Embodiment Construction

[0085] The automatic detection method and device for wheel hub casting defects based on image understanding of the present invention are realized by combining software and hardware, and can detect both surface defects and internal defects. The software part is written in Fortran or C language on a general-purpose computer.

[0086] The method and system of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted here that the shapes and sizes in the drawings are only used for clearer explanation, rather than for expressing strict proportional relationship.

[0087] Fig. 1 is the overall work flowchart of the device of the present invention. There is an emergency stop button in the device. If you need an emergency stop after the power is turned on, you can press the emergency stop button to cut off the power supply. The normal working process is as follows:

[0088] (1) Turn on the power and start the device.

Abstract

The invention discloses an automatic detecting method and device of wheel hub casting defect based on image comprehension. It uses PLC controlling system to control moving and rotating of wheel hub and moving of X light pipe precisely. Parameters of PLC controlling system are set by detecting software of wheel hub casting defect in PC. Utilize X light to shoot images of wheel hub on different positions which are also set by the detecting software. Detecting software adopts detecting algorithm to distinguish wheel hub casting defect automatically. Detecting method contains manual, semi-automatic or automatic detecting program for selecting. The system has high precision and good stability, which improves automatic level of wheel hub detecting and the objectivity of detecting standards greatly.

Description

technical field [0001] The invention relates to an automatic detection method for wheel hub casting defects based on image understanding, and also relates to an automatic detection device for wheel hub casting defects based on image understanding. Background technique [0002] Image understanding is a science that automatically extracts information from images. The basic techniques of this subject include image composition modeling, image building, and data visualization. Image understanding is an important step in developing artificial intelligence systems that make decisions based on interpretations of input images (“Image Understanding”, Computer Engineering, Vol. 29, No. 11, pp. 23-24, 71, July 2003) . [0003] The wheel hub is also called the rim, which is an important exercise part of motor vehicles such as automobiles and motorcycles. The driving process of the car will generate lateral and longitudinal loads, accompanied by driving torque, braking torque, etc., and...
