Embodiment 1
[0084] like Figure 1 to Figure 7 As shown, a chip character anti-jamming recognition method comprises the following steps:
[0085] (1) Adjust the brightness of the light source and move the camera position so that the contrast between the characters on the chip and the background is as follows figure 2 effect, the outline of characters is clearly visible;
[0086] (2) The template of the IC chip to be recognized is called from the chip template library, and the camera captures a frame of IC chip image, based on the called template, the chip template is searched in the entire area of the collected image, and two data are output after the template is matched, namely The position and direction of the template matching, this direction is the Angle of the placement direction of the chip, set the correct placement angle to 0°, if |Angle|>5°, it is judged that the placement direction of the chip is wrong, in the display software The interface prompts that the direction is wron...
Embodiment 2
[0118] like Figure 8 As shown, a chip character anti-interference recognition device includes a detection device 1, a light source 2, an image acquisition device 3, a display device 4, a visual processing device 5, an alarm device 6 and a multilayer perceptron.
