In & Out Count By Time

[Adam-Arrayen]

I'm separating out different classes with Yolo
For Example:

    detections_car = detections[detections.class_id == 2]
    detections_truck = detections[detections.class_id == 7]

Then I have 2 lines to count the different classes, works fine, I can output the total with no issue.

Is it possible to write the time in video or perhaps only write it every x minutes for example to calculate the volume between entries?

Example code:

    car_zone_annotator.annotate(annotated_frame, line_counter=car_line_zone)
    truck_zone_annotator.annotate(annotated_frame, line_counter=truck_line_zone)

    # Just counting out 
    carlineoutcounter = car_line_zone.out_count
    trucklineoutcounter = truck_line_zone.out_count
    
    print("Car Count:", carlineoutcounter, "Truck Count:", trucklineoutcounter)

    # Variable to write to the file
    variable_in_wordswrite1 = "Cars Count"
    variable_in_wordswrite2 = "Truck Count"

    # Open a file in write this stuff a to append and write the stream w to just write the final result 
    with open("output.txt", "a") as file:
    # Write the variable to the file
        file.write(f"{variable_in_wordswrite1}: {carlineoutcounter}")
        file.write(f"{variable_in_wordswrite2}: {trucklineoutcounter}")

Produces a stream like below:
(Using print so I can see what's happening but writes to the files a s well.

Car Count: 1 Truck Count: 1
Car Count: 1 Truck Count: 1
Car Count: 1 Truck Count: 2
Car Count: 1 Truck Count: 2
Car Count: 1 Truck Count: 2
Car Count: 2 Truck Count: 2
Car Count: 2 Truck Count: 2
Car Count: 3 Truck Count: 3
Car Count: 3 Truck Count: 3
Car Count: 3 Truck Count: 3
Car Count: 3 Truck Count: 4
Car Count: 3 Truck Count: 4
...... a lot more entries later
Car Count: 87 Truck Count: 23
Car Count: 87 Truck Count: 23
Car Count: 87 Truck Count: 23
