3D TRACKED POINT VISUALIZATION USING COLOR AND PERSPECTIVE SIZE

摘要

One exemplary embodiment involves receiving a plurality of three-dimensional (3D) track points for a plurality of frames of a video, wherein the 3D track points are extracted from a plurality of two-dimensional source points. The embodiment further involves rendering the 3D track points across a plurality of frames of the video on a two-dimensional (2D) display. Additionally, the embodiment involves coloring each of the 3D track points wherein the color of each 3D track point visually distinguishes the 3D track point from a plurality of surrounding 3D track points, and wherein the color of each 3D track point is consistent across the frames of the video. The embodiment also involves sizing each of the 3D track points based on a distance between a camera that captured the video and a location of the 2D source points referenced by the respective one of the 3D track points.

1. A computer-implemented method comprising:
receiving a plurality of three-dimensional (3D) track points for a plurality of frames of a video; determining respective colors and sizes to render a plurality of the 3D track points by:
determining a respective color to render a respective 3D track point to visually distinguish the respective 3D track point from colors of 3D track points that lie within a threshold distance of the respective 3D track point; anddetermining a respective size to render the respective 3D track point based on a distance between a camera that captured the video and a location referenced by the respective 3D track point; rendering the plurality of 3D track points according to the determined colors and sizes for a frame of the video on a two-dimensional (2D) display; and receiving input specifying an insertion location among the rendered 3D track points for insertion of a 3D object into the video.
