FIELD OF THE INVENTION
The present invention generally relates to an electronic range estimator and more particularly relates to implementing a system and method for accurately estimating the distance of a remote object with the usage of electronic instruments such as digital angular rate gyroscope sensor and a digital accelerometer sensor associated with a smart weapon scope device.
BACKGROUND OF THE INVENTION
The present invention relates, in general, to the field of range measuring equipment. More particularly, this invention relates to a digital image processing system that is capable, through a use of an inclinometer, to identify the orientation of the object in the 3D physical space.
In the current scenario, a laser range technology is commonly used to determine the distance of a remote object. However, the laser range technology is encountered with a number of limitations while determining the distance of the remote object. For example, the technology requires a laser to be reflected off the target object; therefore it cannot be used effectively to identify distances of the objects that have poor or non reflective surfaces. Further, the laser range finders are associated with distance limitations due to the impact of the laser emitter power, which is determined, based on the distance of the target object. Further, the laser range finders have a greater chance of missing the reference objects to be captured based on the distance of the reference object.
Hence, there is a need for a better system that guarantees accurate distance measurement unlike laser range finders, which have distance limitations that are associated with the power of a laser emitter. Further, the system must be configured to virtually override the distance limitation as long as the reference object is visible through its digital camera. Further, the system must be capable of overcoming the limitation of accurate measurement of distant targets, and to guarantee that the laser beam aims accurate measurement of distant targets without missing the target, potentially introducing a significant opportunity for erroneous distance measurements.
SUMMARY OF THE INVENTION
The present invention relates to an electronic range estimator that is used for accurately measuring the distance of a remote object. Further, the electronic range estimator implements a method wherein said method comprises of accepting the vertical size of the remote object, determining the orientation angle by considering the top edge of the remote object; determining the orientation angle by considering the bottom edge of the remote object; and measuring the distance of the remote object based on the vertical size of the remote object and the orientation angles measured by considering the top edge and the bottom edge of the remote object.
Further, the present invention supports a range estimation measurement system for accurately measuring the distance of a remote object, wherein the system comprises of a digital angular rate gyroscope sensor, a digital accelerometer sensor, and the system is configured to accept the vertical size of the remote object. Further, the system is configured to determine an orientation angle from the top edge of the remote object and the bottom edge of the remote object using the digital angular rate gyroscope sensor. Further, the system is configured to compute the distance of the remote object by considering the vertical size of the remote object along with the orientation angles measured for the remote object using the digital accelerometer sensor.

The following detailed description of the preferred embodiments presents a description of certain specific embodiments to assist in understanding the claims. However, the present invention is intended to cover alternatives, modifications and equivalents, which may be included within the spirit and scope of the invention as defined by the appended claims. Furthermore, in the following detailed description of the present invention, numerous specific details are set forth in order to provide a thorough understanding of the present invention.

Referring to FIGS. 1a, 1b, and 1c illustrate a working overview of the system 100 for accurately measuring the distance/range of a remote object from the smart weapon scope device. As depicted in FIG. 1a, the user is allowed to focus the remote object 102 through the scoping lens 101 and to select the top edge of the focused object 103. Based on the selection of the top edge of the focused object 103, the system 100 determines the orientation angle of the remote object through the use of the digital angular rate gyroscope sensor. Further, as depicted in FIG. 1b, the user is allowed to focus the remote object 102 through the scope's objective lens 101 and select the bottom edge of the focused object 103. Based on the selection of the bottom edge of the focused object 103, the system 100 automatically determines the orientation angle of the remote object through the use of the digital angular rate gyroscope sensor. In an embodiment, the system 100 allows the user to specify a known or approximate vertical height of the remote object. Further, as depicted in FIG. 1c, the system 100 accurately determines the distance range of the remote object 105 based on the orientation angles (the top edge and the bottom edge) measured for the remote object and the vertical height specified for the remote object.
Referring to FIG. 2 illustrates a flow-chart 200 that explains the working of the system100 for accurately measuring the distance/range of a remote object from the smart weapon scope device. Initially, at step 201, the user registers with the system 100 for accurately measuring the distance/range of the remote object from the smart weapon scope device. Further, at step 202, as the user successfully registers with the system 100, the system 100 allows the registered user to configure the profile in the smart weapon scope device with an approximate vertical size of the remote object. Further, at step 203, the system 100 is configured to allow the user to focus and capture the remote object within the scope lens of the smart weapon scope device. Further, at step 204, the system 100 is configured to determine the orientation angle of the remote object that is measured from the top edge of the focused remote object as the user selects the top edge of the focused object. Further, at step 205, the system 100 is configured to determine the orientation angle of the remote object that is measured from the bottom edge of the focused remote object as the user selects the bottom edge of the focused object. In an embodiment, the system 100 uses a digital angular rate gyroscope sensor to measure the orientation angles of the top edge and the bottom edge of the remote object. Further, at step 206, the system 100 is configured to compute the distance range of the remote object based on the vertical size of the remote object and the orientation angles measured for the remote object. In an embodiment, the system 100 uses a digital accelerometer sensor to compute the distance range of the remote object based on the vertical size and the orientation angles determined for the remote object.

The Scope module 302 is designed to focus the device on the remote object, wherein the device can focus on the top edge, the bottom edge, and/or the center of the remote object. The Profile Configuration module 303 is configured to set the profile parameters for using the smart weapon scope device while capturing the remote object. The profile parameters include information about the vertical size of the remote object that is known or considered to be an approximate value, along with other parameter details such as Environmental conditions, sensors used to measure the orientation angles, the system resolution used for capturing the remote object, the accessories associated with the smart weapon scope device, or the like. The Distance Computation module 304 is configured to compute the distance of the remote object that is focused through the smart weapon scope device, wherein the distance of the remote object is computed based on the vertical size of the object and the orientation angles measured from the top edge and the bottom edge of the remote object.
