Abstract: Embodiments of the present disclosure provide a three-dimensional reconstruction method. Mark points are set on a surface of a target object. Then, multiple frames of mark point three-dimensional point cloud are reconstructed based on image frames containing a mark point pattern, and multiple frames of target object three-dimensional point cloud are reconstructed based on image frames containing a structured light pattern. As a coordinate transformation relationship between the multiple frames of the three-dimensional point cloud can be accurately determined, and a coordinate transformation relationship between a single frame of the mark point three-dimensional point cloud and a single frame of the target object three-dimensional point cloud can also be determined, the mark points can further be used to assist in stitching the multiple frames of the target object three-dimensional point cloud, to obtain a more accurate stitching result.

Abstract: Systems and methods are described herein for select content for bid-processing and content placement online placement resources. A computer in an RTB bidding process transmits the selected content to an identified online resource that satisfies the various (and often competing) goal objective thresholds and budget thresholds. The computer transmits the content to the identified online resource, which forwards or transmits the campaign content for display at a user interface of an end-user. The computer analyzes historical data to evaluate the performance of content campaigns against multiple user-selected performance goals and priorities to determine whether to bid for content placement at a given online resource. The computer may generate a blocklist to reject placements at underperforming online resources. The computer may perform optimization functions to determine optimal bid prices that balance the goal objective thresholds and budget threshold and determine whether to bid for the placement.
