Abstract
A driving information display apparatus and method corrects camera pose values using a vanishing point. The apparatus includes a processor configured to receive driving guidance and vehicle location information, control the output of a guidance screen, and set a crop area in an image from a forward-view camera based on the calculated vanishing point. The storage unit stores road information, algorithms, and camera pose values, allowing the processor to generate a guidance screen by integrating the driving guidance information within the crop area centered on the vanishing point.
Claims18
A driving information display apparatus comprising:
- a processor configured to receive driving guidance information and vehicle location information and perform control to output a guidance screen corresponding to the driving guidance information;
- and
- a storage unit including at least one memory configured to store road information and algorithms executed by the processor;
- wherein the storage unit is further configured to store camera pose values of a forward-view camera of a vehicle;
- and
- wherein the processor is further configured to:
- determine whether the camera pose values can be corrected based on a driving route and driving speed information of the vehicle,
- in response to determining that the camera pose values can be corrected, correct the camera pose values using an image captured from the forward-view camera of the vehicle, and store the corrected camera pose values in the storage unit,
- set, in the image from the forward-view camera of the vehicle, a crop area so that a location of a vanishing point calculated based on the camera pose values is a center of the crop area, and
- generate the guidance screen by adding the driving guidance information to the crop area.
A driving information display method, the driving information display method being performed by a driving information management server equipped with a processor and a storage unit including at least one memory, the driving information display method comprising:
- a pose value storage step of storing camera pose values of a forward-view camera of a vehicle in the storage unit, using the processor;
- a pose value correction step of determining whether the camera pose values can be corrected based on a driving route and driving speed information of the vehicle using the processor, and in response to determining that the camera pose values can be corrected, correcting the camera pose values by the processor, using an image from the forward-view camera of the vehicle, and storing the corrected camera pose values in the storage unit;
- a crop area setting step of setting, in the image from the forward-view camera of the vehicle, a crop area so that a location of a vanishing point calculated by the processor based on the camera pose values is a center of the crop area;
- and
- a guidance screen output step of generating a guidance screen, using the processor, by adding driving guidance information to the crop area, and outputting the guidance screen.
