Abstract: In the system to collect image data for expressway inspection according to the present invention, in an automobile running on an expressway, a local area network including a shooting means, a storage means, an image extraction means, a positional information acquisition means, and a wireless communication means is constructed. The shooting means shoots still images at predetermined time interval, and for each time the shooting is performed, outputs the obtained image data to the storage means. The storage means recognizes positional information acquired at the timing of shooting the image data from the positional information acquisition means as shooting location, and stores the image data in relation with the shooting location.

Abstract: An object is to provide a pavement condition rating system which utilizes a road surface image based on perspective and which is extracted from a moving image obtained by traveling while photographing a road surface of a road, makes it possible to use the whole of an image area of a road surface included in a road surface image for detection of damage, and is less susceptible to damage erroneous detection. By using a plurality of images obtained by combining image of damage included in a road surface still image based on perspective and definitions of the damage as damage learning data, an object detection model is built.

Abstract: An electronic control apparatus is used for a power supply system that includes a rotating electric machine, a power generation control unit, first and second storage batteries, first and second switches, and a host control unit. The electronic control apparatus determines whether a predetermined process completion condition is met, without communicating with the host control unit, after an ignition switch of a vehicle is switched from an on state to an off state. The process completion condition indicates that a predetermined switch-off process is completed. The switch-off process is performed by the power generation control unit after the ignition switch is switched from the on state to the off state. The electronic control apparatus maintains the first switch in on state until determined that the process completion condition is met after the ignition switch is switched from the on state to the off state.
