Abstract
The utility model relates to a multi-lens structure of a wide format array digital camera, which is composed of four digital cameras mounted on a steadier to form a format array type photographing structure. The multi-lens structure is characterized in that the four lenses of the four digital cameras are mounted on the inwardly cambered surface of the circular concave disk type steadier, the included angle (Alpha) between the central line of each mounting hole of the steadier and the axial line of the circular concave disk type steadier is between 17 degrees and 20 degrees, the projective centers of the four lenses are positioned on the same plane to form an rectangle, the lengths of the two sides (a, b) of the rectangle are respectively between 259mm and 261mm and between 209mm and 211mm, and the included angle (Beta) between the central line of each lens and the diagonal line of the rectangle is between 63 degrees and 65 degrees. Compared with the prior device, the multi-lens structure has the advantage that the multi-lens structure utilizes the small images of the four lenses to generate a large virtual image, which can reach 11.5K multiplied by 8K after being sampled, equal to the format of the traditional film camera, so the multi-lens structure can satisfy the data-processing requirement of the prior photogrammetric survey workstation. Under the premise of meeting the requirement of aerial operation specifications, the base-height ratio of the lens arrangement method can reach 0.59, thus greatly increasing the vertical accuracy of aerial photogrammetric survey, which can reach one ten-thousandth of a flight relative height.
Description
Technical field
The utility model is a kind of many lens constructions of wide format battle array digital camera, belongs to the technical field of structures of product.
Background technology
The digital aerial camera of the wide film size face of many camera lenses battle array is to produce under traditional film camera and external digital aerial camera occupy the main flow background of aeroplane photography camera, and, operation weather very long at traditional film camera data cost costliness, flow chart of data processing requires shortcoming such as harsh, that data precision is on the low side and external digital aerial camera costs an arm and a leg, vertical accuracy is low, can't carry out the production of mapping and 4D product.The digital aerial camera of the wide film size face of many camera lenses battle array compare with the digital aerial camera of external aviation have nearly square film size, technical advantages such as big field angle, big base-height ratio, have the complete integration mode of equipment such as self-powered, GPS.SWDC phase machine operation vertical accuracy be ten thousand of flying height/, be 2 times of traditional film camera vertical accuracy, the 4-5 of external digital aerial camera vertical accuracy doubly more than, can carry out the production of 4D product fully.Simultaneously, digital aerial camera working days is much higher than traditional film camera, and its horizontal visibility only requires (traditional camera requires more than 10 kilometers) more than 3 kilometers, and the high-level efficiency of digital aerial camera will impel it to replace traditional photogrammetric measurement camera fully.This number aerial camera is succeeded in developing the revolutionary character progress that may cause air photogrammetry section, the characteristics of high degree of overlapping, high vertical accuracy may make photogrammetric measurement to the replacement lidar measurement, and adopt aerophotogrammetric mode in engineering survey.The digital aerial camera data storage device of the wide film size face of many camera lenses battle array is reusable, and main application fields is departments such as territory, mapping, water conservancy, highway, railway, urban construction, environmental protection, tourism.
The digital aerial camera of the wide film size face of many camera lenses battle array is developed for the conventional film aerial camera that replaces the photogrammetric measurement field, and its operation result's high plane and vertical accuracy and high-level efficiency are expected to and the low cost of the digital aerial camera of the wide film size face of many camera lenses battle array is expected to thoroughly replace part close shot camera in conventional film aerial camera, external digital aerial camera, the close shot fields of measurement.Wide film size face battle array aviation digital camera relates to technical fields such as mapping, photogrammetric measurement, close shot measurement, engineering survey.
The lens construction of digital aerial camera commonly used mainly exists single-lens and many camera lenses dual mode at present, single-lens digital aerial camera breadth is little can not to satisfy aerophotogrammetric needs fully, and the most employing of existing multi-lens digital aerial camera is that specialty measures camera, cost an arm and a leg, inner degree of overlapping is low, vertical accuracy is low, can not satisfy the needs of making the 4D product.
Summary of the invention
The shortcoming that the utility model exists at above-mentioned prior art just and design many lens constructions that a kind of wide format battle array digital camera is provided, its objective is and adopt the digital camera of non-measurement to realize wide film size, high-precision digital photogrammetric measurement, reduce cost of products.
The purpose of this utility model realizes by following measure:
Many lens constructions of this kind wide format battle array digital camera, it is to be made of four rack-mount digital cameras, form planar array type and take structure, it is characterized in that: four camera lenses of four digital cameras are installed on the intrados of a recessed disc carrier of circle, angle α between the center line of its mounting hole and the axis of circular recessed disc carrier is 17～20 degree, the projection centre of four camera lenses is positioned on the same plane also rectangular, two length of side a and the b length of rectangle are respectively 259～261 millimeters, 209～211 millimeters, the angle β between the center line of camera lens and the diagonal line of rectangle is 63～65 degree.
Technical solutions of the utility model are for the field angle that solves digital aerial camera, the problem of base-height ratio, have adopted the outer field stitching technology of many camera lenses splicings, integrated four 2,200 ten thousand digital non-metric cameras of pixel.Its inner image overlap degree is at 10%-15%.The integrated requirement of satisfying the wide film size of photogrammetric measurement of many camera lenses, micreikonic inner Duplication guarantee the virtual image that carries out relevant treatment between snapshot of oneself picture and generate big film size.
