Abstract

<P>PROBLEM TO BE SOLVED: To stably analyze the state of a liquid in a container by image processing. <P>SOLUTION: Since a color difference with the liquid in the container becomes clear by changing the color or material of the opposite surface or part of the container, it is possible to perform a stable analysis by an image processor. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention can analyze the state of a liquid by image processing by using a special container or a chip in automatic dispensing or manual dispensing of a liquid currently performed in a hospital or a laboratory. It is designed to be performed stably. In addition, the present invention can be used not only by itself but also by being assembled into an existing analyzer or production apparatus.

  As a means of analyzing the state of the liquid contained in a container or a chip, there is one that measures ultrasonic waves, static electricity, and pressure, but measurement by image processing can be analyzed in detail from the color and saturation of the liquid. Because it can, it can be said to be the most effective means.

  Conventionally, when analyzing the state of a liquid in a container or a chip, a colored liquid could be easily analyzed by an image processing apparatus. The liquid was difficult to identify because it was difficult to identify.

  By changing the color or material of the container or chip on the other side or at an arbitrary location, the color difference of the liquid contained therein becomes clear and can be stably analyzed by the image processing apparatus.

  In this way, the state of the liquid can be constantly monitored when the liquid dispensing operation is performed automatically or manually, and troubles can occur in the event of liquid leakage or excessive or insufficient liquid volume. It can be prevented in advance.

BEST MODE FOR CARRYING OUT THE INVENTION

  The present invention makes it easy to stably analyze the state of the liquid contained in a container or a chip. If this is described with reference to the drawings, the chip 1 is only partially coated from a sharp tip to an arbitrary height. The painted surface 2 is made. Similarly, a part of the bottle 3 is painted in an arbitrary range of its height, and a painted surface 4 is formed. The liquid level of the chip 1 is clearly projected by the illumination 5, and it is photographed by the camera 6 and analyzed by the image processing device 7. As shown in FIG. 4, the tip 1 is provided with the coating surface 2 so that the liquid level in the tip is filled with liquid when viewed from the front opposite to the surface to be coated. The color difference where it does not enter is clear and the liquid level 8 can be easily identified. In addition, when air bubbles are mixed in or water droplets are attached, it can be similarly identified.

  In addition, this invention is not limited to the said one Embodiment, A various deformation | transformation is possible in the range which does not change the summary of invention.

  For example, in the above-described embodiment, a container or a chip that changes a part of the color is used. However, the color may be changed to a different color not only at one place but also at a plurality of places.

  Furthermore, in the above-described embodiment, a container or chip in which a part of the color is changed is used, but a container in which the material is changed instead of the color may be used.

  Since the present invention can be incorporated into various devices, the application range is wide. For example, it can be used for checking the amount of liquid in an analyzer or a production line, and can contribute to improvement in yield.

      It is the front view and side view of a chip | tip.       It is the front view and side view of a bottle.       It is a system configuration of the apparatus.       It is the front view and side view of a chip | tip and a liquid level.
