The invention discloses an automatic detection method for redundancy and pin shrinking and reversing defects of an electric connector, and the method comprises the following steps: 1, carrying out the collection of an image in a hole cavity of the electric connector through a CMOS camera under the irradiation of a light source, and obtaining an image in the hole cavity of the electric connector; 2, generating an original code stream from the image in the hole cavity of the electric connector acquired in the step 1, transmitting the original code stream into a receiving decompression module through a control system, and decompressing the original code stream by the receiving decompression module to obtain image/video data; and step 3, performing video image data preprocessing on the image/video data obtained in the step 2, performing format conversion on the preprocessed image/video data, and finally generating the format-converted image/video data which can be accepted by the detection network.
