METHOD AND SYSTEM FOR OPTIMIZING SAMPLING IN SPOT TIME-OF-FLIGHT (TOF) SENSOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 17992296 titled 'METHOD AND SYSTEM FOR OPTIMIZING SAMPLING IN SPOT TIME-OF-FLIGHT (TOF) SENSOR
Simplified Explanation
The abstract describes a method for optimizing sampling in a spot Time-of-Flight (ToF) sensor. The method involves analyzing an image of a scene, dividing it into rectangular regions based on edge features, computing an edge region alignment for each region using Histogram of oriented Gradients (HoG) distribution, re-projecting ToF data onto a Complementary Metal Oxide Semiconductor (CMOS) Image Sensor (CIS) image plane, sampling rectangular regions based on regional depth variance, and reconfiguring the illumination pattern for the spot ToF sensor image frame using the sampled regions.
- The method optimizes sampling in a spot Time-of-Flight (ToF) sensor.
- The image of a scene is divided into rectangular regions based on edge features.
- Edge region alignment is computed for each rectangular region using Histogram of oriented Gradients (HoG) distribution.
- ToF data is re-projected onto a Complementary Metal Oxide Semiconductor (CMOS) Image Sensor (CIS) image plane.
- Rectangular regions are sampled based on regional depth variance compared to a threshold depth variance.

Original Abstract Submitted
A method for optimizing sampling in a spot Time-of-Flight (ToF) sensor includes receiving an image of a scene, dividing the image into plural rectangular regions, based on an edge feature in the image, computing an edge region alignment for each rectangular region by analyzing a Histogram of oriented Gradients (HoG) distribution corresponding to the rectangular region, re-projecting ToF data on a Complementary Metal Oxide Semiconductor (CMOS) Image Sensor (CIS) image plane according to the edge region alignment, sampling one or more rectangular regions from among the plural rectangular regions by comparing a regional depth variance of each rectangular region with a threshold depth variance, and reconfiguring an illumination pattern for a spot ToF sensor image frame using the one or more rectangular regions that are sampled.
