Description

Područje na koje se izum odnosi The field to which the invention relates

Izum se koristi u TV i filmskoj industriji, a odnosi se na elektroničku opremu, univerzalni dodatak za potpornu strukturu kamere, poznatiju kao kran za kameru. Izum je uređaj koji služi za automatsko usmjeravanje kamere prilikom snimanja. The invention is used in the TV and film industry and relates to electronic equipment, a universal accessory for a camera support structure, commonly known as a camera crane. The invention is a device that serves to automatically direct the camera during recording.

Tehnički problem Technical problem

Izum se koristi kao dodatak za potpornu strukturu kamere (kran za kameru) (Slike 1,2 i 3).Potporna struktura kamere koristi se prilikom snimanja za mijenjanje pozicije kamere u prostoru (npr. Simuliranje leta iznad dječjeg igrališta), prilikom njenog pomicanja, često je potrebno kameru usmjeravati (zakretati) prema nekom objektu u prostoru(slike 1 i 2).Potporna struktura ili kran nosač za kameru funkcionira tako da ruku krana operater-snimatelj pomiče u prostoru kako bi željeni objekt snimao iz raznih pozicija.Prilikom pomicanja ruke krana pomiče se i pozicija kamere, pa je potrebno uvijek iznova podesiti kut kamere prema željenom objektu snimanja. Rotacija kamere najčešće se kontrolira pomoću upravljačke palice i elektromotora. Budući da je za takvo usmjeravanje kamere potrebno vrlo precizno kontrolirati upravljačku palicu, nerijetko dolazi do grešaka i ponavljanja snimanja dok se ne dođe do zadovoljavajućeg rezultata. Prilikom prijenosa uživo, često se pojavljuju greške koje je nemoguće predvidjeti, a ovise o trenutnoj spretnosti operatera tj. kamermana. The invention is used as an accessory for the camera support structure (camera crane) (Figures 1, 2 and 3). it is often necessary to direct (rotate) the camera towards an object in space (pictures 1 and 2). The support structure or crane support for the camera functions so that the operator-recorder moves the arm of the crane in space in order to record the desired object from various positions. When moving the arm the crane moves and the position of the camera, so it is necessary to adjust the angle of the camera again and again according to the desired recording object. The rotation of the camera is most often controlled using a joystick and an electric motor. Since for such camera direction it is necessary to control the control stick very precisely, there are often mistakes and repetitions of recording until a satisfactory result is reached. When broadcasting live, errors often occur that are impossible to predict, and depend on the current dexterity of the operator, i.e. the cameraman.

Izum pomaže na način da prilikom snimanja objekta koji se ne pomiče u prostoru eliminira potrebu za ručnim upravljanjem upravljačkom palicom u cilju podešenja kamere na željeni objekt snimanja. Elektroničke komponente (Slika 5) ugrađene u kran sa kamerom očitavaju njegovu poziciju i određuju poziciju kamere, kako bi ista uvijek bila fokusirana na željeni objekt. Uporabom predmetnog izuma korisnik slobodno može pomicati kran i ruku krana, te prepustiti elektronici da kameru usmjerava prema objektu snimanja.Na taj način dobivamo preciznu snimku iz raznih položaja tj. kuteva kamere, a da je pritom sama kamera uvijek fokusirana na metu tj. željeni objekt. The invention helps in the way that when recording an object that does not move in space, it eliminates the need for manual control of the joystick in order to adjust the camera to the desired recording object. Electronic components (Figure 5) built into the camera crane read its position and determine the position of the camera, so that it is always focused on the desired object. By using the subject invention, the user can freely move the crane and the crane arm, and let the electronics direct the camera towards the recording object. In this way, we get a precise shot from various positions, i.e. camera angles, while the camera itself is always focused on the target, i.e. the desired object .

