    摘要: An image analysis section executes instruction processing to image electronic component while changing a shutter speed of measurement camera between a predetermined lower limit speed and a predetermined upper limit speed calculation processing of comparing an image of lower surface of each lead included in each of multiple imaging data acquired from the measurement camera with an ideal image of lower surface of each lead included in ideal imaging data to calculate a missing rate at which the image of lower surface of each lead is missing with respect to the ideal image for each of the multiple imaging data, detection processing of detecting imaging data having a missing rate equal to or less than a predetermined first threshold among multiple missing rates calculated by the calculation processing, and selection processing of selecting a shutter speed used for capturing the imaging data detected by the detection processing.

    摘要: A lane line detection method applied to a vehicle-mounted device is provided. In the method, the vehicle-mounted device converts a foreground image into a bird's-eye view (BEV) image, sets a peak of a horizontal histogram of the BEV image as a starting point for moving the sliding window, and generate a main lane line by fitting multiple non-zero pixels of the horizontal sliding window. The vehicle-mounted device calculates a confidence coefficient of each horizontal sliding window; and sets a previous one before the preset number of continuous horizontal sliding windows as a previous horizontal sliding window and determines an end point of the main lane line according to the previous horizontal sliding window when the confidence coefficients of preset number of continuous horizontal sliding windows are less than a predetermined threshold. The method improves accuracy of identifying lane lines.
