Description

Tool system, tool, work object recognition system, work object recognition method, and program Technical Field The present invention relates generally to a tool system, a tool, a work object identification system, a work object identification method, and a program. More particularly, the present invention relates to a tool system for use in a portable tool, a work object identification system, a work object identification method, and a program. Background Patent document 1 discloses a tool system including a portable tool having an image pickup unit and a drive unit activated by power supplied from a battery pack. The camera unit is arranged to e.g. encompass within its camera range a socket attached to the output shaft of the tool. The image pickup unit picks up an image of an object of work (which may be, for example, an object or a place where work is performed using a tool) during work using the tool. According to patent document 1, an object to which a tool is set in a proper position (i.e., an object arranged to make the tool ready to start working on the object) is identified using an image captured by an imaging unit. The tool system compares a photographed image generated by the image capturing unit with a plurality of reference images stored in the image storage unit, and thereby identifies a work object photographed in the photographed image. If the tool system of patent document 1 attempts to identify a work object photographed in a photographed image during the period in which the photographing unit is operating, power consumption increases. Prior art literature Patent literature Patent document 1 Japanese patent application laid-open No. 2019-042860 Disclosure of Invention In view of the foregoing background, it is therefore an object of the present invention to provide a tool system, a tool, a work object recognition system, a work object recognition method, and a program, all of which are configured or designed to reduce power consumption.
