Abstract
A method, subsea device, and system, of which the method includes acquiring data using one or more sensors of the subsea device, the data representing a subsea environment, compressing the data using one or more processors of the subsea device, transmitting the data wirelessly from the subsea device to the surface device, and decompressing the data using the surface device.
Claims14
A method for transmitting data from a subsea device to a surface device, comprising:
- acquiring data using one or more sensors of the subsea device, wherein the data represents a subsea environment;
- compressing the data using one or more processors of the subsea device, wherein compressing the data comprises partitioning the data into a low-resolution representation and one or more enhancement layers that are higher in resolution than the low-resolution representation;
- transmitting the low-resolution representation wirelessly from the subsea device to the surface device, wherein the surface device is configured to:
- receive and decompress the low-resolution representation, and
- view a first set of images represented by the low-resolution representation;
- and
- after transmitting the low-resolution representation, transmitting the one or more enhancement layers in sequence of increasing resolution, wherein the surface device is further configured to:
- receive and decompress the one or more enhancement layers;
- and
- view a second set of images represented by the one or more enhancement layers and the low-resolution representation after receiving and decompressing the one or more enhancement layers.
