摘要： PURPOSE:To detect the shape defect of an object regardless of the size by generating the geometrical contour model of an object as a reference pattern, and comparing it with an object image to detect the shape defect. CONSTITUTION:The surface of an object to be inspected 201 is photographed with a camera 202, and the obtained image signal is sent to an image processing section 203. The image processing section 203 generates a contour model approximating an object image from the image signal with straight lines and circular arcs, compares the contour model with the original object image, detects the defect of the inspected object 201 and the shape defect of the excess portion, and displays the result on an output monitor 204. The analogous change of the shape of the same object can be coped with, and the defect and the shape defect of the excess portion can be detected regardless of the size.

摘要： PURPOSE:To extract the angle of an object surface with a high precision independently of the variance of reflection distribution of the surface by illuminating the object with an illumination system consisting of many various color parts and analyzing the color reflected from the surface. CONSTITUTION:For example, a circle line illumination 2 and a semispherical multicolor food 3 where concentric circles are divided by color are used to illuminate the object with the illumination system consisting of many various color parts. A specular surface object like chip parts 5 having a solder part 6 modulated on a printed board 4 is put in the hood 3 and its image is picked up from above by a color TV camera 1 or the like. Then, the color reflected from the surface of the specular surface object is identified, and angles (for example, theta1 and theta2) of the object surface to a horizontal plane are determined by this color. Since the angle is determined correspondingly to each picture element of reflection, angles of almost all minute faces of the specular surface object are determined with one image picking-up without adopting a special lighting method. A form is restored from points, whose height is known, based on these angles to extract the form of the specular surface object.

摘要： PURPOSE:To make it possible to ensure the detection of the presence or absence of a polarization mark within a window by setting the window at a position where the polarization mark should be present in data, and processing the two-dimensional image data within the window. CONSTITUTION:A window is used for two-dimensional image data in order to detect polarization marks. The window is set as a relative positional relationship based on an actual mounting position. Namely, the window is not set as a relative positional relationship based on the designed mounting position data for each polar part. In general, the actual mounting position of the polar part is obtained based on the two-dimensional image data of the characteristic parts of the entire polar part or a part thereof. When the window is set for the two-dimensional image data based on the actual mounting position of the polar part, the window is properly set at a position where the polarization mark should be located. The presence or absence of the polarization mark is detected by processing the two-dimensional image data within the properly set window. Thus, the inspection of the polarity of the polar part can be performed.

摘要： PURPOSE:To obtain the accurate position of a part and the direction of rotation by obtaining the straight line which crosses a row from the gravity center of the image of each contact in a contact row. CONSTITUTION:A rectangle 20 shows the contact image of the four sides of a part. First, the gravity center position X mark of the rectangle 20 is obtained, and the center line (straight line) 21 of a lead row which connected the gravity centers by a specific operation method is obtained. Next, the change point (X mark) of brightness on the line 21 is obtained. This point corresponds to the boundary of a contact image. The midpoint (O mark) of two change points catching the image 20 is obtained and it is made the position of its contact. After the position of each contact of the row is determined, the average position (double-circle mark) of the contact of the row is made the center position c of the row, and similarly the center positions a, b, and d of each row is operated, and from the intersection O (center coordinate of parts) of the straight lines ac and bd and the bisector D of the two straight lines, the accurate position of the part and the direction of rotation are obtained.

摘要： PURPOSE:To decide objective characters with high accuracy by adding together the binary images of display objects of the same type after setting them in the same size for production of a gradation image. CONSTITUTION:The size a unified among the binary images 1-3 of characters C1-Cn of the same type having blurs, etc., due to the difference of size, shape and print density. Thus a gradation image 4 of a character C is obtained. In the same way, the gradation images 5, 6 and 7 are obtained for characters O, D and G which are similar to the character C. Then the part of each of those gradation images that has the maximum density (a) is set at a fixed value 255 together with addition of (255-a) to the density of other parts for level-up. Thus the images 4-7 can be compared with each other at the same level. Then the difference images (e)=C-O, (f)=C-D and (g)=C-G are produced for the gradation characters having the increased levels. These images (e), (f) and (g) are added together for acquisition of an image (h). This image (h) is defined as an image of a character C feature dictionary which is used to separate the character C from other similar characters.

摘要： PURPOSE:To obtain the titled apparatus capable of confirming and inspecting a three-dimensional object in a real time in a production line, by confirming the entire shape of the three-dimensional object from the unevenness relation of the object obtained by projecting a pattern to the object and the surface relation of the object preliminarily given without directly extracting all of the surfaces of the object. CONSTITUTION:The indication of a shape, for example, the indication of a rectangular parallelopiped is sent to a surface relation processing apparatus 8 from a console 4. The surface relation of each shape is stored in a block 42 and the information of the property of the rectangular parallelopiped of the block 43 is referred to by indication. Light is projected to an object 9 to be measured by a TV camera 1 and two projectors 2 obliquely mounted to said camera 1 and the part impinged against the surface of the object 9 of the pattern thereof is extracted by an unevenness position detector 7. From the extracted part, the coordinates of the apex calculated in an image processor 3 are inputted to the apparatus 8. Then, the number of apices are checked and a deficient apex is calculated. By this method, high speed three-dimensional confirmation can be confirmed without requiring the confirmation of all surfaces.
