1. A system for detecting a pedestrian at a crosswalk and preventing an accident on basis of artificial intelligence, the system comprising:
a camera device installed on a mast arm, which is installed at a top of a traffic light pole installed at the crosswalk, to capture the pedestrian and a periphery of the crosswalk;
a pedestrian detection module for detecting the pedestrian in an image captured by the camera device through a pre-installed image analysis solution;
a color detection module for detecting a current blinking color of a traffic light including a pedestrian traffic light and a driving traffic light;
a warning signal output module for outputting a jaywalking warning message to the pedestrian waiting at the crosswalk according to a detection result of the color detection module and a detection result of the pedestrian detection module,
a safety induction block module installed on a bottom surface of the crosswalk so as to be controlled in conjunction with the traffic light to perform blinking;
a communication module for transmitting, when the detection result of the color detection module and the detection result of the pedestrian detection module are determined as jaywalking or an abnormal behavior of the pedestrian, a determination result to an outside;
a database for storing the detection result of the color detection module, the detection result of the pedestrian detection module, and determination result information on the jaywalking or the abnormal behavior analyzed by the warning signal output module; and
a control module for controlling operations of the camera device, the pedestrian detection module, the color detection module, the warning signal output module, the safety induction block module, the communication module, and the database, wherein:
the warning signal output module detects the current blinking color of the traffic light based on blinking information of the safety induction block module, which is obtained from the camera device.
