1. An ultrasound diagnosis apparatus comprising: a data acquisition unit to acquire ultrasound data of a target object; and an image processor to: generate an ultrasound image by using the ultrasound data, acquire a standard view representing a plane of the target object including at least one of measurement objects used to diagnose the target object based on the ultrasound image, and information related to the standard view, the information comprising at least one among a type of the standard view, a location of the target object, and a direction of the target object, set a caliper to measure the target object on the standard view, based on a user input, acquire measurement information including caliper information of a position of the caliper and at least one point on the caliper, based on the standard view, and automatically acquire the at least one of the measurement objects being measured to diagnose the target object, based on the caliper information indicating that the caliper is inclined from a predetermined line on the standard view by a value that is within a first range, and that the at least one point on the caliper is away from a predetermined point in the standard view by a value that is within a second range, wherein the image processor is further configured to acquire the measurement objects by determining whether the caliper is inclined by a value that is within the first range, or the at least one point on the caliper is away from the predetermined point by a value that is within the second range.
