The invention discloses an online visual detection method, which comprises the following steps of: 1) inputting a recognition image array into a memory included in a processor; step 2), inputting a weight array into the input memory; step 3), photographing the object to obtain product image data, arranging the obtained product image data into a product image array by a processor, and storing the product image array in a memory; 4) calling out the product image array and the weight array from the memory by the processor, and processing the product image array and the weight array in an array pulsation form to obtain a comparison result; and 5) performing similarity comparison on the comparison result and the recognition image array. According to the online visual detection method, the product image data array and the weight array are input into the operation unit at one time, elements in the product image array and the weight array are multiplied and then accumulated, the processor only needs to call data from the memory for one time to execute operation, repeated registering and calling are not needed, and the image recognition speed is high.
Description
technical field [0001] The invention relates to the field of visual detection, in particular to an online visual detection method. Background technique [0002] In the process of automated production, in order to ensure the stability of continuous production, it is necessary to design multiple tests on the production line. When performing visual inspection, the current method is usually to configure the CCD module to take pictures of the products on the production line, and then compare the pictures with the pictures pre-stored in the memory of the CCD module. When comparing, the processor in the CCD module needs to repeatedly call data from the memory of the CPU to perform operations when pre-processing the product image, and the image recognition speed is limited. SUMMARY OF THE INVENTION [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. [0004] The present invention provides an online visual detection metho...
