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.
