This application relates to a defect inspection method, system and apparatus, a device, a storage medium, and a product. In response to an inspection instruction for a target material, a camera device is controlled to acquire a two-dimensional image and a three-dimensional image of the target material, and a defect inspection result of the target material is determined based on the two-dimensional image and the three-dimensional image of the target material. In this method, because the camera device is a structured light camera device integrating a two-dimensional image acquisition function and a three-dimensional image acquisition function, the two-dimensional image and the three-dimensional image can be acquired without the need of switching camera devices, improving the convenience of defect inspection of the target material. Moreover, the use of the same camera device to acquire the two-dimensional image and the three-dimensional image ensures that the two-dimensional image and the three-dimensional image are in the same coordinate system, improving the efficiency of defect inspection of the target material. In addition, the use of the two-dimensional image and the three-dimensional image in two different dimensions for defect inspection of the target material improves the accuracy of the defect inspection.
