Description

  The present invention relates to a monitor device used for construction machines such as a hydraulic excavator, and in particular, includes a television camera provided rearward from the construction machine and a television camera provided laterally. Construction with a function to display two images obtained by the two television cameras arranged side by side as a single image on a monitor device provided at a position where the images can be viewed from the driver's seat The present invention relates to a machine monitoring device.

  Conventionally, in construction machines such as hydraulic excavators, in particular, construction machines with a complex structure in which an upper swing body is pivotably mounted on a lower traveling body, not only the front side but also the side and rear are monitored. It is necessary to ensure safety in all directions.

  Therefore, in response to a request to monitor not only the front side of the construction machine but also the side and the rear side, technical development of a construction machine monitoring device has been made (for example, see Patent Document 1). The invention described in Patent Document 1 is provided with a recess on the rear surface of a member mounted on the rear part of the construction machine, for example, a counterweight, in order to avoid damage to the main body of the imaging means for the monitor device such as a TV camera, The main body of the imaging means such as a TV camera is disposed in the recess.

  In addition, in construction machines such as hydraulic excavators, it is important to ensure the safety of people and animals moving in the rear area of the construction machine, and the monitoring device for the construction machine is used for the driver of the construction machine. It is also very important to be easy to use. In particular, a television camera or the like is provided from the construction machine to the side and / or rearward, and the image itself obtained by the imaging device for the monitor device such as the television camera, that is, the normal image is directed to the driver's seat. When the image is viewed from an imaging means such as a TV camera (the rear direction from the construction machine) In the right and left direction (moving direction of the imaging target) of the visible image. For this reason, the left-right direction of movement of the imaging target drawn on the display device is opposite to the actual direction of movement, which may cause misidentification. Therefore, an image (mirror image) formed by reversing the image itself (normal image) captured by the rear monitoring imaging means in the left-right direction and reversing the left-right direction for the purpose of eliminating this drawback is displayed in front of the driver's seat. There is also known a monitoring camera system for a construction machine that displays on a display device arranged (see, for example, Patent Document 2).

  Furthermore, it has a plurality of image pickup means, and a plurality of images acquired by using the plurality of image pickup means are combined into a single image, and the single image is used as a single display means. In the case of a monitoring apparatus that displays images, if there is a large difference in the distance between each of the plurality of imaging means and the subject, there is a disadvantage that the image is distorted at the boundary of the synthesized image. is there. Patent Document 3 is known as a technique for solving this drawback.

In the invention described in Patent Document 3, (a) the other imaging means (second imaging means) is arranged behind one imaging means (first imaging means), and (b) first imaging means and second imaging means. (C) A composite image created by placing a first image on one side and (d) placing a second image on the other side with reference to the boundary line. And (e) a correction processing means having a function of executing a step of correcting at least one of the obstacles existing on the boundary line and included in the two images and then aligning with the other obstacle. A monitoring device is disclosed.

  In addition to Patent Documents 1, 2, and 3 as conventional techniques, for example, imaging means 6 and 7 are provided at the rear and side of a construction machine main body such as a hydraulic excavator as shown in FIG. There is also known a construction machine monitoring device in which a display means 8 is disposed toward the driver's seat 3 diagonally forward of the driver's seat 3 provided in the vehicle.

  Then, as shown in FIG. 10, the display unit 8 has a rear image display unit 82 for displaying a mirror image of the imaging object 9 obtained by the rear imaging unit 6 in the left half, and the side imaging unit 7 takes an image. A side image display unit 81 for displaying a normal image of the imaged object 9 obtained in this way is juxtaposed on the right half to display one continuous image.

  The reason for using the mirror image of the imaging target 9 obtained by imaging by the rear imaging means 6 is the same as that taught in Patent Document 2. That is, an image (normal image) obtained by imaging by the rear imaging means 6 provided toward the rear is opposite to the direction viewed by the driver facing the front. For this reason, when the image obtained by imaging backward is displayed backward and observed toward the front, the disadvantage that the horizontal direction is reversed is avoided.

  By the way, for example, when the imaging object 9 moves in order from the left (A) point to the right (B) point and from the right (B) point to the previous (C) point as shown in FIG. The rear image display unit 82 moves from the left (A) point to the right (B) point, and then disappears from the monitor, and then appears on the side image display unit 81 from the right, from the (B) point to the (C) point. Move to the left. Accordingly, the movement of the image that moves through the rear image display unit 82 and the side image display unit 81 on one display means 8 is not continuous between the left and right (the rear image display unit 82 and the side image display unit 81). The driver cannot intuitively understand the movement of the image. For this reason, there is a possibility that it may be confused and cause an erroneous operation, and there is a serious problem from the viewpoint of maintaining safety.

  Therefore, the present invention should be solved in order to eliminate such disadvantages and to accurately monitor the movement of objects and people around the construction machine to eliminate erroneous operation of the construction machine and ensure safety.
