METHOD AND SYSTEM FOR EVALUTING SIGNAGE
First Claim
1. A method for evaluating signage from a vehicle traveling on a road, the method comprising the steps of:
- capturing, by at least one camera in the vehicle, imagery of signage;
recording, by a processor, video data of the imagery of signage into a memory, the processor being arranged to control the camera, the video data being formed by image frames;
tagging, by the processor, each image frame of the image frames or a group of the image frames with time data, location data where the imagery of signage is captured, speed data taken from a vehicle information bus connection, and driving direction data of the vehicle;
identifying, by the processor, a specific signage in the image frame;
counting, by the processor, a least a potential number of people or a potential number of vehicles around the specific signage in the image frame;
measuring, by the processor, a viewing angle formed between a driving direction of the vehicle and a viewing direction to the specific signage from the camera;
classifying, by the processor, the specific signage into a signage group; and
forming, by the processor, one or more databases including the classified signage groups.

Abstract
A method for capturing a scene image of signage from a vehicle moving on a road or from a person'"'"'s perspective not in a vehicle, the method includes the steps of capturing scene images of signage, recording video data of the scene image of signage into a memory, the video data being formed by image frames, tagging each image frame of the image frames or a group of the image frames with time data and location data, identifying a specific signage in the image frame, counting a least a potential number of people and a potential number of vehicles around the specific signage in the image frame, measuring a viewing angle formed between a driving direction of the vehicle or between a direction of movement of a person not in a vehicle and a viewing direction to the specific signage from the camera, classifying the specific signage into one of signage groups, and forming one or more databases including the classified signage groups and impact of each signage object.

11. A method for evaluating signage from a vehicle traveling on a road, the method comprising the steps of:
-
capturing, by at least one camera in the vehicle, imagery of signage; recording, by a processor, video data of the imagery of signage into a memory, the processor being arranged to control the camera, the video data being formed by image frames; transmitting, by the processor, the video data to a server via network for analysis of signage; tagging, by the processor, each image frame of the image frames or a group of the image frames with time data, location data where the imagery of signage is captured, speed data and driving direction data of the vehicle; identifying, by the server, a specific signage in the image frame; counting, by the server, a least a potential number of people or a potential number of vehicles around the specific signage in the image frame; measuring, by the server, a viewing angle formed between a driving direction of the vehicle and a viewing direction to the specific signage from the camera; classifying, by the server, the specific signage into one of signage groups; and forming, by the server, one or more databases including the classified signage groups. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A method for evaluating signage from the perspective of a person not in a vehicle moving around the signage, the method comprising the steps of:
-
capturing, by at least one camera, imagery of signage; recording, by a processor, video data of the imagery of signage into a memory, the processor being arranged to control the camera, the video data being formed by image frames; tagging, by the processor, each image frame of the image frames or a group of the image frames with time data, location data where the imagery of signage is captured, and moving speed data calculated by using a combination of an cancellation obtained from a accelerometer and the location data; identifying, by the processor, a specific signage in the image frame; counting, by the processor, a least a potential number of people around the specific signage in the image frame; measuring, by the processor, a viewing angle formed between a moving direction of the people and a viewing direction to the specific signage from the camera; classifying, by the processor, the specific signage into a signage group; and forming, by the processor, one or more databases including the classified signage groups.
