Embodiment Construction

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0031] Such as figure 1 The photographing principle of the prior art aerial photography acquisition method shown is that multiple cameras 3 are used for photographing, the body is heavy, the image utilization rate is low, and the cost is high.

[0032] Such as Figure 2 to Figure 7 A single-camera splicing image data acquisition method of the present invention includes the following steps:

[0033] Step (1): Set a preset path 1 for image acquis...

Abstract

The invention discloses a single-camera spliced image data acquisition method, which comprises the following steps: (1) setting a preset path for image acquisition, and setting a plurality of groups of pre-acquired image groups on the preset path; (2) carrying a camera on the aircraft to fly around the preset path and sequentially acquiring a plurality of groups of images, where the acquisition angle of the camera is controlled by a programmable stability augmentation holder with a position function, and the holder is reset before entering the preset path; (3) when the aircraft arrives at an initial preset shooting position, shooting one or more images in sequence, and recording the position and angle information of each image to obtain an image group; and (4) resetting the camera, and enabling the aircraft to shoot the next image group along the preset path until the shooting of the remaining preset shooting positions is completed. According to the acquisition method, a movement continuous shooting program can be matched through accurate angle exposure of the track programmable high-speed pan-tilt, and efficient and accurate acquisition of images is realized.

Description

technical field [0001] The invention relates to the field of aerial photography, in particular to a single-camera splicing image data collection method. Background technique [0002] With the rise of aerial photography, panoramic photography and real scene modeling, more and more images are collected, and the amount of data is also increasing. Many image acquisition methods have exceeded the performance of existing cores, and various A multi-core image acquisition method and device. [0003] According to the carrier classification, it is divided into air and ground equipment. According to the collection method and the object of use, it can be divided into multi-point collection and single-point collection. Multi-point acquisition requires high uniformity and is often used in engineering projects and measurements. Single-point collection has low requirements, and can be easily used by individuals, and is often used for entertainment and viewing. [0004] Aerial imaging eq...
