Abstract

The present invention relates to an artificial intelligence pedestrian recognition system for vehicle installation for safe right-turn driving, comprising: a camera unit installed on the front and right side of a vehicle to photograph the front and right side of the vehicle to recognize pedestrians and crosswalk identification lines corresponding to the vehicle's forward field of vision or pedestrians and crosswalk identification lines corresponding to the vehicle's right side field of vision; a sound output unit that outputs an alarm sound based on the crosswalk identification lines and pedestrians photographed by the camera unit to indicate right-turn driving of the vehicle; a display unit that outputs real-time video of the crosswalk identification lines and pedestrian information photographed by the camera unit so that the driver inside the vehicle can monitor them; a driver warning display unit installed inside the vehicle that outputs voice or vibration to indicate to the driver when driving risk due to right-turn driving is detected; and an artificial intelligence control unit that analyzes the crosswalk identification lines and pedestrian images photographed by the camera unit to analyze whether the pedestrian is located on the crosswalk identification line, analyzes the pedestrian's voice information, and analyzes the pedestrian's walking direction.

Description

Vehicle-mounted AI pedestrian recognition system for safe right-turn driving The present invention relates to an artificial intelligence pedestrian recognition system for vehicle installation for safe right-turn driving, and more specifically, to an artificial intelligence pedestrian recognition system for vehicle installation for safe right-turn driving that is installed in a vehicle and recognizes pedestrians using artificial intelligence to prevent pedestrian accidents caused by right-turn driving in advance. The current traffic signal system stipulates that vehicles turning right are permitted to pass within a range that does not obstruct pedestrian crossing at the crosswalk located immediately after the turn. However, since drivers often find it difficult to detect pedestrian signals at crosswalks located immediately after a right turn in advance, leading to frequent traffic accidents, various devices and systems are required to prevent traffic accidents caused by right-turning vehicles. As an example of a traffic accident prevention system for such right-turning vehicles, Korean Utility Model Publication No. 20-2016-0003715 (published on October 26, 2016) includes a right-turn signal light indicating the presence of pedestrians on a right-turn crosswalk, which is a crosswalk after turning right at an intersection; a right-turn crosswalk pedestrian confirmation unit confirming whether pedestrians are present in the straight-ahead lane through which vehicles passing after turning right pass within the right-turn crosswalk; a right-turn signal light operating unit that operates the right-turn signal light based on the presence or absence of pedestrians crossing the right-turn crosswalk through the right-turn crosswalk pedestrian confirmation unit; and a right-turn signal light control unit that operates the right-turn signal light only when the pedestrian signal light for the right-turn crosswalk is a pedestrian signal. The right-turn signal light is installed on the sidewalk prior to the right turn at the intersection, and includes a right-turn warning indicator that is displayed when pedestrians are present on the right-turn crosswalk while the pedestrian signal light for the right-turn crosswalk is a pedestrian signal, and an indicator that is displayed when no pedestrians are present on the right-turn crosswalk. A right-turn traffic accident prevention system is disclosed, wherein a pair of right-turn possible indicators are formed, and a right-turn crosswalk pedestrian verification member comprises a camera that photographs the area around the right-turn crosswalk, a detection area setting member that sets the straight lane area through which a vehicle passes after turning right as a detection area among the images of the right-turn crosswalk provided by the camera, and a right-turn crosswalk pedestrian image verification member that analyzes the images captured by the camera to verify whether a pedestrian exists in the detection area of the right-turn crosswalk, and wherein a right-turn traffic light operating member activates the right-turn caution indicator of the right-turn traffic light when it is confirmed that a pedestrian exists in the detection area of the right-turn crosswalk, and activates the right-turn possible indicator of the right-turn traffic light when it is confirmed that no pedestrian exists in the detection area of the right-turn crosswalk. In addition, Korean Patent Publication No. 10-2015-0100214 (published September 2, 2015) discloses a vehicle notification system for pedestrian protection, comprising: a motion detection sensor connected to a driver's signal light or a pedestrian signal light at an intersection to detect the approach and movement of a pedestrian; a transmitting device that receives a pedestrian detection signal transmitted from the motion detection sensor and transmits it to a vehicle approaching the intersection; and a receiving device located at the bottom of the vehicle that receives the pedestrian detection signal transmitted from the transmitting device and transmits it to the vehicle driver, wherein the transmitting device is buried underground in at least two locations along the vehicle's unprotected right-turn or left-turn lane, and the motion detection sensor is linked to the driver's signal light or the pedestrian signal light so that the pedestrian detection cycle operates differently in pedestrian-allowed and pedestrian-unallowed signals. However, in the case of the traffic accident prevention system for right-turning vehicles mentioned above, it is designed to operate based on a relatively complex configuration for detecting pedestrians, and since the installation costs are substantial, there are practical difficulties in applying it to all crosswalks immediately following right turns nationwide. Furthermore, since such systemic technology requires not only equipment costs but also significant installation time, there is a problem in that it take
