Method for measuring object

Abstract

The invention relates to a method for measuring an object. The method comprises the following steps of: positioning the object, namely arranging the object on a rotating module; searching the optimal measurement position, namely driving the object to rotate by using the rotating module, and acquiring the optimal measurement position of the object by using an image acquisition device; acquiring an image of the object, namely acquiring the image of the object by using the image acquisition device when the object is positioned at the optimal measurement position; and measuring, namely measuring the acquired image of the object. In the method, the objected is driven to rotate by the rotating module to find the optimal measurement position of the object; and the method for measuring the image of the object at the optimal measurement position is quick and is accurate in sizes, and the problem of low consistency during manual operation can be solved.

Description

technical field [0001] The present invention relates to a measuring method, in particular to a measuring method suitable for measuring the dimensions of objects such as screws, nuts, gaskets, sleeves, rods, valves and the like. Background technique [0002] Generally, when the image measuring machines, projectors or other measuring tools sold in the market are in use, they usually need to be measured manually through complicated settings and operating procedures. Therefore, when the number of items to be measured increases, the operating time of the staff will be increased. In addition, if there are multiple identical objects to be measured, the operator must repeatedly set and perform various operations, causing operational troubles , and all measurement actions and settings are manually operated, so not only the quality is not easy to be consistent during measurement, but also the measurement process cannot be recorded. [0003] On the other hand, the measuring tools used...

Problems solved by technology

[0002] Generally, when using image measuring machines, projectors, or other measuring tools sold on the market, it usually requires manual and complicated settings and operating procedures to perform measurements

Therefore, when the number of items to be measured increases, the operating time of the staff will be increased. In addition, if there are multiple identical objects to be measured, the operator must repeatedly set and perform various operations, causing operational troubles , and all measurement actions and settings are manually operated, so not only the quality is not easy to be consistent during measurement, but also the measurement process cannot be recorded

[0003] On the other hand, the measuring tools used to measure objects such as screws etc. on the market are all fixed and then measured. This fixed measuring tool can only measure the size range that the imaging device can Objects within the pickup range, that is to say, when the overall length of the object is greater than the pickup range of the imaging device, various measurement operations cannot be performed

In addition, if the opposite sides and corners of the screw heads of objects such as screws are non-circularly symmetrical, this fixed object measuring device cannot measure the relevant dimensions. Therefore, the conventional fixed measuring tools and methods The scope of use is subject to many restrictions

[0004] It can be seen that the above-mentioned existing object measurement method obviously still has inconvenience and defects in method and use, and needs to be further improved urgently.

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and the general method has no suitable method to solve the above-mentioned problems. This is obviously related. The problem that the industry is eager to solve
