Abstract
The image processing device includes a scale correction unit. In a case where a difference between a width of a lane calculated by a lane-width calculation unit and a width of the lane acquired from map data is greater than a predetermined value that serves as a criterion for correcting errors, the scale correction unit corrects a correlation between a length of a subject in a captured image and the number of pixels constituting the captured image.
Claims5
An image processing device comprising:
- a storage unit configured to store executable instructions;
- and
- an electronic control unit (ECU) communicatively coupled to the storage unit, the ECU configured to execute the executable instructions to:
- calculate a width of a lane in which a vehicle travels from a captured image, in which a front of the vehicle in a traveling direction is captured, based on a correlation between a length of a subject in the captured image and a number of pixels constituting the captured image;
- acquire information indicating a position of the vehicle;
- acquire information indicating a width of the lane in which the vehicle travels, from map data, based on the information indicating the position of the vehicle;
- and
- correct the correlation between the length of the subject in the captured image and the number of pixels constituting the captured image in a case where a difference between the width of the lane calculated from thee captured image and the width of the lane acquired from the map data is greater than a predetermined value that serves as a criterion for correcting errors.
