Methods and apparatus to monitor environments
First Claim
1. A method, comprising:
- analyzing, by executing an instruction with a processor, a plurality of three-dimensional data points having respective depth values representative of distances from a sensor of an environment;
when a first set of the three-dimensional data points has a first depth value satisfying a threshold, executing, by executing an instruction with the processor, a three-dimensional recognition analysis on a first area of the environment corresponding to the first set of the three-dimensional data points; and
when a second set of the three-dimensional data points has a second depth value not satisfying the threshold, executing, by executing an instruction with the processor, a two-dimensional recognition analysis on a second area of the environment corresponding to a first set of two-dimensional data points representative of at least a portion of the environment corresponding to the second set of three-dimensional data points.

Abstract
Methods and apparatus to monitor environments are disclosed. An example method includes analyzing, with a processor, a plurality of three-dimensional data points having respective depth values representative of distances from a sensor of an environment; when a first set of the three-dimensional data points has a first depth value satisfying a threshold, executing, with the processor, a first type of recognition analysis on a first area of the environment corresponding to the first set of the three-dimensional data points; and when a second set of the three-dimensional data points has a second depth value not satisfying the threshold, executing, with the processor, a second type of recognition analysis different than the first type of recognition analysis on a second area of the environment corresponding to the second set of the three-dimensional data points.
