I cannot read the ''.csv'' files generated by the livox_controller_demo.py through any tools

[lyy-1997-hub]

1. when I used: import pandas as pd pc_data = pd.read_csv("livoxpoints.csv", header=None, sep='\t', error_bad_lines=False) print(pc_data) But only got: pandas.errors.ParserError: Error tokenizing data. C error: Buffer overflow caught - possible malformed input file.
2. when I used: filename = 'livoxpoints.csv' with open(filename, encoding="UTF-8") as f: reader = csv.reader(f) header_row = next(reader) print(header_row) first_row = next(reader) print(first_row) But only got: UnicodeDecodeError: 'utf-8' codec can't decode byte 0xcd in position 19: invalid continuation byte
3. And I used the CloudCompare to open the 'livoxpoints.csv': I can only get 7 columns of unrecognized Mistaken Code So, I don't know what's wrong :（ . Could you help me?Please

By the way, I used the Horizon. Maybe besides the IP address, are there any other parameters that need to be changed?

And I changed my computer IP address to 192.168.1.50, then used automatic connection "connected = sensor.auto_connect("192.168.1.50")". It can connect successfully, but the file which I got cannot be opened: (

These are all the information when I run the livox_controller_demo.py :

I think your data is in binary form, u need to convert it into csv. in this line: 192.168.1.131 --> closed BINARY file: livoxpoints.csv , You data is being written in a file with name " livoxpoints.csv". Here .csv is not the extension, its part of the file name, extension can be .bin in your case.

if u see in livox_controller_demo.py file you will find that there is a function call at line number 177 which is opl.convertBin2LAS(filePathAndName, deleteBin=True) Use this to convert your bin file into CSV and then use it in cloudcompare or anywhere else.
