Prior Art
Today, plate measurement is performed by means of capacitive sensor that is already provided within the laser head or laser sensor that can be attached to the head if it is desired to be more precise.
In said system in the state of art, the sensor performs reading by means of three points, one of which is at the left edge compared to the operator and two of which are at the lower edge, and said points are transferred to CNC system and thus, the positions of said points are used in geometric calculations. As a result of the calculations made by making use of said points, the starting point and rotation angle of the plate are determined. Said system in the state of art has drawbacks, limitations and disadvantages. Said drawbacks, limitations and disadvantages are as follows: the length and width of the plate cannot be measured, the dimension of the plate must be more than 500x500mm, the plate must be placed at a certain area or the operator must carry the head to the area where the measurement will be performed, the plate that will be measured must be in the shape of a rectangle, it is necessary that the plate must be free of any holes, which remain from the previous cuttings, the measurement process takes a long time, only a single plate can be measured at one time, and several small plates cannot be measured at the same time.
An application numbered TR2005/05027 has been found in the patent research relating the prior art. The technical content of said utility model is a control device for thickness and double-layered metal plate and is related to the use for supervision and control in pressing machines, shears, welding machines, printing, and lacquer and coating machines. A circuit board with all the necessary connections made, is placed at the bottom (lower) section of the plastic box obtained in a ready-made form and the upper cover and bottom (lower) section are interconnected by means of the lugs at the edges. Coil that is obtained by wrapping the copper wire having a thickness of 0.06 micron and fixed to the socket though the end sections, is placed in the interior section of the measurement sensor obtained by being processed from 303 stainless mill. The connection between the sensor and the device is achieved by means of a cable attached to the end of the socket.
As a result, improvements are made in the automatic plate measurement system and thus, new embodiments that will eliminate the abovementioned disadvantages and provide solutions for the present systems.

In this detailed description, the preferred embodiments of the plate measurement system (100) according to the present invention are described only for the subject to be understood better without any limiting effects.
Figure 1 is a perspective view of the plate measurement system (100) according to the present invention. The present invention enables measuring the width, length, cutting starting point and rotation angle of the metal plate to be cut on the cutting palette by means of an automatic plate measurement system (100) that is placed into the machine and has a camera system (101 ). The present invention comprises a laser head (103) that provides focusing of laser light for laser cutting. A laser sensor (104) that is positioned next to the laser head (103) and enables the plates to be detected, is provided. The operator controls the machine functions and visual plate measurement system by means of an operator panel (105). The plates are detected via a camera system (101 ). Reference points (102) that provide calibration values used for performing perspective adjustment process over the images achieved by means of said camera system (101 ), is provided. Automatic detection button (106) that enables the system, which is connected to the camera system (101 ) over said operator panel (105), to function automatically is provided. The first manual button (107) that activates zero- angle rectangle selection mode and second manual button (108) that activates the mode enabling the selection in angles different from zero by means of four points, are provided on the same operator panel (105). Always-on-top button (109) that enables the camera system (101 ) software to be seen always on top of the other screens, and machine monitoring button (1 10) that zooms the image in the plate measurement system (100) and enables thereof to be monitored on the screen and on the internet, are provided. Figure 2 is a two-dimensional top view of the plate measurement system (100) according to the present invention. A perspective image of the working area is obtained firstly by means of camera system (101 ) placed into the machine. A bird's eye image of the working area is obtained by means of calibration value achieved through the reference points (102) on the image obtained. Several filters and artificial intelligence software are applied on said image, the plates are detected from the cutting table exactly in a visual manner and the contours of the plates are displayed with green contour lines on the screen of the operator panel (105) for the operator to select easily the plate on which the operator will work. Thus, the operator can see the working area on the machine and the plates surrounded with green lines on the area instantly without experiencing time loss. Then what is left for the operator to do is that, in case the operator pressed the automatic detection button (106), according to the plate on which the laser cutting process will be operated, the operator presses and selects the contour determining the plate on the touchscreen on the operator panel (105). Thus, all the measurement required for cutting are made and unless any motion or human movement are detected in the machine and if the drawing that will be cut fits into said plate, the cutting process can be started on the related plate immediately.
Apart from automatic detection button (106), two manual modes that can be selected by the operator on the screen are provided. The first one of said modes is selected by pressing the first manual button (107) and the operator determines the cutting area that will be used, by drawing a rectangle on the plate. The second manual mode is selected by pressing the second manual button (108). In said mode, the operator creates a free rectangle on the plate by means of four points and the entire plate or a part of the plate can be selected as a cutting area. The second mode is especially used for measuring the plates that are inclined on the palette or performing cutting on the available part of the plates that have been cut previously, and on any parts of the plate where the drawing to be cut fits thereto.
