The embodiment of the invention discloses an oblique photography pod image data encryption method and device. The method comprises the steps: reading a section of byte data from the unprocessed imagedata and registering the data in an input registration space after image data in an image data input module is confirmed not to be completely processed, judging the data attribute of one byte in the input registration space, and if the data attribute is a flag bit, judging whether the data content of the next byte is a type code of the flag or not, if the data content is the type code of the flag,registering the data in an output registration space, otherwise, running an encryption algorithm to encrypt the two bytes, if the data attribute is the image content, running an encryption algorithmto encrypt the image content, storing the encrypted data in the output registration space, and judging whether the byte data in the input registration space are completely processed or not, if the byte data are completely processed, judging whether the image data are completely processed or not, and otherwise, continuing to process the unencrypted data in the input registration space.
Description
[0001] This specification relates to the field of unmanned aerial vehicles, in particular, it relates to a method and device for encrypting image data of an inclined photography cabin. Background technique [0002] In the field of aerial surveying, when measuring the target scene, the tilted photography cabin carried by the UAV is generally used to obliquely photograph the target scene to obtain image data; and then use the obtained image data to carry out 3D image modeling of the target scene , to achieve the measurement of the target scene. The inclined photography cabin is a camera system composed of one or more cameras. During the flight of the UAV, some abnormal conditions such as mechanical failure, insufficient power, being shot down, etc. occur from time to time, which will cause the UAV to lose contact and be difficult to retrieve. At this time, the collected image data, because it is not encrypted, is often leaked or viewed by irrelevant personnel. In some applicat...
