Abstract
A welding information providing device is proposed. The device may include a body provided to cover at least a portion of a worker' face and including a first region facing the worker' face and a second region located in a region opposite to the first region. The device may also include a camera unit located in the second region of the body and capturing a welding video to acquire a video frame. The device may further include a display unit located in the first region of the body and providing a video generated through the video frame.
Claims11
A camera system comprising:
- an imaging portion including a camera configured to capture a welding image to acquire a video frame, wherein the camera comprises a front surface configured to receive light emitted from a welding light source, the front surface defining an optical receiving plane of the camera, and wherein a first virtual straight line is defined to be perpendicular to the front surface of the camera;
- and
- a light blocking portion located between the camera and the welding light source and including a light blocking cartridge structure configured to control welding light introduced into the imaging portion, wherein the light blocking cartridge structure comprises a first surface facing the front surface of the camera and a second surface opposing the first surface, and wherein a second virtual straight line is defined to be perpendicular to the second surface of the light blocking cartridge structure,
- the light blocking cartridge structure configured such that the first and second surfaces of the light blocking cartridge structure are tilted relative to the front surface of the camera so that the first virtual straight line and the second virtual straight line intersect each other.

A welding information providing device comprising:
- a body provided to cover at least a portion of a worker' face and including a first region facing the worker' face and a second region located in a region opposite to the first region;
- an outer cover unit located in the second region of the body;
- a camera unit located in the second region of the body and configured to capture a welding video to acquire a video frame, wherein the camera unit includes:
- a first camera configured to capture a scene other than welding to acquire a first video frame, and
- a second camera configured to capture a welding video to acquire a second video frame,
- wherein the second camera comprises a front surface configured to receive light emitted from a welding light source, the front surface defining an optical receiving plane of the second camera, and wherein a first virtual straight line is defined to be perpendicular to the front surface of the second camera;
- the outer cover unit further including an outer cover frame and a light blocking cartridge structure located between the outer cover frame and the second camera, wherein the light blocking cartridge structure comprises:
- a first surface facing the front surface of the second camera, and
- a second surface opposing the first surface and facing the outer cover frame, wherein a second virtual straight line is defined to be perpendicular to the second surface of the light blocking cartridge structure;
- and
- a display unit located in the first region of the body and configured to provide a video generated through the video frame,
- the light blocking cartridge structure configured such that the first and second surfaces of the light blocking cartridge structure are tilted relative to the front surface of the camera so that the first virtual straight line and the second virtual straight line intersect each other.
