  • Publication number: 20240078119
    Abstract: Function definition information is prepared in a system. The function definition information is information representing a correspondence relationship among a software-based function, a vehicle ID of a vehicle, a hardware configuration for implementing a function, and a software configuration for implementing a function. The system performs a preliminary determination including a determination of a relationship between one or a plurality of user-desired functions constituting a user-desired function group of a user and a hardware configuration of a target vehicle based on the function definition information. For each of the one or more functions specified in the preliminary determination, in order to implement the function in the target vehicle, the system develops a software configuration corresponding to the function in a hardware configuration corresponding to the function in the target vehicle.

  • Patent number: 10378877
    Abstract: The present disclosure relates to an image processing device that reduces the computation load in image processing, an image processing method, and a program. A rough-detection component detecting unit detects markers shown in an image. A marker selecting unit selects a predetermined number of markers from among the markers detected by the rough-detection component detecting unit. A specific-detection component detecting unit detects the predetermined number of markers selected by the marker selecting unit in a more specific manner than the rough-detection component detecting unit. An estimating/processing unit estimates positions and postures of the markers based on results of the detection performed by the specific-detection component detecting unit. The present technique can be applied to an image processing device that combines the background of a person captured by a camera with another background image.

  • Publication number: 20190005613
    Abstract: A coordinate transformation matrix generation unit 41 generates a coordinate transformation matrix corresponding to an image range obtained from a position and a direction of a viewpoint in a virtual space and the viewpoint. A scale transformation adjustment unit 42 performs a scale transformation corresponding to a change of an image range with respect to an actual image by using a scale transformation by an optical zoom of an image pickup unit that generates the actual image, and generates a coordinate transformation matrix including the scale transformation. An image synthesis unit 46 uses the coordinate transformation matrix generated by the coordinate transformation matrix generation unit 41 to perform coordinate transformation of a virtual image, uses the coordinate transformation matrix generated by the scale transformation adjustment unit 42 to perform coordinate transformation of the actual image, and synthesizes the virtual image and the actual image after the coordinate transformations.

  • Patent number: 9785839
    Abstract: The present invention relates to an image processing device, an image processing method, and a program, which combine an image with less sense of incongruity. A high accuracy marker detector and a high sensitivity marker detector each detects a marker on an image by a different detection method. The high accuracy marker detector detects the position and the posture of the marker with higher accuracy, and the high sensitivity marker detector has a lower accuracy to detect the marker than the high accuracy marker detector, but detects the position of the marker with high sensitivity by prioritizing detecting the marker. A detection result selector selects the optimal detection result from a plurality of the detection results. The present technique is applicable to, for example, an image processing device which replaces the marker with another image.
