摘要： Provided is a calibration device that can calculate the mounting state of a stereo camera without the placing of a physical marker. In this device, an area setting processor (113) preliminarily sets, for an integrated image in which a road surface image region and a setting-prohibited region are integrated, an arrangement pattern having a plurality of area setting frames, and adjusts the arrangement pattern so that the plurality of area setting frames recede from each other. An extraction processor (114) extracts from distance images a plurality of partial images corresponding to the plurality of area setting frames. A mounting-state calculation unit (104) calculates a mounting-state parameter on the basis of a plurality of partial images, such parameter relating to the mounting state of a stereo camera used to pick up stereo images.

摘要： To reduce the amounts of HC, NOx and other emissions from a direct injection engine when a catalyst is still in its unheated state, and to promote catalyst quick light-off operation by increasing the temperature of exhaust gases, a control device comprises a temperature state identifier (31) for judging the temperature state of a catalyst (22) and a fuel injection controller (33) for controlling fuel injection from an injector (11). The fuel injection controller (33) controls the injector (11) based on judgment results of the temperature state identifier (31) in such a way that the injector (11) makes at least two-step split injection during a period from an intake stroke to an ignition point including a later injection cycle performed in a middle portion of a compression stroke or later and an earlier injection cycle performed prior to the later injection cycle at least in a low-load range of the engine when the catalyst (22) is in its unheated state, in which its temperature is lower than its activation temperature, and either of the later injection cycle and earlier injection cycle injects fuel which contributes to main combustion during a main combustion period in which approximately 10% to 90% by mass of the injected fuel is burnt in a combustion process occurring in the combustion chamber.

摘要： A stereo camera implements ranging of an object that includes consecutive similar patterns. In stereo matching using the stereo camera, if a plurality of corresponding point candidates are present in a sum of absolute differences (SAD) or suchlike evaluation value distribution for a target point, an evaluation value map is generated by superimposing an evaluation value distribution of a target point for which a plurality of corresponding points are determined to be present and an evaluation value distribution of each other target point present in a peripheral area of that target point. By this means, the shape of an object is represented in real space around a target point for which a plurality of corresponding points are determined to be present, and it is possible to calculate the true distance of a railing or the like that extends in a straight line by extracting a line segment with the strongest linearity in the evaluation value map.
