information
Note: Distance is 2 bytes in cm with the resolution of 1cm. The reflectivity information is the relative reflectivity, which can reflect the
reflectivity performance of the system under the measured environment. The reflectivity information can be used to distinguish the objects of
different materials.
For example, analytic calculating method for channel data of the data packet is: get the hexadecimal number of the distance value in the
packet: 0x72, 0x06. The data is composed of 16 bits and is 16-bit unsigned integer data, represented as: 0x0672. Convert distance value to
decimal numbers: 1650.
The distance value is divided by 100 and the result is 16.50 m. Therefore, the measured distance is 16.50m.
