Patent number: 8855417Abstract: When an image is captured in a wood lumber measuring mode, a distance to wood lumber is detected. An area extracting unit 51 for a component drawing image area extracts component image areas 53A-53L of the wood lumber. A drawing generator 61 for a component drawing image selects the component image areas 53A-53L successively to generate a component drawing image 62. Among shape lines in the component drawing image 62, an eliminator 66 eliminates a paracentral shape line 71, an edge side shape line 72, a peripheral shape line 73 and determined shape lines 74. If a total pixel number of a portion where an estimated elliptical shape 76 generated by a shape estimation unit 67 is overlapped on a residual shape line 75 disposed inside a corrected drawing image 64 is more than a threshold, it is judged that the estimated elliptical shape 76 is correctly shaped. An object shape determining unit 83 extracts the estimated elliptical shape 76 as a shape of wood lumber.Type: GrantFiled: May 24, 2011Date of Patent: October 7, 2014Assignee: FUJIFILM CorporationInventors: Tomonori Masuda, Eiji Ishiyama

Publication number: 20130002826Abstract: Appropriate selection of calibration data by shortening process time without wasteful processing is provided. Before measuring a three dimensional point of a target object from a stereo image, the calibration data according to an in-focus position of taking optical systems are applied to the stereo image. To select the calibration data, an object distance is acquired according to parallax obtained from the stereo image being reduced. The object distance is an estimated focusing distance corresponding to the in-focus position. One of the calibration data assigned with a set distance region in which the estimated focusing distance is included is selected. Respective view images are reduced in a range in which it is possible to detect any one of the set distance regions determined for a respective reference focusing distance corresponding to the calibration data.Type: ApplicationFiled: April 1, 2011Publication date: January 3, 2013Inventors: Eiji Ishiyama, Tomonori Masuda
