This Program uses the OpenCV library (cv2
) to capture video from a camera and display it as ASCII art in the console. Here's a breakdown of the key components:
-
Imports: The code imports the
cv2
library for computer vision and theos
library for operating system-related functions. -
Settings: The
SHOW_REAL_VIDEO
variable is a boolean flag that, when set toTrue
, displays the real camera video in a side panel. When set toFalse
, only the ASCII art representation is displayed in the console. -
Function Definitions:
convert_row_to_ascii(row)
: Converts a row of grayscale pixel values to ASCII characters.convert_to_ascii(input_grays)
: Converts a 2D array of grayscale pixel values to ASCII characters using theconvert_row_to_ascii
function.print_array(input_ascii_array)
: Clears the console and prints the ASCII representation of a 2D array of ASCII characters.
-
Main Loop:
- Initializes a video capture object (
cap
) usingcv2.VideoCapture(0)
to capture video from the default camera (index0
). - Enters a
while
loop that continues until the user presses the 'q' key. - Gets the screen size for reducing the video resolution.
- Reads a frame from the camera (
cap.read()
) and converts it to grayscale usingcv2.cvtColor
. - Resizes the grayscale frame to match the screen resolution using
cv2.resize
. - Converts the resized frame to ASCII art using
convert_to_ascii
and prints it usingprint_array
. - Optionally, displays the real video frame if
SHOW_REAL_VIDEO
isTrue
. - Releases the video capture object (
cap.release()
) and closes all OpenCV windows (cv2.destroyAllWindows()
) when the program is terminated.
- Initializes a video capture object (
Overall, the program continuously captures video from the camera, converts it to ASCII art, and displays it in the console or in a side panel, depending on the SHOW_REAL_VIDEO
setting.
