Abstract
Methods and apparatus to monitor environments are disclosed. An example method includes analyzing a plurality of three-dimensional data points having respective depth values representative of distances between a sensor and respective objects of an environment; when a first set of the three-dimensional data points has a first depth value less than a threshold, executing 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 greater than the threshold, executing 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.
