A surroundings monitoring system for a working machine prevents its own vehicle shadow from having an influence on the detection of an object existing around the working machine. The surroundings monitoring system for a working machine includes: a monocular camera picks up an image of the surroundings of the working machine. A characteristic pattern extraction unit extracts characteristic patterns in the picked-up image based on a characteristic amount of the image. A shadow profile extraction unit extracts a profile of a region, which can be regarded as a shadow of the working machine in the image, based on the characteristic amount of the image; and an object detection unit detects an obstacle existing around the working machine based on the remaining characteristic patterns obtained by excluding a shadow profile characteristic patterns positioned on the profile extracted by the shadow profile extraction unit from the characteristic patterns.

Surroundings monitoring system for working machine

In a video surveillance system, confirming videos from plurality of cameras causes a heavy burden on surveillance officers, and it is difficult to select a suitable video for observation. A video surveillance system includes a plurality of cameras which pick up images in a surveillance area, and a recognition unit which detects an object from videos acquired by the plurality of cameras. In the case where an object is detected in a surveillance area where images are picked up duplicately by the plurality of cameras, the recognition unit acquires a recognition result that is a feature quantity of the object for each camera. A display selection unit is, provided which, on the basis of the recognition result and a degree of priority of the recognition result, prioritizes the video from each of the cameras according to the degree of priority.

Surveillance camera control device and video surveillance system

An object detecting device includes an image acquiring unit which acquires an image from a camera, a scanning interval calculating unit which calculates a scanning interval when a scanning window is scanned on the image based on a size on the image of a detection object that is detected by the detecting window, a scanning unit which scans on the image using the scanning interval that is calculated by the scanning interval calculating unit, and a detecting unit which determines whether the detection object is present within the scanned detecting window.

Object detecting device and object detecting method

This invention includes: an obstacle detection unitthat detects obstacles present around the working machine, by use of an image acquired by a camera; a position calculating unitthat calculates positions of each of the detected obstacles; a hazard zone calculating unitthat calculates a hazard zone based upon an attitude and motion of the working machine; a determining unitthat determines whether further obstacles are present in the calculated hazard zone; a risk level setting unitthat sets a contact risk level for each of any obstacles present in the hazard zone; an image generating unitthat converts the camera image into a bird's-eye image centering upon the working machine, and then generates an image inclusive of all elements of the working machine and hazard zone on the bird's-eye image by further imaging the bird's-eye image diagonally from above an obstacle for which the highest contact risk level has been set by the risk level setting unit; and a display devicethat displays the generated image. This configuration makes an operator instantly recognize a position of the most potentially hazardous obstacle relative to the working machine, and thus improves working efficiency of the machine.

Peripheral monitoring device for working machine

A device which can support a determination of a camera layout by automatically preparing the camera layout that satisfies a customer request based on the customer request including a surveillance layout. Specifically, a need table that is a data set of a plurality of arrangement candidate cameras satisfying the customer request is prepared from the customer request including the surveillance layout. An arrangement of the plurality of the arrangement candidate cameras on a map is calculated based on the need table using a clustering method and a temporary layout of cameras is prepared. Then, an arrangement layout of the cameras in the surveillance layout is determined based on the temporary layout.

Camera layout determination support device

Provided is an in-vehicle image display device capable of providing, from among images of the peripheral area of a vehicle that can change in accordance with the driving state, an image of a part needed by the driver at an appropriate timing so that the driver can recognize the positional relationship between the vehicle and the peripheral area of the vehicle. Images captured with in-vehicle cameras are acquired, and a vehicle periphery image is generated from such images. Then, a collision-warned part of the vehicle that has a possibility of hitting a nearby object is selected based on the vehicle driving state, and the acquired image is processed to generate an enlarged image of the peripheral area of the collision-warned part of the vehicle selected by the collision-warned part selection part. Then, a composite display image, in which the positions of the enlarged image and the vehicle periphery image are displayed in a correlated manner, is generated and displayed.

In-vehicle image display device

There is provided apparatus for vehicle surroundings monitorings that assists so as to make it possible for a driver to check the periphery of the vehicle with ease. Plural images are obtained by capturing the periphery of the vehicle with mutually differing exposure. A process of image recognition is then performed for a target within the thus obtained images. The images are then compared, and images for which the accuracy of image recognition of the target is favorable are selected from among the images. The selected images are joined and composited to generate a host vehicle periphery composite image. Thus, an image with a wide dynamic range and high visibility is generated, thereby making it easier for the driver to check the periphery of the vehicle.

Apparatus for vehicle surroundings monitoring

In an advanced-cruise-assist highway system, an AHS center facility, which is an upper facility for on-road facilities, periodically receives diagnostic information from the on-road facilities, and when it is determined that any on-road facility is in the faulty state, communicates the information that the on-road facility is in the faulty state to on-road facilities upstream from the faulty on-road facility, and the on-road facilities having received the information on the fault in the downstream on-road facility communicates the information that the downstream on-road facility is in the faulty state via a road-to-vehicle communication facility to AHS vehicles having the possibility of entering a zone under control by the faulty on-road facility. Further the information that the downstream on-road facility is in the faulty state is displayed on information board which can be recognize by vehicles having the possibility of entering a zone under control by the faulty on-road facility.

On-road facility fault information communication apparatus

A traveling support information processing unit which can prevent willful assessment of information by a device installed on a road or loaded in a vehicle and makes it possible for the device to always issue a demand for acquisition of required information or a demand for consultation for cooperated determination, and which does not require any specific and additional device for acquisition of positional information for each vehicle and also can improve safety and efficiency in road utilization. In a computer system, vehicles 114A to 114C, 115C, and 115D with the behaviors on a road such as acceleration, deceleration, and lane change projected are made to run on a road 113 simulating the road structure. Communication is performed between a function 101 for tracking or projecting behaviors of the vehicle and the vehicles 115A, 115B having a communicating function.
