Abstract
To perform an ideal calibration operation, a start switch started manually or by an on-vehicle camera calibration device, a start switching device started by an operation of the start switch and projection devices installed in an outer periphery of a vehicle body, including at least one or more light sources irradiating the surroundings of the vehicle body with light are provided, in which whether a calibration operation is possible or not is determined based on references on a road surface projected by the projection devices.
Claims9
An on-vehicle camera calibration auxiliary device comprising:
- a start switch started manually or by an on-vehicle camera calibration device;
- a start switching device started by an operation of the start switch;
- and
- projection devices installed in an outer periphery of a vehicle body, including at least one or more light sources irradiating the surroundings of the vehicle body with light,
- wherein whether a calibration operation is possible or not is determined based on at least one of unevenness around a vehicle and an inclination of the vehicle, determined from references on a road surface projected by the projection devices.
An on-vehicle camera calibration auxiliary device comprising:
- a start switch started manually or by an on-vehicle camera calibration device;
- a start switching device started by an operation of the start switch;
- a projection device installed in an outer periphery of a vehicle body, including at least one or more light sources irradiating the surroundings of the vehicle body with light;
- a pressure sensor section having plural sensors which detect the weight of the vehicle body;
- a liquid crystal panel section supporting the pressure sensor;
- and
- a pressure point measurement unit measuring a pressure corresponding to a tire position of the vehicle body as a pressurized point by the pressure sensor,
- wherein the projection device projects straight lines for determining a calibration operation around the vehicle so as to correspond to the pressure point measurement unit.
An on-vehicle camera calibration auxiliary device comprising:
- a plurality of projection devices installed in an outer periphery of a vehicle body and comprising at least one or more light sources irradiating surroundings of the vehicle body with light;
- a processor configured to:
- determine at least one of an unevenness of the road surface and an inclination of a vehicle based on references on a road surface projected by the projection devices, and
- determine whether the determined at least one the unevenness of the road surface and the inclination of the vehicle is within an acceptable value;
- and
- a notification device, which, in response to the determining that the determined at least one the unevenness of the road surface and the inclination of the vehicle is within the acceptable value, notifies that the calibration operation is possible and which, in response to the determining that the determined at least one the unevenness of the road surface and the inclination of the vehicle is outside the acceptable value, notifies that the calibration operation cannot be accurately performed.
