Patent number: 11922649Abstract: It provides the measurement data of each portion of the target object with a high accuracy. The measurement data calculation apparatus 1020 includes an obtaining unit 1024A, an extraction unit 1024B, a conversion unit 1024C, and a calculation unit 1024D. The obtaining unit 1024A obtains the image data in which the target object is photographed and the full length data of the target object. The extraction unit 1024B extracts the shape data indicating the shape of the target object from the image data. The conversion unit 1024C converts and silhouettes the shape data based on the full length data. The calculation unit 1024D uses the shape data converted by the conversion unit 1024C to calculate the measurement data of each portion of the target object.Type: GrantFiled: May 27, 2021Date of Patent: March 5, 2024Assignee: Arithmer Inc.Inventors: Daisuke Sato, Hiroki Yato, Chikashi Arita, Yoshihisa Ishibashi, Takashi Nakano, Ryosuke Sasaki, Ryosuke Tajima, Yoshihiro Ohta
