■ Detection range of the cameras and sensors
●If a parked vehicle is behind the target parking space and the distance between it and the vehicle
becomes far , it may no longer be able to be detected . Depending on shape or condition of a parked
vehicle , the detection range may become short or the vehicle may not be detected .
● Objects other than parked vehicles , such as columns , walls , etc .,
may not be detected . Also , if they are detected , they may cause the target parking space to be misaligned .
■ Situations in which white parking space lines may not be recognized properly
●In situations such as the following , parking space lines on the road
surface may not be detected :
• When the parking space does not use white lines ( parking space
boundaries are marked with rope , blocks , etc .)
• When the parking space lines are
faded or dirty , making them unclear
• When the road surface is bright ,
such as concrete , and the contrast between it and the white parking space lines is small
• When the parking space lines are any color other than yellow or white
• When the area surrounding the parking space is dark , such as at night , in an underground parking lot , parking garage , etc .
• When it is raining or has rained and the road surface is wet and reflective or there are puddles
