Chip reference point positioning method and device, computer equipment and storage medium

The invention discloses a chip reference point positioning method and device, computer equipment and a storage medium, and belongs to the technical field of machine vision and semiconductor detection. The invention provides a chip datum point positioning method and device, computer equipment and a storage medium, and aims to solve the problems that in the prior art, chip datum point positioning steps are tedious, and a chip datum point cannot be accurately positioned due to the fact that the chip datum point positioning steps are easily affected by noise. The test image is convolved by using the convolution kernel to obtain a convolution result image, the maximum pixel value of the reference point of the test image is searched in the convolution result image, the coordinate of the maximum pixel value is calculated, and the position of the reference point of the test image is obtained, so that under the condition that the reference point of the chip has noise interference or slight deformation, the reference p
