Size measurement scoring device, adjusting method and scoring method

Abstract

The invention discloses a size measurement scoring device, an adjusting method and a scoring method. The size measurement scoring device comprises a fixing frame, an operation table, a detection table, a light source and a camera. The detection table, the light source and the camera are arranged on the fixing frame; a through hole is formed in the middle of the detection table, and an object carrying plate is arranged at the through hole and is made of a transparent material; the light source is arranged below the detection table and is arranged corresponding to the carrying plate; the camerais arranged on the camera fixing plate right above the carrying plate; the operation table is electrically connected with the light source and the camera; a standard optical flat is arranged between the camera and the detection table; a telecentric coaxial lens is arranged at a lens of the camera, and a He-Ne laser is arranged on the side surface of the telecentric coaxial lens; a standard opticalflat is arranged between a camera and an object carrying plate, fine adjustment knobs are arranged at four corners of the object carrying plate, and a He-Ne laser is arranged on the camera, so that alens of the camera and the object carrying plate are arranged in parallel.

Description

technical field [0001] The invention relates to the field of image recognition, in particular to a size measuring and scoring device, an adjustment method and a scoring method. Background technique [0002] At present, domestic colleges and universities set up mechanical processing training courses for some specific majors, in which students are generally assessed during or at the end of the training, and there is a widely used assessment item that requires students to It is required to design and produce machined parts. By measuring the dimensions and specifications of the machined parts, they are compared with standard parts or requirements according to the accuracy value, tolerance and other indicators, and then the students' works are scored. At present, traditional measuring tools such as vernier calipers and micrometers are still used in colleges and universities for manual inspection to obtain the size specifications of machined parts. [0003] The traditional measur...

Problems solved by technology

[0003] The traditional measurement tools have the following disadvantages: 1. The positioning of the measurement object takes time; 2. The more measurement parts of a single measurement object, the longer the time-consuming; 3. Long-term measurement will cause eye fatigue and other problems to the measurement personnel. 4. The measurement position is judged by the surveyor, so the measurement results will vary from person to person; 5. There are also human errors in the measurement readings; 6. The measurement data needs to be manually entered and counted by the surveyor, which is time-consuming, inefficient, and easy. go wrong
