Abstract

A system for the enhancement of sonar data is provided comprising one or more processors, a memory, and one or more sonar transducer assemblies configured to provide sonar data. The memory includes computer program code configured to, when executed, cause the processor(s) to receive the sonar data, with the sonar data providing information representative of an underwater environment around a watercraft. The computer program code is also configured to, when executed, cause the processor(s) to perform adaptive contrast image processing to adjust a brightness level or color of the sonar data at one or more locations and to form adjusted sonar data. Adaptive contrast image processing considers a distance of a location from a sonar transducer assembly of the one or more sonar transducer assemblies, a brightness level, color, water clarity, or depth associated with a location, an object type, or an orientation or surface properties of the object.
