Method, device and system for determining operation accuracy of watch hand

Abstract

The invention discloses a method, device and system for determining the operation accuracy of a watch hand. The method comprises the steps as follows: controlling the watch hand to rotate for preset time at a preset constant speed from a position corresponding to test starting time; acquiring a first dial plate image collected by a camera at a position where the rotation of the watch hand is finished; identifying the watch hand and a marking position in the first dial plate image according to a watch hand template and a marking position template, and determining the positions of the watch hand and the marking position in the first dial plate image; calculating a first clockwise angle from the position of the watch hand to the marking position; calculating a first difference value of the first clockwise angle and a standard clockwise angle; judging whether the first difference value is greater than a preset error threshold; if so, judging that the operation of the watch hand is not accurate. Therefore, by the scheme, the operation accuracy of the watch hand can be accurately determined, the unqualified watches can be timely detected, and prevented from entering the market, and the ex factory pass rate of the watches is improved.

Description

technical field [0001] The invention relates to the technical field of watches, in particular to a method, device and system for judging the accuracy of watch hands. Background technique [0002] With the development of the watch industry, more and more types of watches are emerging in the market. There are traditional mechanical watches and emerging smart watches. Mechanical watches use mechanical movements to drive the hands to rotate. They are mainly divided into automatic mechanical movements and through The mechanical movement with the clockwork on the knob. The advantage of this kind of watch is that it does not need to be charged. It can be worn for many years and is unique. The watch movement is all made of mechanical parts. Its accuracy reflects the level of mechanical technology, but its function is relatively simple. , can only display the time; there is also a battery-powered watch, for example, the emerging smart watch, with a variety of sensors to achieve more ...
