  • Patent number: 7966127
    Abstract: The invention provides a vehicle motion control device capable of realizing optimum avoidance control in the case of an emergency. The vehicle motion control device includes an external environment detection unit for detecting external environment, and a travel state detection unit for detecting a travel state of a driver's vehicle. An obstruction is detected based on the external environment detected by the external environment detection unit, and an environment map indicating obstructions is created. A control device estimates a plurality of possible avoidance actions for avoiding an obstruction based on the environment map and the travel state of the driver's vehicle detected by the travel state detection unit. The control device estimates collision damage according to each avoidance action estimated by the avoidance action estimation unit, and selects an appropriate avoidance action based on the estimated collision damage.

    Abstract: A color image creating apparatus includes an acquisition unit and a creation unit. The acquisition unit acquires a color visible image from an imaging unit which images the color visible image which includes plural pixels which each include color information and intensity information based on light in a visible light range. The creation unit uses the intensity information and the color information which are acquired by the imaging for a pixel which has intensity equal to or higher than a predetermined value so as to effect display in color, and uses the intensity information acquired by the imaging for a pixel which has intensity lower than the predetermined value so as to effect display in grayscale, and create a color image.

  • Patent number: 7583817
    Abstract: An object determining apparatus is disclosed which is structured such that right and left disparity images are acquired from different view points, disparity of corresponding points in the right and left images is computed, information relating to the points for which disparity is computed is voted to respective blocks of a disparity map that arranges blocks with one side corresponding to disparity, other side corresponding to image lateral position, and these sides being elongated with increasing disparity. An attribute of three dimensional object is applied to first blocks in which distribution of voted disparity points in disparity direction is small and image vertical direction is large. An attribute of road surface is applied to second blocks in which distribution in disparity direction is large and image vertical direction small, thereby determining an object as a three dimensional object or road surface.
