Abstract
When monitoring a workspace to determine whether scheduled tasks or chores are completed according to a predetermined schedule, a video monitoring system monitors a region of interest (ROI) to identify employee-generated signals representing completion of a scheduled task. An employee makes a mark or gesture in the ROI monitored by the video monitoring system and the system analyzes pixels in each captured frame of the ROI to identify an employee signal, map the signal to a corresponding scheduled task, update the task as having been completed upon receipt of the employee signal, and alert a manager of the facility as to whether the task has been completed or not.
Claims18
A method for verifying task completion via a video system, comprising:
- monitoring via one or more video cameras a region of interest (ROI);
- determining whether an employee signal has been detected in the region of interest by analyzing pixels in the ROI in video frames captured by the one or more video cameras;
- wherein analyzing the pixels in the ROI comprises, via a processor:
- segmenting each video frame into regions;
- and
- extracting feature vectors from each segmented region to identify the employee signal;
- upon determining that the employee signal has been detected, classifying the identified employee signal;
- and
- performing a table lookup to identify a task corresponding to the classified employee signal;
- updating a task schedule for the identified task to indicate completion of the task;
- and
- generating and transmitting a task completion alert message indicative of completion of the identified task;
- and
- upon determining that the employee signal has not been detected within a predetermined upper time limit for completing the task as determined by a timer, generating and transmitting an incomplete task alert message, wherein the transmission of the incomplete task alert message is treated as a detected employee signal and causes the timer to be reset.
A video system that facilitates verifying task completion in a retail or service environment, comprising:
- one or more video cameras that monitor a region of interest (ROI);
- a processor configured to:
- determine whether an employee signal has been detected in the region of interest by analyzing pixels in the ROI in video frames captured by the one or more video cameras;
- wherein analyzing the pixels in the ROI comprises, via a processor:
- segmenting each video frame into regions;
- and
- extracting feature vectors from each segmented region to identify the employee signal;
- upon determining that the employee signal has been detected, classifying the identified employee signal;
- and
- performing a table lookup to:
- identify a task corresponding to the detected employee signal;
- update a task schedule for the identified task to indicate completion of the task;
- generate and transmit a task completion alert message indicative of completion of the identified task;
- upon determining that the employee signal has not been detected within a predetermined upper time limit for completing the task as determined by a timer, generate and transmit an incomplete task alert message wherein the transmission of the incomplete task alert message is treated as a detected employee signal and causes the timer to be reset.
A method of verifying task completion in a retail or service environment, comprising:
- monitoring a scene with one or more video cameras;
- defining a region of interest (ROI) within the scene for detecting employee signal events;
- determining whether an employee signal has been detected in the region of interest by analyzing via a processor the ROI to detect employee signal events by segmenting each of a plurality of video frames into regions and extracting feature vectors from each segmented region to identify the employee signal;
- upon determining that the employee signal has been detected, classifying a detected signal event as corresponding to a completed task;
- updating a task completion schedule based on the classified signal event;
- generating and transmitting a task completion alert message indicative of the completed task;
- and
- upon determining that the employee signal has not been detected within a predetermined upper time limit for completing the task as determined by a timer, generating and transmitting an incomplete task alert message, wherein the transmission of the incomplete task alert message is treated as a detected employee signal and causes the timer to be reset.
