把对比的信息生成CSV格式文件，并添加水平精度、高程精度、法相精度和速度精度

为了将对比信息生成CSV格式文件，您可以使用Python的csv模块。下面是一个示例代码，可以将多个NMEA文件和一个NMEA文件的水平精度、高程精度、法相精度和速度精度写入CSV文件：

import csv

# Define a function to write comparison results to a CSV file
def write_comparison_results_to_csv(file_list, results_file):
    # Write header row to CSV file
    header = ['NMEA File', 'Horizontal Accuracy (m)', 'Vertical Accuracy (m)', 'Course Accuracy (degrees)', 'Speed Accuracy (m/s)']
    with open(results_file, 'w', newline='') as f:
        writer = csv.writer(f)
        writer.writerow(header)

        # Loop through list of NMEA files and calculate accuracy for each
        for nmea_file in file_list:
            # Calculate accuracy for current NMEA file
            horizontal_accuracy, vertical_accuracy, course_accuracy, speed_accuracy = calculate_accuracy(nmea_file)

            # Write accuracy results to CSV file
            row = [nmea_file, horizontal_accuracy, vertical_accuracy, course_accuracy, speed_accuracy]
            writer.writerow(row)

您可以使用上面的函数将多个NMEA文件和一个NMEA文件的水平精度、高程精度、法相精度和速度精度写入CSV文件。例如：

file_list = ['nmea_file1.txt', 'nmea_file2.txt', 'nmea_file3.txt', 'nmea_file4.txt']
results_file = 'accuracy_results.csv'

write_comparison_results_to_csv(file_list, results_file)

这将在当前工作目录中创建一个名为“accuracy_results.csv”的文件，并将水平精度、高程精度、法相精度和速度精度写入该文件。
