Abstract
A driving support device according to an embodiment includes an estimation unit, a rendering unit, and an erasing unit. The estimation unit estimates a running state of a movable body based on an image taken on the movable body. The rendering unit produces a prediction line that indicates a predicted direction of travel of the movable body based on the running state estimated by the estimation unit, and superimposes and renders the prediction line on the taken image. The erasing unit erases the prediction line rendered by the rendering unit in a case where the estimation unit estimates that the movable body is stopped.
Claims7
A driving support device, comprising:
- a storage storing therein images sequentially taken on a movable body;
- and
- a processor operatively coupled to the storage, the processor being programmed to:
- acquire an image at a current time taken on the movable body;
- acquire an image taken immediately before the current time from the storage;
- compare the acquired images to detect a difference produced by a change between the image taken at the current time and the image taken immediately before the current time;
- estimate a running state of the movable body based on the difference;
- predict a direction of travel of the movable body based on the difference;
- determine whether the movable body is stopped based on the running state;
- each time a difference between a latest two of the images is detected, produce a prediction line that indicates a trajectory in the predicted direction of travel of the movable body, and superimpose and render the prediction line on the image taken at the current time;
- and
- when the difference between the latest two images is not detected, gradually increase transmittance of a prediction line produced immediately before the movable body is stopped in accordance with passage of time from when the movable body is stopped.
