SYSTEM AND METHOD FOR MONITORING AN INDIVIDUAL USING LIDAR
A system for monitoring an individual includes a processor and a LIDAR sensor in electronic communication with the processor. The processor is configured to receive a set of spatial data from the LIDAR sensor, calculate a first location of the individual relative to a support object based on the set of spatial data, and determine if the first location is at an alert location relative to the support object. In another aspect, a method for monitoring an individual includes receiving a first set of spatial data from a LIDAR sensor, calculating a first location of the individual relative to a support object based on the first set of spatial data, and determining if the first location is at an alert location relative to the support object.
1 . A system for monitoring an individual, comprising:
a processor;
a LIDAR sensor in electronic communication with the processor; and
wherein the processor is configured to:
receive a set of spatial data from the LIDAR sensor;
calculate a first location of the individual relative to a support object based on the set of spatial data; and
determine if the first location is at an alert location relative to the support object.
2 . The system of claim 1 , wherein the processor is configured to calculate the first location of the individual relative to the support object by:
distinguishing spatial data of the individual from spatial data of the support object; and
calculating a center of mass of the individual based on the spatial data of the individual.
3 . The system of claim 1 , where the processor is configured to determine an alert position of the individual relative to the support object by calculating a location of at least one edge of the support object.
4 . The system of claim 3 , wherein the alert location is determined if the center of mass of the individual is beyond the edge of the support object.
5 . The system of claim 3 , wherein the alert location is determined if the center of mass of the individual is within a predetermined distance of the edge of the support object.
6 . The system of claim 1 , wherein the processor is configured to send an alert signal when the first location is determined to be at the alert location.
7 . The system of claim 1 , wherein the processor is configured to:
receive a second set of spatial data from the LIDAR sensor;
calculate a second location of the individual relative to the support object based on the second set of spatial data; and
determine if the second location is at an alert location relative to the support object.
8 . The system of claim 7 , wherein the processor is configured to:
determine if the change from the first location to the second location is indicative of movement to an alert location.
9 . The system of claim 8 , wherein the processor is configured to:
calculate a probability that the individual will move to an alert location based on the first location and the second location.
10 . The system of claim 7 , wherein the processor is configured to:
determine a direction of movement of the individual.
11 . The system of claim 7 , wherein the processor is configured to:
determine a velocity of the individual.
12 . The system of claim 7 , wherein the processor is configured to:
receive one or more additional sets of spatial data from the LIDAR sensor; and
determine an acceleration of the individual based on the first location, the second location, and additional locations based on the one or more additional sets of spatial data.
13 . The system of claim 7 , wherein the processor is configured to:
determine if the individual has moved from a recumbent position to a sitting position based on the first location and the second location.
14 . A method for monitoring an individual, comprising:
receiving a first set of spatial data from a LIDAR sensor;
calculating a first location of the individual relative to a support object based on the first set of spatial data; and
determining if the first location is at an alert location relative to the support object.
15 . The method of claim 14 , wherein calculating a first location of the individual relative to the support object further comprises:
distinguishing spatial data of the individual from spatial data of the support object; and
calculating a center of mass of the individual based on the spatial data of the individual.
16 . The method of claim 14 , where determining an alert location of the individual relative to the support object further comprises calculating a location of at least one edge of the support object.
17 . The method of claim 16 , wherein the alert location is determined if the center of mass of the individual is beyond the edge of the support object.
18 . The method of claim 16 , wherein the alert location is determined if the center of mass of the individual is within a predetermined distance of the edge of the support object.
19 . The method of claim 14 , further comprising sending an alert signal when the first location is determined to be at an alert location.
20 . The method of claim 15 , further comprising:
receiving a second set of spatial data from the LIDAR sensor;
calculating a second location of the individual relative to the support object based on the second set of spatial data; and
determining if the second location is at an alert location relative to the support object.
21 . The method of claim 20 , further comprising determining if the change from the first location to the second location is indicative of movement to an alert location.
22 . The method of claim 21 , further comprising calculating a probability that the individual will move to an alert location based on the first location and the second location.
23 . The method of claim 20 , further comprising determining a direction of movement of the individual.
24 . The method of claim 20 , further comprising determining a velocity of the individual.
25 . The method of claim 20 , further comprising:
receiving one or more additional sets of spatial data from the LIDAR sensor; and
determining an acceleration of the individual based on the first location, the second location, and additional locations based on the one or more additional sets of spatial data.
26 . The method of claim 20 , further comprising:
determining if the individual has moved from a recumbent position to a sitting position based on the first location and the second location.
