摘要： PROBLEM TO BE SOLVED: To quickly restore a high resolution three-dimensional image in a wide range. SOLUTION: Two line image pickup devices are disposed so that their optical axes can be prevented from being made in parallel with each other, and that the line direction can be prevented from being made in parallel with the moving direction, and those line image pickup devices are configured to photograph the line images of the same scenery while moving. Two longitudinal images are prepared by compounding the line images in the time axial direction so that the photographic interval distances of the line images can be fixed based on the photographic place information, and the same objects on the two longitudinal images are made correspond, and a distance and height from the moving path to the object to be imaged is calculated based on the deviation in the time axial direction of the image pickup positions of the corresponding same objects, the fixed interval distances, and the line direction and optical axial direction. The similarity of the local region of the first longitudinal image and the local region of the second longitudinal image is calculated, and the distance and height to the object to be imaged is calculated based on the similarity and the shape model.

摘要： PROBLEM TO BE SOLVED: To recognize a specific pattern or a vehicle from image data photographed at a constant moving distance interval when an observation side and an object to be recognized are relatively moved. SOLUTION: An observation side at which a line sensor camera is set and an object including a specific pattern to be recognized are relatively moved in parallel, and when the object is photographed at a constant relative moving distance interval, the specific pattern is recognized from the time-sequential image data. In this case, the template of the specific pattern which is previously recorded in the line axial direction of the line sensor camera is enlarged and reduced, and the template is compared with the image data so that the similarity of the pattern can be calculated, and the specific pattern can be recognized from the image data by using the similarity of the pattern.

摘要： PROBLEM TO BE SOLVED: To identify a person on the basis of different eyegrounds image data, or retrieve desired storage data using an index, by sorting eyegrounds, images according to an objective criterion on the basis of data resulting from the processing and analysis of the eyegrounds images. SOLUTION: An eyegrounds image is entered at a step S102 and binary coded. A vascular image is extracted at a step S103 and formed into fine lines, thereby finding vascular branch and intersection points at a step S104. A Voronoi diagram is prepared using the branch and intersection points as mother points at a step S105, and the area of Boronoi polygons surrounding each mother point of the Voronoi diagram is calculated at a step S106. Then, images are sorted on the basis of the calculated area and the number of the polygons at a step 107, and data is stored at a step S108.

摘要： PROBLEM TO BE SOLVED: To accurately obtain depth information such as unevenness of a building, even when an obstacle such as a human being and a parked vehicle exists in measurement of a distance, or even when a photographing vehicle meanders in the measurement. SOLUTION: A measuring part 1-S is mounted on the vehicle or the like, a moving distance from a start point of the measurement is measured, while moving, to be accumulated as the moving distance in an accumulation part 1-L. A distance along a direction perpendicular to a moving direction is measured while making synchronize with the moving distance to be accumulated as a perpendicular-directional depth information in an accumulation part 1-D. A perpendicular-directional image photographed by the same manner is accumulated in an accumulation part 1-G. An image correlating processing 1-3 conducts the accumulation of the moving distance, the perpendicular-directional depth information and the image twice or more while conforming the start points thereof, and the same body within the perpendicular- directional image is correlated in every combination by twice times out of the accumulated perpendicular-directional images. A depth information estimating part 1-4 estimates the depth information collectively based on the perpendicular-directional depth information accumulated twice or more and an image correlation result correlated hereinbefore.

摘要： PROBLEM TO BE SOLVED: To detect a high-speed mobile object without being restricted by the object and illumination change. SOLUTION: The high-speed mobile object crossing over a line axis is photographed at fixed period interval to obtain a line image (301), an average luminance value is calculated which comprises the line images for the portion of preceding a plurality of periods (307) and the line image is adjusted in convergence and gain (309) when the average luminance value is out of a regulated range (308). An image change amount between each line image and a line image obtained one period before is calculated (302) so as to detect an image change point where the image change amount becomes equal to or more than a threshold and, then, the high-speed mobile object is detected (303).
