Method and apparatus for verifying an object image in a captured optical image

A device for providing dynamic feedback for verifying image capture of an optical image that includes a candidate license plate, the device comprising:

• an image analyzer configured to analyze a plurality of frames of a captured video to determine whether each frame includes an object image with a candidate text string for the candidate license plate;
• a text string scoring determiner configured to score each candidate text string identified in each respective object image by assigning a respective object image score for each object image based on relative positions of each alphanumeric character therein;
• a device operation instructor configured to dynamically determine a highest score of the assigned object image scores assigned for the object images of a plurality of the captured frames and to generate an operation adjustment control if the determined highest score is less than a predetermined score threshold;
• a dynamic instruction generator configured to generate at least one visual instruction based on the operation adjustment control;
• a display configured to dynamically display the generated at least one visual instruction during the continuous capture of the video, with the generated at least one visual instruction configured to provide a user instruction for adjusting video capture;
• and
• an object image verifier configured to verify that at least one frame of the plurality of frames, which is captured after the adjusting of the video capture based on the generated at least one visual instruction, includes a verified license plate number when the assigned object image score for the at least one frame is greater than the predetermined score threshold.

A method for providing dynamic feedback for verifying image capture of an optical image that includes a candidate license plate, the method comprising:

• analyzing, by a processor, a plurality of frames of a captured video to determine whether each frame includes an object image with a candidate text string for the candidate license plate;
• scoring, by the processor, each candidate text string identified in each respective object image by assigning a respective object image score for each object image based on relative positions of each alphanumeric character therein;
• dynamically determining, by the processor, a highest score of the assigned object image scores assigned for the object images of a plurality of the captured frames;
• generating, by the processor, an operation adjustment control if the determined highest score is less than a predetermined score threshold;
• generating, by the processor, at least one visual instruction based on the operation adjustment control;
• dynamically displaying, by a display screen controlled by the processor, the generated at least one visual instruction during the continuous capture of the video, with the generated at least one visual instruction configured to provide a user instruction for adjusting video capture;
• and
• verifying, by the processor, that at least one frame of the plurality of frames, which is captured after the adjusting of the video capture based on the generated at least one visual instruction, includes a verified license plate number when the assigned object image score for the at least one frame is greater than the predetermined score threshold.
