Article delivery system
View Patent ↗When monitoring a logistics line and outputting a video image on a display, a privacy-protected video image processor uses an image of a first specific region corresponding to an area of the logistics line as it is among an original image captured by a capture, and performs mask processing on a person detected in an image of a region other than the first specific region.
1. An article delivery system, comprising:
a camera positioned adjacent to a conveyor and configured to capture an image of the conveyor and an area surrounding the conveyor, wherein the conveyor is configured to move articles placed thereon;
at least one display; and
a processor coupled to the camera and the display, wherein the processor, in operation:
extracts a first image of the conveyor out of the image captured by the camera;
in a second image other than the first image out of the image, detects a person included in the second image and applies mask processing to the person in the second image;
extracts a third image of a location at which a person is continuously present out of the second image and applies mask processing to the location; and
outputs a composite image of the first image, the second image minus the third image, and the third image to the display, where the first image shows the conveyor, the second image minus the third image shows the area surrounding the conveyor in which the person is masked, and in the third image the location at which a person is continuously present is masked.
2. The article delivery system of claim 1 further comprising:
a storage device that stores the image output from the camera.
3. A method of monitoring an article delivery system which includes a camera, at least one display, and a processor coupled to the camera and the display, the method comprising:
positioning the camera
adjacent to a conveyor configured to move articles thereon;
operating the camera to capture an image of the conveyor and an area surrounding the conveyor and forwarding the image to the processor;
extracting, in the processor, a first image of the conveyor out of the image captured by the camera;
in a second image other than the first image out of the image, detecting a person included in the second image and applying mask processing to the person in the second image;
extracting a third image of a location at which a person is continuously present out of the second image and applying mask processing to the location; and
outputting a composite image of the first image, the second image minus the third image, and the third image from the processor to the display, where the first image shows the conveyor, the second image minus the third image shows the area surrounding the conveyor in which the person is masked, and in the third image the location at which a person is continuously present is masked.
4. A camera device used in an article delivery system, the camera device comprising:
a camera positioned adjacent to a conveyor and configured to capture an image of the conveyor and an area surrounding the conveyor, wherein the conveyor is configured to move articles placed thereon, and
an image processor coupled to the camera and which, in operation:
extracts a first image of the conveyor out of the image captured by the camera;
in a second image other than the first image out of the image, detects a person included in the second image and applies mask processing to the person in the second image;
extracts a third image of a location at which a person is continuously present out of the second image and applies mask processing to the location; and
outputs a composite image of the first image, the second image minus the third image, and the third image to a display, where the first image shows the conveyor, the second image minus the third image shows the area surrounding the conveyor in which the person is masked, and in the third image the location at which a person is continuously present is masked.
