description	The invention discloses a logging image card recognition and dip angle correction method and device and computing equipment, according to the technical scheme provided by the invention, ultrasonic imaging logging is carried out in a target depth interval in a well, and an original amplitude image and an original travel time image are obtained; processing the original travel time image to obtain a jamming indication curve of the target depth interval; according to a preset threshold value, determining the length of a card meeting depth section in the card meeting indication curve, and according to the length of the card meeting depth section, carrying out stretching processing on the original amplitude image to obtain a corrected amplitude image of the target depth interval; and performing inclination angle identification and correction on the correction amplitude imaging to obtain a target inclination angle value. According to the method, a jam indication curve can be obtained based on analysis of original lo
