Abstract: A method, device, system and computer readable storage medium for 3D reconstruction are provided. The method includes: extracting original image features from an original 2D image of a target object; determining an original 3D object based on the original image features; determining a camera pose in the complementary view of the target object, where the complementary view is different from a first view in which the original 2D image is generated; generating a complementary 2D image of the target object in the complementary view based on the camera pose in the complementary view; performing 3D reconstruction based on the complementary 2D image to generate a complementary 3D object corresponding to the complementary 2D image; fusing the original 3D object and the complementary 3D object to obtain a 3D reconstruction result of the target object.

Abstract: Disclosed is a clamping device having an automatic direction adjustment function in a vehicle body welding conveying line, including a conveying frame. A driving motor is fixedly connected to a side wall of the conveying frame, and an output shaft end of the driving motor is fixedly connected to a rotating shaft I. The present disclosure facilitates the adjustment of a direction when vehicle bodies to be welded are conveyed on a turning conveying line, and vehicle bodies being conveyed can be corrected to the same horizontal state, to avoid a situation where the clamping device on the conveying line cannot smoothly clamp inclined vehicle bodies for conveying because the vehicle bodies cannot be in the same horizontal plane when being put in.

Abstract: A method, device, computer system and computer readable storage medium for 3D reconstruction are provided. The method comprises: performing a 3D reconstruction of an original 2D image of a target object to generate an original 3D object corresponding to the original 2D image; selecting a complementary view of the target object from candidate views based on a reconstruction quality of the original 3D object at the candidate views; obtaining a complementary 2D image of the target object based on the complementary view; performing a 3D reconstruction of the complementary 2D image to generate a complementary 3D object corresponding to the complementary 2D image; and fusing the original 3D object and the complementary 3D object to obtain a 3D reconstruction result of the target object.
