Individual identification and tracking via combined video and lidar systems

A method for data continuity across multiple imaging modalities, the method comprising:

• generating a virtual plane disposed at a first distance from a first imaging modality and a second distance from a second imaging modality, wherein the virtual plane is within an imaging field of each of the first imaging modality and the second imaging modality;
• recording a video frame via the first imaging modality, the video frame comprising the virtual plane;
• detecting, at the first imaging modality, one or more objects in the video frame at a first timepoint when the one or more objects enters the virtual plane;
• assigning an identifier to each of the one or more objects;
• detecting, at the second imaging modality, one or more three-dimensional shapes at a second timepoint when the one or more three-dimensional shapes enters the virtual plane wherein the second timepoint is coincident with the first timepoint;
• for each of the one or more objects, determining a corresponding shape of the one or more three-dimensional shapes;
• assigning each identifier to the respective corresponding shape of the one or more three-dimensional shapes;
• and
• after assigning each identifier, recording a plurality of positional data via the second imaging modality for each of the one or more three-dimensional shapes;
• and
• associating the plurality of positional data for each of the one or more three-dimensional shapes with a corresponding object of the one or more objects.

A computer program product for data continuity across multiple imaging modalities, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to perform a method comprising:

• generating a virtual plane disposed at a first distance from a first imaging modality and a second distance from a second imaging modality, wherein the virtual plane is within an imaging field of each of the first imaging modality and the second imaging modality;
• recording a video frame via the first imaging modality, the video frame comprising the virtual plane;
• detecting, at the first imaging modality, one or more objects in the video frame at a first timepoint when the one or more objects enters the virtual plane;
• assigning an identifier to each of the one or more objects;
• detecting, at the second imaging modality, one or more three-dimensional shapes at a second timepoint when the one or more three-dimensional shapes enters the virtual plane wherein the second timepoint is coincident with the first time point;
• for each of the one or more objects, determining a corresponding shape of the one or more three-dimensional shapes;
• assigning each identifier to the respective corresponding shape of the one or more three-dimensional shapes;
• and
• after assigning each identifier, recording a plurality of positional data via the second imaging modality for each of the one or more three-dimensional shapes;
• and
• associating the plurality of positional data for each of the one or more three-dimensional shapes with a corresponding object of the one or more objects.
