Abstract
In an inspection method and apparatus, when an infrared (IR) image is obtained by using an IR camera and thermal image data corresponding to the obtained IR image is stored or inspected, confidence of the thermal image data is improved.
Claims14
A method of inspecting cap sealing of a container transferred along a process line by using an infrared (IR) camera, the method comprising:
- measuring a temperature by using a temperature sensor located within a field of view (FOV) of the IR camera;
- calculating a surface temperature of the temperature sensor based on thermal image data of the temperature sensor photographed by the IR camera;
- comparing a difference value between a first value measured by the temperature sensor and a second value that is calculated, with a certain threshold value;
- and
- correcting the thermal image data corresponding to the cap sealing of the container obtained by the IR camera based on the measured first value.

An apparatus for inspecting cap sealing of a container transferred along a process line by using an infrared (IR) camera, the apparatus comprising:
- the IR camera photographing the cap sealing of the container;
- a temperature sensor located within a field of view (FOV) of the IR camera and measuring a temperature;
- and
- a controller calculating a surface temperature of the temperature sensor based on thermal image data of the temperature sensor photographed by the IR camera, comparing a difference value between a first value measured by the temperature sensor and a second value that is calculated, with a certain threshold value, and correcting the thermal image data corresponding to the cap sealing of the container obtained by the IR camera based on the measured first value.
