Abstract

In an approach to spatial positioning using image parameters, a computer processor identifies one or more image parameters for an image subject. The processor identifies a first image of the image subject and determines whether the first image meets the one or more image parameters for the image subject. If the first image does not meet the one or more image parameters for the image subject, the processor calculates positional instructions based on the one or more image parameters for the image subject and the identified first image, where the calculated positional instructions include positioning instructions for one or more imaging devices.

Claims

1. A method for spatial positioning using image parameters, the method comprising:

identifying one or more image parameters for an image subject;

identifying a first image of the image subject taken by one or more imaging devices of an unmanned imaging vehicle;

responsive to determining that the first image does not meet one or more image parameters for the image subject based, at least in part, on three-dimensional positioning data of an imaging device of the one or more imaging devices of the unmanned imaging vehicle and an angle of the imaging device to the image subject;

calculating a new position for the unmanned imaging vehicle based, at least in part, on a position of an obstruction that blocks, at least in part, the image subject, wherein the new position enables the one or more imaging devices of the unmanned imaging vehicle to capture a second image utilizing, at least in part, the identified one or more image parameters;

calculating one or more positional adjustment instructions for the unmanned imaging vehicle based on the one or more image parameters for the image subject and the calculated new position for the unmanned imaging vehicle; and

sending the one or more positional adjustment instructions to the unmanned imaging vehicle;

identifying the second image of the image subject;

responsive to determining that the second image does not meet the one or more image parameters based, at least in part, on contrast in the second image, determining an amount of ambient light based, at least in part, on data received from one or more lighting sensors of the unmanned imaging vehicle;

determining that the one or more image parameters are not achievable based at least in part, on the contrast in the second image and the amount of ambient light, and in response, adjusting an image parameter representing an adjusted ISO value based, at least in part, on the amount of ambient light;

sending the image parameter representing the adjusted ISO value to the one or more imaging devices of the unmanned imaging vehicle;

receiving a third image taken utilizing the adjusted ISO value; and

determining that the third image meets the one or more image parameters, and in response, capturing a video of the image subject.
