In In order to solve the problem that the maximum frame frequency is used to take continuous shots when testing continuous projectile coordinates in CCD linear array intersection system, the processing time is too long due to the large amount of data. A fast coordinate detection method of continuous projectiles based on multi-peak detection and adaptive threshold detection based on laser curtain triggering is proposed.?A semiconductor laser with a divergence Angle of 90 degrees is used to form the photoelectric detection target with the primary reflection screen.Photovoltaic modules will projectile target when flux changes had a target signal into electrical signals, processing data to use multiple peak detection algorithm, according to the target signal waveform to calculate all the projectile location information of target point and the corresponding image, the image and adjacent two images spliced into a combination of the image as the hair of the projectile target image,Then the projectile detection algorithm based on adaptive threshold is used to detect the projectile target and obtain the projectile coordinates.?When multiple pixel coordinates are detected in the image, the pixel coordinate culling algorithm is used to get the accurate coordinates.?Finally, four groups of control experiments were carried out, and the processing time of the proposed method and the traditional method were calculated respectively on the premise of obtaining the correct continuous coordinate.?The results show that compared with the traditional method for processing all images, the method proposed in this paper can improve the processing speed on the premise of ensuring the accuracy of continuous projectile coordinates.
