Abstract
The attention calling system includes the classification unit for classifying an object into a category based on a traffic scene, the risk calculation unit for calculating the risk value with respect to contact with the object based on the category, and the attention calling unit for outputting the visual display in the horizontally extending belt-like range on the windshield of the moving body. The attention calling unit outputs the visual display in the mode adapted to the risk value of the object.
Claims5
An attention calling system, comprising:
- a light projection device which outputs a visual display on a windshield of a moving body, the visual display being visually recognizable by an operator of the moving body;
- and
- an attention calling device which controls the light projection device to call the operator's attention to objects around the moving body by means of the visual display, wherein:
- the attention calling device includes a detection unit for detecting the objects existing in an area surrounding the moving body, a classification unit for classifying each of the detected objects into one of multiple categories based on at least a type of the object, and a traffic scene in the presence of the detected objects, a risk calculation unit for calculating a risk value indicating a risk degree of contact with the moving body based on the classified category for each of the detected objects, and
- an attention calling unit for outputting the visual display in a predetermined display range on the windshield of the moving body by controlling the light projection device;
- the display range is a horizontally extending belt-like range on the windshield in a width direction of the moving body;
- and
- the attention calling unit displays the visual display indicating each direction position of the detected objects in the display range on the windshield in a mode adapted to display respective calculated risk value with respect to the detected objects.
An attention calling method implemented by a computer, comprising the steps of:
- detecting objects existing in an area surrounding a moving body;
- classifying each of the detected objects into one of multiple categories based on at least a type of the object, and a traffic scene in the presence of the detected object;
- calculating a risk value indicating a risk degree of contact with the moving body based on the classified category for each of the detected objects;
- and
- outputting the visual display in a predetermined display range on the windshield of the moving body by controlling the light projection device disposed in the moving body, wherein:
- the display range is a horizontally extending belt-like range on the windshield in a width direction of the moving body;
- and
- in the step of outputting the visual display, the visual display indicating each direction position of the detected objects is displayed in the display range on the windshield in a mode adapted to display respective calculated risk value with respect to the detected objects.
