摘要： PURPOSE:To offer an accurate positioning method whose reliability is high by a method wherein the outside-shape contour of an image picked up by using a PV camera is extracted or the projection distribution of a component region is found and the approximate position of the image is then decided. CONSTITUTION:A silhouette image is taken into a memory at an image processing device when the image is input. Then, it is approximated to a polygon by executing a square approximation treatment. On the basis of image contour information obtained by the treatment, its recessed parts are filled; and an outside-shape contour is changed to a protruding figure. A rectangle which is overlapped best with the silhouette image of a component is selected. For example, in the case of the image of QFP, it is positioned by drawing measuring lines in parallel with individual sides of the rectangle and on the inner side by a prescribed amount which has been given in advance. In the case of a square ticket or the like, a positioning window is set on the inner side by a prescribed amount from corners of a circumscribed rectangle; then, its position and its angle can be decided by synthesizing all positions computed by using the window.

摘要： PURPOSE:To simplify the origination of dictionary data capable of corresponding to various characters by dividing a segmented character into meshes and analyzing character background structure in accordance with the ratio of the characters in the divided meshes. CONSTITUTION:A character is segmented and then a character frame is divided into several meshes less than 32 vertical and horizontal meshes and the meshes to be a background are noticed to analyze rough background structure. Since each mesh is expressed by one bit, a dictionary data can be expressed by the small number of bits corresponding to the number of divided meshes. At the time of forming dictionary data, the background structure of plural data is analyzed in each character (0-9, A-Z) based on real teaching, and every appearance of different background structure, new dictionary data are registered. Consequently, the system can be allowed to correspond to noises or changes of a character form (various character forms) and the dictionary origination based upon real teaching can be simplified.

摘要： PURPOSE:To realize a form recognition with high accuracy, by storing a parameter which regulates a straight line equation other than a pointer, or an end mark, at each line segment approximating data, and finding the apex of an approximate polygon as the intersection of a straight line. CONSTITUTION:Three picture element data adjacent to the present picture element position are read by an outline tracing program, and the progressing directions of the data are decided. A straight line template is referred corresponding to the progressing direction, and the pointer, and a new pointer, and straight line parameter corresponding to the direction, can be obtained. And a process is performed when the pointer is decided as the end mark by a straight line deciding program, by setting the present picture element position as a new start point, and the same process is repeated when the pointer is other than the end mark. In such way, the straight line parameter, and an end point coordinate are registered in order at a straight line string table. An intersection calculation program finds the intersection of a straight line based on those data, and the coordinate is registered at an apex string table, and the form recognition with high accuracy can be performed.

摘要： PURPOSE:To execute a decision quantitatively and also automatically by binary-coding an input image of a test pattern consisting of a repeated pattern which has been placed by the limit width of collapse, dividing an area and measuring the number of division, and deciding the cllapse. CONSTITUTION:With regard to a cut and collapse test pattern for evaluating the printing quality of a dot printer which has been placed on an illuminating light source 2, an image is inputted to an image processor 4 by a camera 1, and the cut or the collapse is decided by operating a CRT 5 and a keyboard 7, and starting an evaluating program stored by an FD driver 6. The test pattern 8 sets a width 10 between rectangles to the minimum width by which it is not allowed to cause a collapse, and its pattern is repeated. An image of the test pattern 8 is inputted, an area division of black and white of a binary-coded image is executed, a number is given in order and the number of black areas corresponding to an area of a printing pattern is calculated. In case when the number of measurement is smaller than a dictionary data, the pattern is decided to be a collapse pattern 11, and in case when both of them are the same, it is decided to be a normal pattern, and in case when the former is larger, it is decided that a pattern 12 becomes thin and divided into two or more areas, and has been counted.

摘要： PURPOSE:To measure a three-dimensional position with high accuracy irrelevantly to the distortion of a lens system by using a regular pattern and determining the correspondence relation between the position of an optional point in an object space determined by a TV camera and the position on its picked-up image. CONSTITUTION:A calibration plate PLT on which the regular pattern is drawn is placed on a Z0 axis so that it can shift in position, and its pattern edge is detected to project an X0Y0 coordinate system on an image coordinate system. Consequently, the spatial coordinate values of one point on the pattern corresponding to one point A on the image are calculated. Then the pattern is picked up by the TV camera every time the calibration plate PLT is placed at a different position on the Z0 axis, and then the object spatial coordinate values of each calibration plate position corresponding to specific picture elements are calculated. This three-dimensional position measuring method is employed to obtain a sight line equation.
