The invention relates to the technical field of lamp filament illumination, in particular to a lamp filament quality intelligent detection method based on computer vision, which comprises the following steps: acquiring a lamp filament detection image and a lamp filament template image so as to obtain each target key point pair, each target detection key point and each target module key point; determining a direction correction coefficient and a distance correction coefficient, and further determining a first matching probability and a second matching probability; counting the total number of the key points which are not successfully matched according to the matching degree determined by the first matching probability and the second matching probability; and judging whether the to-be-detected lamp filament is bent or not according to the total number of the key points which are not successfully matched. According to the invention, through the corresponding matching degree when each target detection key point i
