Provided is a technology for helping safe driving and realizing automatic driving of vehicles, or for counting the number of passing vehicles on the road or monitoring those passing vehicles for their driving. Using a plurality of cameras mounted in a vehicle or provided above a road, even if the relationship between the road plane and the respective cameras constantly changes in relative position or posture due to camera vibration or a change in road tilt, any obstacles located on the road such as other vehicles ahead, parked vehicles, and pedestrians on the road are detected without confusing those with textures including white lines, road signs, paint, road stains, and shadows of roadside objects, all of which do not disturb vehicle driving. An obstacle detection device 10 is structured by an image input section 11 for receiving images from a plurality of image pick-up devices 101, a correspondence detection section 12 for finding a plurality of pairs of corresponding points from the received right and left images, the slope degree calculation section 13 for calculating a slope degree of a plane including the corresponding points, and a result determination section 14 for determining as there being an obstacle when the calculated slope degree is larger than a predetermined value.

A vehicle driving assistance apparatus has an image capturing system capturing a road on which the vehicle travels, a white line type recognition section recognizing a type of a white line that defines a current traffic lane on which the vehicle is travelling on the basis of an image captured by the image capturing system, a white line type storage section storing the white line type recognized by the white line type recognition section, a white line type estimation section and a vehicle control system.

Besides, light reflection/emission regions (hatched portions in FIG. 4) are detected by detecting light regions of reflection, such as white lines, reflectors, etc., and light regions of light emission, such as street lights or the like, are detected. Then, divided regions corresponding to light distribution region irradiated by the headlights (12) which correspond to the detected light reflection/emission regions are specifically determined, and the headlights (12) are controlled so that the light radiated to the specifically determined divided regions 22 becomes dark in light distribution relative to other regions.

When a travel path is to be generated for a vehicle, road surface lines (white lines, etc.) delimiting the traffic lane of the vehicle, and also external objects in the vehicle environment, are detected and registered as respective obstacles. Specific points are defined at appropriate locations on each obstacle, and the travel path is generated by connecting respective mid-point positions between opposed pairs of specific points, each pair defined on respective ones of an opposed (left-side, right-side) pair of the registered obstacles.

A fixed data memory stores data of a normal lane width between lane lines and a narrow lane width between inner guide lines of double white lines. A lane-line candidate setting section detects lane-line detection points on both sides of a driving lane using a captured image, and sets lane-line candidate points on the opposite lane lines at spaces of the widths and therebetween, using the detection points as starting points. A curve approximation processing section sets virtual lines on both sides of the driving lane from a curve approximation equation obtained using the detection and candidate points. A lane-line position setting section obtains dispersions of the candidate points to the left and right virtual lines, and estimates the type of at least one of the left and right virtual lines.

Methods and apparatus for facilitating detection of a presence or an absence of at least one underground facility within a dig area. Source data representing one or more input images of a geographic area including the dig area is electronically received at a first user location, which may be remote from the dig area.

One or more indicators are added to the displayed input image(s), via a user input device associated with the display device, to provide at least one indication of the dig area and thereby generate a marked-up digital image. In the case of a staged excavation project, the input image, or a plurality of associated images, may include indicia of multiple dig areas corresponding to multiple stages of the staged excavation project.

A vehicle includes: an image acquisition means (4) which acquires a road image via an imaging means (3); an edge extraction means (5) which extracts edge points from the acquired image; a line search means (6) which searches the extracted edge points for line components; an evaluation value calculation means (7) which calculates an evaluation value indicating the degree that each line component approximates a linear lane mark on the road for the line components searched for; a lane mark candidate selection means (8) which selects line components each having an evaluation value greater than a predetermined threshold value as candidates for a line component corresponding to the lane mark from the line components searched for; and a lane mark detection means (9) which detects the lane mark by determining the line component corresponding to the lane mark from the selected candidates for the line component. This allows the detection accuracy to be increased by preventing an object other than a lane mark on the road from being incorrectly detected as a linear lane mark such as a white line when detecting a linear lane mark such as a white line from the road image.

An ink jet printing apparatus and an ink jet printing method are provided which, when printing small ink droplets at high resolution, can make white lines caused by an “end dot deflection” less visually conspicuous. To that end, an ink jet print head used has a plurality of nozzle substrates H1100 so arranged that an overlapping region in which the printable areas of respective nozzle substrates partly overlap is formed.
