Installation error display control apparatus and installation error detection apparatus of onboard camera
An installation error detection apparatus of an onboard camera includes: an input portion that receives a photographed image; a storage portion that stores position information of a feature point of the vehicle; a feature point detection portion; a determination portion that determines whether the installation position of the onboard camera is the proper position; and a notification portion that informs installation defect of the onboard camera. The notification portion calculates the installation position of the onboard camera required to minimize the deviation amount and corrects the photographed image by the onboard camera. The notification portion detects the feature point and calculates a similarity degree of the position of the feature point and the position information. The notification portion determines the installation defect of the onboard camera and informs the installation defect. The notification portion determines that a vehicle body is deformed and informs the vehicle body being deformed.
1. An installation error detection apparatus of an onboard camera, the installation error detection apparatus receiving a photographed image by the onboard camera installed to a vehicle so as to photograph a periphery of the vehicle and being used to determine whether an installation position of the onboard camera is a proper position, the installation error detection apparatus comprising:
an input portion that receives the photographed image;
a storage portion that stores position information of a feature point of the vehicle appearing in the photographed image when the onboard camera is installed to the proper position;
a feature point detection portion that detects the feature point of the vehicle out of the photographed image received from the input portion;
a determination portion that determines whether the installation position of the onboard camera is the proper position based on a position of the feature point in the photographed image detected by the feature point detection portion and the position information stored in the storage portion; and
a notification portion that, when the determination portion determines that the installation position of the onboard camera is improper, informs installation defect of the onboard camera,
wherein:
the notification portion calculates the installation position of the onboard camera required to minimize the deviation amount based on the deviation amount between position information of the feature point detected by the feature point detection portion and the position information stored in the storage portion and corrects the photographed image by the onboard camera based on a calculated installation position of the onboard camera, when the determination portion determines that the installation position of the onboard camera is improper;
the notification portion detects the feature point of the vehicle out of the photographed image after correction and calculates a similarity degree of the position of the feature point and the position information stored in the storage portion;
the notification portion determines the installation defect of the onboard camera and informs the installation defect in a case where the similarity degree is less than a threshold value set in advance; and
the notification portion determines that a vehicle body is deformed and informs the vehicle body being deformed in a case where the similarity degree is more than or equal to the threshold value.
