Embodiment Construction

[0036] Next, refer to Figure 1 to Figure 11 An embodiment of the periodic motion observation system of the present invention will be described.

[0037] [overall composition]

[0038] figure 1 It is a schematic diagram showing the mechanical constitution of the periodic motion observation system (hereinafter referred to as the system) of the present embodiment. figure 2 Then it is the block diagram of the circuit structure of this system.

[0039] This system is used to observe the rotation status of a DC motor that rotates at a high speed with a predetermined period as the observation object M. It has: an LED light source 1 that emits a flash at a predetermined period and illuminates the observation object; a light-emitting control device 2 for Controlling the light-emitting period and light-emitting time of the LED light source 1; the camera 3 photographs the observation object M that is irradiated by the LED light source 1; and the image analysis device 4 analyzes the...

Abstract

The purpose of the present invention is to provide a periodic motion observation system, made to a simple configuration, with which it is possible to specify with high accuracy the locus, speed, and a place in which strain, etc., has occurred in the periodic motion of an object to be observed. A flash light is emitted every prescribed period from a light source 1 and the periodic motion at a prescribed observation point of an object M to be observed is image-captured by an image-capturing camera 3, and then the image pertaining to the periodic motion at the prescribed observation point of the object M to be observed that was captured by the image-capturing camera 3 is analyzed by an image analysis device 4. This image analysis unit 4 extracts, on the basis of the image pertaining to the periodic motion at the prescribed observation point of the object M to be observed, the coordinates of the prescribed observation point at a time when the prescribed observation point of the object M to be observed is irradiated by the light source, and outputs each of the coordinates in tabular form or graphic form.

Description

technical field [0001] The present invention relates to a periodic motion observation system for observing the periodic motion of a predetermined observation point as an observation object by emitting a flash light from a light source and irradiating it on the observation object in periodic motion. Background technique [0002] When the light source emits a flash of light for an instant, and at the same time repeatedly emits the flash of light at a certain period, and illuminates the observation object in periodic motion, the observation object is in a static state or in a slow motion state of slow motion. The strobe effect has been used in various fields. Objects of observation include, for example, a motor that rotates at a high speed at a constant cycle, a printer that discharges liquid droplets at a constant cycle and travels at a predetermined speed, a fuel ejection device, and the like. [0003] However, a method using a so-called high-speed camera is known as a metho...
