  • Patent number: 8212869
    Abstract: A substrate inspection method capable of accurately inspecting a substrate is provided. A jig having reference points represented by known coordinates in a three-dimensional world coordinate system is photographed by a camera and coordinates of the reference points in a pixel image coordinate system defined by pixels of an image forming device is determined. The coordinates in the pixel image coordinate system are transformed into those in a camera coordinate system set on the camera, and world-camera coordinate system transformation parameters are calculated. Image data in the pixel image coordinate system obtained by photographing a substrate to be inspected is transformed into image data in a world coordinate system for inspection. The accurate inspection of the substrate to be inspected can be achieved because distortion in the image of the substrate to be inspected in the world coordinate system attributable to the position and attitude of the camera is reduced.

  • Patent number: 7821535
    Abstract: Indices are detected from a pattern image including a plurality of indices, and first positions of the detected indices on the captured image are calculated. Using parameters associated with an image capturing apparatus, second positions indicating the positions of the indices on the captured image are calculated. While a parameter of a radial distortion of a lens of the image capturing apparatus is fixed, the parameters other than the parameter of the radial distortion of the lens of the image capturing apparatus are corrected using the differences between the first positions and the second positions. Using the corrected parameters, third positions indicating the positions of the indices on the captured image are calculated. Using the differences between the first positions and the third positions, the parameter of the radial distortion is corrected.

  • Patent number: 7777807
    Abstract: An on-board object detector and on-board object detection method for detecting an object present in a pickup image at a high level of precision. A controller controls a projector to irradiate a line of light while shifting the irradiation angle, and images in the coverage area of the line of light are captured for multiple frames using a camera. Then, shifts in the moving speed of the line of light in the images across the frames are computed based on the images captured, and shifting points in the moving speed of the line of light are detected based on the computed shifts in the moving speed of the line of light in the images across the frames. The position and size of an object that is present in the images are specified based on said detected shifting points in the moving speed of the line of light.

  • Publication number: 20100141755
    Abstract: A substrate inspection method capable of accurately inspecting a substrate is provided. A jig having reference points represented by known coordinates in a three-dimensional world coordinate system is photographed by a camera and coordinates of the reference points in a pixel image coordinate system defined by pixels of an image forming device is determined. The coordinates in the pixel image coordinate system are transformed into those in a camera coordinate system set on the camera, and world-camera coordinate system transformation parameters are calculated. Image data in the pixel image coordinate system obtained by photographing a substrate to be inspected is transformed into image data in a world coordinate system for inspection. The accurate inspection of the substrate to be inspected can be achieved because distortion in the image of the substrate to be inspected in the world coordinate system attributable to the position and attitude of the camera is reduced.

  • Patent number: 7702131
    Abstract: A sequence of images depicts a foreground object in motion. A base image is selected, and the other images in the sequence are co-registered with the base image in order to align the images to a common coordinate system. A background image and a binary foreground mask are generated from the sequence of aligned images. By applying the foreground mask to a chosen one of the aligned images, a representation of the moving object is extracted. After blurring the background image, the extracted representation may be superimposed onto the blurred background image to produce a new image.
