very small object. For practical applications, Lidar sensors have to be "scanned" in some form. Most Lidar sensors connect to a motor that rotates them. Once the laser emission synchronizes with the motor's motion, we can know where the laser is pointing and synthesize the overall imaging of the front environment. Therefore, the field of view of the Lidar depends on the angle of rotation of the motor. At present, there have been cases in which the motor adopts a coil motor.
