The invention provides a wheel tread and out-of-roundness measuring method and device, a terminal and a storage medium. The method comprises the following steps: respectively acquiring real-time images acquired by a first acquisition device and a second acquisition device; performing noise filtering processing on the real-time image to obtain a noise-reduced image; cutting the noise-reduced image to obtain a cut image containing the key area; performing three-dimensional reconstruction on the cut image to obtain a three-dimensional reconstruction model; and acquiring the minimum horizontal distance between the first acquisition device and the tread of the to-be-measured wheel, and determining the tread size and out-of-roundness of the to-be-measured wheel according to the minimum horizontal distance and the three-dimensional reconstruction model. According to the invention, the wheel tread and out-of-roundness measurement efficiency can be improved. 本发明提供一种车轮踏面和不圆度的测量方法、装置、终端及存储介质。该方法包括：分别获取第一采集设备和第二采集设备所采集的实
