  • Patent number: 10559076
    Abstract: Characteristic data of a relevant component is extracted from a component image captured by camera, and the extracted characteristic data is compared with reference characteristic data of multiple types of component registered in a database to distinguish a type of component for which the two sets of data match most closely. As a result of this, a power spectrum image is created by applying an FFT for each scanning line to a lead presence candidate region corresponding to a candidate for a lead being present in a component image distinguished as an odd form component. Further, an HLAC characteristic is calculated from the power spectrum image in order to extract a periodic characteristic of the power spectrum image, and a connector component with leads is distinguished from an odd form component by learning a characteristic amount of the LAC characteristic using an SVM.

  • Patent number: 10380457
    Abstract: An electronic component picked up and held by a mounting head of a component mounter is moved to an imaging position above a component imaging camera, the tip of the lead of the electronic component is imaged from below by the camera to acquire a lead image, and the lead image is inputted into an image recognition device configured from a neural network or the like and imaged processed so as to output the center position of the tip of the lead. Here, whenever an image processing error occurs, the lead image for which the image processing error occurred is displayed on a display device, and an operator specifies the center position of the tip of the lead in the lead image display on the display device and the specified center position is inputted into the image recognition device.

  • Patent number: 10102426
    Abstract: When recognizing leads by processing an image captured by a camera of a component provided with a single row or multiple rows of leads of the same size and shape at a regular pitch, waveform analysis of a change pattern of brightness (pixel value) along multiple lines set in a vertical, a horizontal, or a diagonal direction of the image is performed so as to identify a region in which the brightness changes cyclically as a lead recognition target region in which there is a possibility of a lead existing. Then, image recognition of leads is performed in the lead recognition target region.

  • Patent number: 9977967
    Abstract: The object detection device 1 detects an object being recognized (such as a pedestrian) in a frame image 42, and identifies an area 42a where a detected object which is detected in the frame image 42 is present. A frame image 43 is input after the frame image 42. The object detection device 1 detects the object being recognized in the frame image 43, and identifies an area 43a where a detected object which is detected in the frame image 43 is present. When a distance from center coordinates 42b of the area 42a to center coordinates 43b of the area 43a is smaller than a reference distance, the object detection device 1 determines that the detected object which is detected in the frame image 43 is identical to the detected object which is detected in the frame image 42.

  • Patent number: 7310433
    Abstract: An overlapped portion of a plurality of partial images of a fingerprint that are input from a fingerprint input device (7) is corrected to be reconfigured at a reconfiguration process section (106). The characteristics are extracted from the input partial images at the fingerprint characteristic information extracting section (110) and the extracted characteristic information is stored in an input characteristic information memory. A verification process section executes DP comparison (dynamic programming method) between the characteristic information stored in the input characteristic information memory and the characteristic information stored in the registered characteristic information memory. The distance value obtained by the DP comparison is compared to a threshold that is previously set. If the distance value is smaller than the threshold, it is judged the fingerprint is identified and if the distance value is larger than the threshold, it is judged that the fingerprint is not identified.

  • Patent number: 7133542
    Abstract: The present invention provides technologies for narrowing down fingerprints images, which will be used for identity determination, without extracting auxiliary information such as a fingerprint pattern, thereby shortening the time required for fingerprint verification. The device according to the present invention includes a storage means 26 for storing characteristic information extracted from fingerprint images of registered persons, and a collection means 10 for collecting a fingerprint image. First, a extraction means 14 extracts characteristic information from the fingerprint image collected by the collection means 10. Next, a narrowing means 16 calculates a similarity between part of the characteristic information of the person to be identified, which was extracted by the extraction means 14, and corresponding part of the characteristic information of each of the registered persons, which is stored in the storage means 26.
