Patent number: 11467277Abstract: An object recognition apparatus groups reflection points detected by a radar device, and recognizes an object around the own vehicle, based on a radar-based target detected using the grouped plurality of reflection points and an image-based target detected using an image captured by an image capturing device. The object recognition apparatus includes a reflection point acquiring unit that acquires reflection point information related to the grouped plurality of reflection points, and an object determining unit that determines that a plurality of objects have been detected as a single object by the radar device, based on the reflection point information acquired by the reflection point acquiring unit and the information on the image-based target, if the image-based target detected by the imaging device includes an image-only target not detected by the radar device.Type: GrantFiled: March 29, 2017Date of Patent: October 11, 2022Assignees: DENSO CORPORATION, TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yohei Masui, Tadashi Sakai, Takashi Maeda, Takeshi Nanami, Minoru Nakadori

Patent number: 11086011Abstract: A target detection device mounted in a vehicle includes: a radar specification unit; a same target determination unit; and an image specification unit that specifies, as image target position information, an image detection region of an image detection target detected on the basis of a captured image, the image detection region representing the position of the image detection target relative to the base point on an XY-plane with the X-axis representing the vehicle width direction of the vehicle and the Y-axis representing the vehicle length direction of the vehicle. The image specification unit sets the Y-axis range of the image detection region in the Y-axis direction on the basis of the bearing from the base point to each of the two X-directional ends of the image detection target in the captured image and of an expected width minimum value and an expected width maximum value in the X-axis direction.Type: GrantFiled: May 19, 2017Date of Patent: August 10, 2021Assignees: DENSO CORPORATION, TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Tadashi Sakai, Yohei Masui, Ryoma Niihara, Takashi Maeda, Takeshi Nanami, Minoru Nakadori

Patent number: 11003927Abstract: In a target recognition apparatus that recognizes a target in a periphery of an own vehicle, a radar target acquiring unit acquires, as a radar target, the target that is detected by transmission and reception of radar waves. An image target acquiring unit acquires, as an image target, the target that is included in a captured image captured by an imaging apparatus. A target recognizing unit recognizes, as a first target, one of a plurality of radar targets included in a predetermined area relative to the image target and recognizes, as a second target, at least one of the plurality of radar targets other than the first target. A sameness determining unit determines whether the first target and the second target are the same object.Type: GrantFiled: September 7, 2018Date of Patent: May 11, 2021Assignees: DENSO CORPORATION, TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Tomohiko Inoue, Tadashi Sakai, Yohei Masui, Takashi Maeda
