  • Publication number: 20250002007
    Abstract: A learning model is applied to estimate a parking spot definition rectangle (polygon), a parking spot entrance direction, and a vacancy state of a parking spot. A top surface image generated by combining individual images captured by front, rear, left, and right cameras mounted on a vehicle is analyzed, and analysis processing is performed on a parking spot in the image. A parking spot analysis unit uses a learning model to estimate a vertex of a parking spot definition rectangle (polygon) indicating a parking spot region in the image and an entrance direction of the parking spot. Furthermore, estimation is performed as to whether the parking spot is a vacant parking spot or an occupied parking spot in which a parked vehicle is present. The parking spot analysis unit uses CenterNet as a learning model to execute, for example, estimation processing on a spot center and a vertex of a parking spot definition rectangle (polygon).

  • Patent number: 12125237
    Abstract: The present technology relates to an information processing apparatus, an information processing method, a program, a mobile-object control apparatus, and a mobile object that make it possible to improve the accuracy in recognizing a target object. An information processing apparatus includes an image processor that generates an estimated-location image on the basis of a sensor image that indicates, in a first coordinate system, a sensing result of a sensor of which a sensing range at least partially overlaps a sensing range of an image sensor, the estimated-location image indicating an estimated location of a target object in a second coordinate system identical to a coordinate system of a captured image obtained by the image sensor; and an object recognition section that performs processing of recognizing the target object on the basis of the captured image and the estimated-location image. The present technology is applicable to, for example, a system used to recognize a target object around a vehicle.

  • Publication number: 20230040994
    Abstract: A processing load in a case where a plurality of different sensors is used can be reduced. An information processing apparatus according to an embodiment includes: a recognition processing unit (15, 40b) configured to perform recognition processing for recognizing a target object by adding, to an output of a first sensor (23), region information that is generated according to object likelihood detected in a process of object recognition processing based on an output of a second sensor (21) different from the first sensor.
