The invention discloses a vehicle body model construction method and apparatus, an electronic device and a storage medium. The method comprises the steps of obtaining a first visible point cloud of a target vehicle; calculating a dense model of the target vehicle and features of the dense model based on the first visible point cloud; obtaining at least one frame of second visible point cloud of the target vehicle, and fusing the second visible point cloud with the first visible point cloud to obtain a target visible point cloud of the target vehicle and an invisible point cloud of the target vehicle; and constructing a target function based on the invisible point cloud, the target visible point cloud and the characteristics of the dense model, and optimizing the target function to obtain the characteristics of the optimized dense model so as to determine the optimized dense model. According to the method, the movement of the target vehicle is considered, the multi-frame point cloud fusion is combined, the gen
