DETERMINING POSITIONAL INFORMATION OF AN OBJECT IN SPACE

摘要

The technology disclosed relates to determining positional information of an object in a field of view. In particular, it relates to calculating a distance of the object from a reference such as a sensor including scanning the field of view by selectively illuminating directionally oriented light sources and measuring one or more differences in property of returning light emitted from the light sources and reflected from the object. The property can be intensity or phase difference of the light. It also relates to finding an object in a region of space. In particular, it relates to scanning the region of space with directionally controllable illumination, determining a difference in a property of the illumination received for two or more points in the scanning, and determining positional information of the object based in part upon the points in the scanning corresponding to the difference in the property.

主权项

1. A method of determining positional information of a target object in a field of view, the method including:
scanning a field of view by selectively illuminating respective ones of a plurality of directionally oriented light sources that have overlapping fields of illumination; measuring one or more differences in intensity of returning light emitted from the respective light sources and reflected from the target object using a sensor; and determining positional information of the target object based at least in part upon one or more measured differences in intensity of the returning light.
