Abstract

There is provided an object alarm device and an object alarm method, which can surely alarm a driver of a high-risk target object. The object alarm device according to the embodiment includes a detecting unit, a selecting unit and, an alarm information generating unit. The detecting unit detects one or more objects from images captured on a movable body. The selecting unit selects a moving object and a still object from among the objects detected by the detecting unit, in which the still object has a contact possibility with the movable body. The alarm information generating unit generates alarm information on the objects selected by the selecting unit.

Claims

1. An object alarm device comprising:

a processor programmed to;

detect objects from images captured on a movable body;

select one or more moving objects and one or more still objects from among the detected objects, the selected one or more still objects having a contact possibility with the movable body and being located in a moving direction and in a moving range of the movable body; and

generate alarm information on the selected one or more moving objects and the selected one or more still objects,

wherein the processor is programmed to, when the objects are detected at a same distance, select a predetermined number of objects from among the detected objects.

2. The object alarm device according to claim 1, wherein the processor is programmed to generate the alarm information that is obtained by emphasizing a base of a frame that encloses each of the detected one or more objects.

3. The object alarm device according to claim 1, wherein the processor is programmed to generate the alarm information that is obtained by emphasizing a base of a frame that encloses each of the detected objects.

4. The object alarm device according to claim 2, wherein the processor is programmed to generate the alarm information that is obtained by changing a display mode of the base on a basis of a distance between the movable body and each of the detected objects.

5. The object alarm device according to claim 3, wherein the processor is programmed to generate the alarm information that is obtained by changing a display mode of the base on a basis of a distance between the movable body and each of the detected objects.

6. An object alarm method comprising:

detecting objects from images captured on a movable body; and

selecting one or more moving objects and one or more still objects from among the detected objects, the selected one or more still objects having a contact possibility with the movable body and being located in a moving direction and in a moving range of the movable body; and

generating alarm information on the selected one or more moving objects and the selected one or more still objects,

wherein the selecting includes selecting, when the objects are detected at a same distance, a predetermined number of objects from among the detected objects.

7. An object alarm device comprising:

a processor configured to;

detect objects from images captured on a movable body; and

select one or more moving objects and one or more still objects from among the detected objects, the selected one or more still objects having a contact possibility with the movable body,

wherein the processor is further configured to;

when the detected one or more objects are determined to be a still object, determine whether the still object is inside the moving range and in the moving direction of the movable body, and

when the detected one or more objects are determined to be a moving object, determine whether the moving object is in the moving direction of the movable body, and, when the moving object is determined to be in the moving direction of the movable body, generate alarm information irrespective of whether the moving object is inside or outside the moving range, and

wherein the processor is programmed to, when the objects are detected at a same distance, select a predetermined number of objects from among the detected objects.
