Abstract

Provided are equipment operation safety monitoring system and method and computer-readable medium having a program recorded thereon, the program allowing a computer to execute the method. The equipment operation safety monitoring system includes an image input unit, an integrated image generation unit, a guideline generation unit, and an image output unit. The image input unit is mounted on heavy equipment and inputs a plurality of images acquired by photographing partitioned areas in all the directions around the heavy equipment. The integrated image generation unit generates an integrated image including the areas in all the directions around the heavy equipment by using the plurality of the images. The guideline generation unit generates a guideline indicating a position separated by a predetermined distance from the heavy equipment. The image output unit illustrates the guideline on the integrated image and outputs the integrated image.

Claims

1. An equipment operation safety monitoring system comprising:

an image input unit which is mounted on heavy equipment and which inputs a plurality of images acquired by photographing partitioned areas in all the directions around the heavy equipment;

an integrated image generation unit which generates an integrated image including the areas in all the directions around the heavy equipment by using the plurality of the images;

a guideline generation unit which generates a guideline indicating a position separated by a predetermined distance from the heavy equipment; and

an image output unit which illustrates the guideline on the integrated image and outputs the integrated image.

2. The equipment operation safety monitoring system according to claim 1, wherein the integrated image generation unit generates the integrated image by correcting the input images according to a characteristic of the image input unit.

3. The equipment operation safety monitoring system according to claim 1, further comprising an approaching object determination unit which determines whether or not there is an object approaching the heavy equipment by comparing the images input by the image input unit with previously input images.

4. The equipment operation safety monitoring system according to claim 3, further comprising a warning signal output unit which outputs a warning signal in the case where the approaching object determined by the approaching object determination unit is within a predetermined distance from the heavy equipment.

5. The equipment operation safety monitoring system according to claim 2, wherein the integrated image generation unit generates the integrated image in a top view format as seen from the top of the heavy equipment.

6. The equipment operation safety monitoring system according to claim 1, wherein the guideline generation unit generates the guideline based on an installation height and angle of the image input unit.

7. An equipment operation safety monitoring method comprising:

an image input step of inputting a plurality of images acquired by photographing partitioned areas in all the directions around heavy equipment in an equipment operation safety monitoring system mounted on the heavy equipment;

an integrated image generation step of generating an integrated image including the areas in all the directions around the heavy equipment by using the plurality of the images;

a guideline generation step of generating a guideline indicating a position separated by a predetermined distance from the heavy equipment; and
