Deep learning is performed by using a material of a processing object, a laser beam parameter showing a property of laser beam which the processing object is irradiated with, and pre-processed part data and post-processed part data that respectively reflect laser processing-involved three-dimensional shapes of a processed part before and after irradiation of the processing object with the laser beam. A first relationship of input data that are the material of the processing object, the pre-processed part data, and the laser beam parameter to output data that is the post-processed part data after irradiation with the laser beam in relation to the input data is accordingly obtained as one learning result.

The present technology relates to a medical system, a signal processing device, and a signal processing method capable of obtaining highly accurate three-dimensional (3D) information in real time. Further, first 3D information regarding an operative field is generated with a first algorithm by using an operative field image obtained by imaging the operative field. In a case where an area of interest is set in the operative field image, second 3D information regarding the area of interest is generated with a second algorithm different from the first algorithm.

Medical system, signal processing device, and signal processing method

The present technology relates to a medical observation system, a method, and a medical observation device, which are capable of maintaining accuracy of three-dimensional information, even in a case where a change occurs in an optical system. A medical observation system acquires operative field data acquired by a medical observation device, detects a change in an optical system of the medical observation device, estimates a parameter representing a state of the optical system after a change occurs in the optical system in a case where the change in the optical system is detected, and sets a generation condition of three-dimensional information based on the operative field data by using an estimation result. The present technology can be applied to a surgery assisting system.
