Abstract:
1. A method for identifying an asset, the method comprising: illuminating an identification pattern for the asset with non-visible light, wherein the identification pattern comprises retroreflective material encoding identity information of the asset; adjusting a shutter speed of an image sensor and a power of the non-visible light based on a motion state of the asset, wherein the motion state of the asset causes oscillating movement of the identification pattern, wherein the image sensor is configured to receive a response of the retroreflective material to the incident non-visible light; selecting at least a portion of the response for processing based on a determination of a probable location of the identification pattern on the asset, wherein the probable location of the identification pattern is detected based on the oscillating movement of the identification pattern; and identifying the asset based on decoded identity information, wherein the decoded identity information is obtained by processing the selected portion of the response of the retroreflective material.
