Resolution detection device

A resolution detection device applied to a camera device, the resolution detection device comprising:

• at least one arc-shaped structural member, position of the at least one arc-shaped structural member reaching a predefined distance relative to a detection point;
• and
• an identification member formed on the at least one arc-shaped structural member and comprising a plurality of identification patterns, a plurality of intervals respectively between the plurality of identification patterns and the detection point being equal to the predefined distance;
• wherein the camera device acquires a captured image through the detection point, and the captured image contains at least parts of the plurality of identification patterns;
• wherein the camera device is assembly comprising a relay lens disposed on the detection point and a camera lens disposed adjacent to the relay lens, or the camera lens disposed on a long range detection point;
• wherein an arc length formed by a distribution range of the plurality of identification patterns on the arc-shaped structural member is a computation value of the predefined distance and a maximal field of view of the relay lens.
