Multi-lens oblique photogrammetric camera

Abstract

The invention discloses a multi-lens oblique photogrammetric camera which comprises a support, photographing modules, a switching module, a processing module, a synchronous exposure module, a display port, a primary function module and a storage module, wherein the photographing modules are used for collecting photographing data, the switching module is used for integrating the photographing data collected by the photographing modules, the processing module is used for processing the integrated photographing data and forming image data, the synchronous exposure module is used for generating uniform line field signals and controlling the photographing modules to expose synchronously, the display port is used for transmitting the image data, the primary function module is used for inserting data information for the image data, and the storage module is used for storing the image data where the data information is inserted. According to the multi-lens oblique photogrammetric camera disclosed by the invention, exposure consistency and location synchronism of all the photographing modules are guaranteed; data storage is concentrated, data is convenient to gather, and data compilation is simpler in lateral production processing; meanwhile, the multi-lens oblique photogrammetric camera disclosed by the invention has simpler combination process and wide application range.

Description

technical field [0001] The invention relates to the field of aerial photogrammetry, in particular to a multi-lens tilt photogrammetry camera. Background technique [0002] Multi-lens oblique photogrammetry subverts the limitation that orthophotos can only be taken from vertical angles in the past. By carrying multiple sensors on the same flight platform, images are collected from five different angles including one vertical and four obliques at the same time. A real and intuitive world that conforms to human vision is introduced. [0003] In the prior art, a multi-lens tilt photogrammetry camera is assembled with a single-lens camera or a mobile phone to capture ground objects from multiple angles. This method has the following disadvantages: 1. It is difficult to realize the exposure consistency and positioning synchronization of the shooting units at various angles; 2. It is difficult to use the combination of finished cameras in the market, which is limited by volume, we...

Problems solved by technology

This method has the following disadvantages: 1. It is difficult to realize the exposure consistency and positioning synchronization of the shooting units at various angles; 2. It is difficult to use the combination of finished cameras in the market, which is limited by volume, weight, Shape, etc., are often too large in size and weight, and are limited to large-scale drones; 3. The data storage is relatively scattered, and each shooting unit can only use its own original storage structure (basically a memory card, the storage read and write speed slow, limited capacity), the storage media are distributed in each camera, the data aggregation is cumbersome, and the data sorting is very difficult in post-production processing
