Publication number: 20240080421Abstract: An apparatus includes a first camera configured to capture a first image being displayed, a second camera configured to capture a second image being displayed, and a processor configured to generate a pair-wise homography transform for the first camera and the second camera, and map, based on the pair-wise homography transform, the second image from a second frame of reference of the second camera to a first frame of reference of the first camera. The processor is further configured to determine a first corrected quadrilateral for the first image and a second corrected quadrilateral for the second image in the first frame of reference, and project, based on the pair-wise homography transform, the second corrected quadrilateral from the first frame of reference to the second frame of reference. The quadrilaterals are then processed to warp respective images for geometric correction before projecting the images by respective projectors.Type: ApplicationFiled: June 30, 2023Publication date: March 7, 2024Inventors: Shivam SRIVASTAVA, Jaime Rene DE LA CRUZ VAZQUEZ, Jeffrey Matthew KEMPF

Patent number: 11592732Abstract: In described examples, a geometric progression of structured light elements is iteratively projected for display on a projection screen surface. The displayed progression is for determining a three-dimensional characterization of the projection screen surface. Points of the three-dimensional characterization of a projection screen surface are respaced in accordance with a spacing grid and an indication of an observer position. A compensated depth for each of the respaced points is determined in response to the three-dimensional characterization of the projection screen surface. A compensated image can be projected on the projection screen surface in response to the respaced points and respective compensated depths.Type: GrantFiled: May 5, 2020Date of Patent: February 28, 2023Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Jaime Rene De La Cruz, Jefferey Mathew Kempf

Patent number: 11258997Abstract: In described examples, structured light elements are projected for display on a projection screen surface. The projected light elements are captured for determining a three-dimensional characterization of the projection screen surface. A three-dimensional characterization of the projection screen surface is generated in response to the displayed structured light elements. An observer perspective characterization of the projection screen surface is generated in response to an observer position and the three-dimensional characterization. A depth for at least one point of the observer perspective characterization is determined in response to depth information of respective neighboring points of the at least one point of the observer perspective characterization. A compensated image can be projected on the projection screen surface in response to the observer perspective characterization and depth information of respective neighboring points of the at least one point of the observer perspective characterization.Type: GrantFiled: May 1, 2020Date of Patent: February 22, 2022Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Jaime Rene De La Cruz, Jeffrey Mathew Kempf

Patent number: 9769443Abstract: A system and method for facilitating keystone correction in a given model of projector having an attached camera is disclosed. System calibration determines intrinsic and extrinsic parameters of the projector and camera; then control points are identified within a three-dimensional space in front of a screen. The three-dimensional space defines a throw range and maximum pitch and yaw offsets for the projector/screen combination. At each control point, the projector projects a group of structured light elements on the screen and the camera captures an image of the projected pattern. These images are used to create three-dimensional look-up tables that identify a relationship between each image and at least one of (i) pitch and yaw offset angles for the respective control point and (ii) a focal length and a principal point for the respective control point. The given model projectors use the tables in effectuating keystone correction.Type: GrantFiled: December 11, 2015Date of Patent: September 19, 2017Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Jaime Rene De La Cruz, Jeffrey Mathew Kempf, Ramzansaheb Nadaf
