System for warning about intersection danger based on situation prediction
Provided is a system for warning about intersection danger on the basis of behavior prediction. The system includes a sensor for detecting and predicting actions of surrounding objects, such as vehicles and pedestrians, and a function of providing an alarm feedback and can perform independent computation due to a separate processor installed therein for edge computing.
1. A system for warning about an intersection danger on a basis of behavior prediction, the system comprising:
a first box configured to detect a vehicle and output a warning to a driver of the vehicle; and
a second box configured to detect a pedestrian and output a warning to the pedestrian,
wherein the system is disposed on a sidewalk to simultaneously acquire an image of the vehicle and an image of the pedestrian;
a pedestrian image receiver;
a pedestrian action predictor configured to predict an action of the pedestrian after a certain time has elapsed on a basis of image data received in the pedestrian image receiver;
a vehicle image receiver;
a vehicle movement predictor configured to predict movement of the vehicle after the certain time has elapsed on a basis of image data received in the vehicle image receiver;
a danger prediction determiner configured to determine whether a dangerous situation will occur on a basis of data of the pedestrian action predictor and data of the vehicle movement predictor; and
a warning displayer,
wherein the first box and the second box have the same appearance and are installed symmetrically with respect to a post,
a first image sensor configured to acquire the image of the vehicle is installed on an external surface of the first box,
a second image sensor configured to acquire the image of the pedestrian is installed on an external surface of the second box,
the second image sensor images eyes in the pedestrian's face and the pedestrian's gaze and transmits an eye image and a gaze image to the pedestrian action predictor,
the pedestrian action predictor calculates a posture after the certain time has elapsed on a basis of the pedestrian's gaze, and
the system including the first box and the second box is installed at an intersection in which the vehicle makes a right turn and a crosswalk is disposed immediately after where the vehicle makes the right turn.
2. The system of claim 1 , wherein the danger prediction determiner determines that the dangerous situation will occur on the basis of the data of the pedestrian action predictor and the data of the vehicle movement predictor when locations of the pedestrian and the vehicle overlap or are within a certain distance after the certain time has elapsed.
3. The system of claim 1 , wherein a beam projector configured to notify the vehicle driver of the dangerous situation is installed on the external surface of the first box and displays text or an image providing a notification of the dangerous situation at a certain distance in front of the crosswalk, and
another beam projector configured to notify the pedestrian of the dangerous situation is installed on the external surface of the second box and displays text or an image providing a notification of the dangerous situation at the sidewalk in front of the crosswalk.
4. The system of claim 1 , wherein an electronic board configured to notify the vehicle driver of the dangerous situation is installed on the external surface of the first box, and
another electronic board configured to notify the pedestrian of the dangerous situation is installed on the external surface of the second box.
