Construction machine
A construction machine acquires efficiently and accurately the target surface to be displayed or controlled. The construction machine includes: a design surface information storage unit storing three-dimensional target shape as multiple design surfaces; a work equipment velocity vector acquisition unit detecting or estimating the velocity of work equipment; a work equipment position acquisition unit detecting or estimating the position of the work equipment; a target surface acquisition unit acquiring a principal target surface to acquire an estimated target surface that is potentially the next principal target surface; an operation control unit correcting the work equipment velocity; and a display unit displaying the positional relations between the work equipment position and the principal target surface. The target surface acquisition unit includes an estimated target surface calculation unit determining as an estimated target surface the design surface located in the direction of the work equipment velocity vector.
