A launch monitor that includes substantially all of its functional components on or within a housing is disclosed. The launch monitor may be transported and used in any desired location. One or more cameras, flashes, and triggers may be used to acquire images of a golf club and golf ball. The launch monitor is preferably capable of receiving and transmitting data over a wireless network. Acquired images and other data may be analyzed by a processor, and then displayed using an LED, LCD or other type of display or printer.

wherein the rate of automatically distinguishing between the first and second golf clubs is about six seconds or less, and wherein the stored image reference information comprises Eigen values for the plurality of golf clubs, and wherein the step of automatically distinguishing between the first and second golf clubs comprises calculating the Eigen value of the at least one golf club from the acquired image and comparing it to the stored image reference information.
2. The method according to claim 1 , wherein the rate of automatically distinguishing between the first and second golf clubs is about three seconds or less.
3. The method according to claim 1 , wherein the rate of automatically distinguishing between the first and second golf clubs is about one second or less.
4. The method according to claim 1 , further comprising providing an imaging system having a resolution of greater than about 0.5 lp/mm.
5. The method according to claim 4 , wherein the imaging system has a resolution of greater than about 1 lp/mm.
6. The method according to claim 4 , wherein the imaging system has a resolution of greater than about 5 lp/mm.
7. The method according to claim 1 , wherein said stored image reference information is based on at least one of a logo, an indicia printed on the surface of the golf club, or a geometric profile of the club.
8. The method of claim 1 , wherein the at least one golf club has a marker applied to an outer surface.
9. The method of claim 8 , wherein the outer surface of the at least one golf club comprises at least 3 markers.
10. The method of claim 9 , wherein the markers are operable to create a high contrast with the surface of the at least one golf club.
11. The method of claim 1 , wherein the stored image reference information comprises information for about 50 or more golf clubs.
12. A system for identifying a golf object, comprising:
at least one camera system; and
a computational device operable to distinguish between two golf objects of the same type based on a comparison of an image acquired by the camera system and a library of stored reference information, wherein the stored image reference information comprises Eigen values for the plurality of golf objects;
wherein the computational device is operable to automatically identify the two golf objects of the same type, based on a calculation of the Eigen value of the golf objects from the acquired image and a comparison to the stored image reference information, in about six seconds or less.
13. The system according to claim 12 , wherein the computational device is operable to identify the acquired image in about three seconds or less.
14. The system according to claim 12 , wherein the computational device is operable to identify the acquired image in about one second or less.

16. The system according to claim 15 , wherein the resolution comprises greater than about 1 lp/mm.
17. The system according to claim 15 , wherein the resolution comprises greater than about 5 lp/mm.
18. The system according to claim 12 , wherein the stored reference information is based on features of said golf objects comprising a logo, an indicia printed on the surface of the golf object, or a geometric profile of the golf object.
19. A method for identifying a golf ball, comprising:
performing the following steps using a processor and a memory;
storing image reference information for a plurality of golf balls, wherein the stored image reference information comprises Eigen values for the plurality of golf balls;
acquiring an image of at least one of the golf balls in motion; and
automatically distinguishing at least one golf ball from the plurality of golf balls based on a comparison of the acquired image and the stored image reference information, and wherein the step of automatically distinguishing the at least one golf ball comprises calculating the Eigen value of the at least one golf ball from the acquired image and comparing it to the stored image reference information;
wherein the rate of automatically identifying the at least one golf ball is about six seconds or less.
20. The method according to claim 19 , wherein the stored image reference information is based on features of the golf ball comprising one or more of a logo, an indicia printed on the surface of the golf ball, or a geometric profile of the golf ball.
21. The method of claim 19 , further comprising:
storing image reference information for a plurality of golf clubs;
acquiring an image of at least one of the golf clubs in motion; and
automatically distinguishing between a first golf club and a second golf club based on a comparison of the acquired image and the stored image reference information;
wherein the rate of automatically identifying the at least one golf club is about six seconds or less.