Stanje tehnike State of the art

Potporna struktura kamere, tzv. kran kamere (Slika 1,2 i 3) odavno je poznata naprava u industriji snimanja, vezanoj za film ili televiziju.Poznato je zaista bezbroj verzija ove naprave, ali svima je zajednički cilj mogućnost snimanja objekta u prostoru iz raznih pozicija tj. kuteva, kao i izmjene kadrova.Slika 2 prikazuje najčešće korištenu varijantu takve naprave i način njenog pomicanja.Potpornom strukturom za kameru upravlja čovjek, operater tj. kamerman, pa je potrebno mnogo znanja, iskustva, pa i talenta za upravljanje napravom na što precizniji način.Preciznost je potrebna kako bi se smanjilo vrijeme samog snimanja koje često stvara nepotrebne troškove zbog toga što često dolazi do pogreške operatera tj. snimatelja i ponavljanja kadrova.Poseban problem nepreciznosti kamermana očituje se kod prijenosa i snimanja uživo. U stanju tehnike poznata su različita tehnička rješenja kojima je cilj poboljšanje pokretljivosti kamere, kvalitete snimke ili olakšanja za operatera u smislu olakšanja pri korištenju kamere i opreme.Također poznate su različite varijante upravljačke palice, joysticka ili volana za upravljanje rotacijom kamere.No ovaj izum nudi inovativno rješenje u smislu potpore operateru ili kamermanu u cilju smanjenja pogrešaka., te omogućuje da elektronika upravlja kamerom umjesto operatera.Dakle izum u odnosu na stanje tehnike ostvaruje novost u smislu smanjenja pogrešaka prilikom snimanja uzrokovanih ljudskim faktorom. The supporting structure of the camera, the so-called The camera crane (Figure 1, 2 and 3) has long been a well-known device in the filming industry, related to film or television. There are indeed countless versions of this device, but the common goal of all of them is the possibility of recording an object in space from various positions, i.e. angles, such as and frame changes. Figure 2 shows the most commonly used variant of such a device and the way it is moved. The supporting structure for the camera is controlled by a human, the operator, i.e. the cameraman, so a lot of knowledge, experience, and even talent is needed to operate the device as precisely as possible. The precision is necessary in order to reduce the time of the recording itself, which often creates unnecessary costs due to the frequent errors of the operator, i.e. the cameraman, and the repetition of frames. A special problem of the inaccuracy of the cameraman manifests itself in live transmission and recording. Various technical solutions are known in the state of the art, the aim of which is to improve the mobility of the camera, the quality of the recording, or to make it easier for the operator to use the camera and equipment. Different variants of the control stick, joystick or steering wheel are also known for controlling the rotation of the camera. However, this invention offers an innovative solution in terms of supporting the operator or cameraman in order to reduce errors., and allows the electronics to control the camera instead of the operator. Thus, the invention achieves novelty in relation to the state of the art in terms of reducing errors during recording caused by the human factor.

Izlaganje suštine izuma Presentation of the essence of the invention

Primarni cilj izuma je osigurati preciznu kontrolu kamere prilikom njenog pomicanja , na način da kamera uvijek prati željeni objekt snimanja. Sekundarni cilj je smanjiti mogućnost ljudske pogreške, te pritom smanjiti vrijeme potrebno za snimanje, osigurati kvalitetu snimke prilikom prijenosa uživo. The primary goal of the invention is to ensure precise control of the camera during its movement, so that the camera always follows the desired recording object. The secondary goal is to reduce the possibility of human error, and at the same time to reduce the time required for recording, to ensure the quality of the recording during live transmission.

Na potpornu strukturu kamere poznatiju kao kran kamere ugrađuje se predmetni izum, koji se sastoji iz 5 senzora S1,S2,S3,S4 i S5 koji detektiraju poziciju krana i kamere u prostoru i 2 motora M1 i M2 koji služe za upravljanje, rotaciju kamere u željenom smjeru.Kada sustav sadržava pokretno postolje za kran, na isto se ugrađuje senzor S5 koji bilježi pomicanje sustava tj. kompletnog krana.Ugrađeni senzori i motori povezani su sa upravljačkom pločom sa računalom u kojem se nalazi software za detektiranje pozicije krana i kamere.Kada računalo očita stanje senzora, izračunava kut na koji je potrebno podesiti kameru kako bi željeni predmet ostao u meti snimanja.Računalo zatim pomoću ugrađenih motora okreće tj. usmjerava kameru prema željenom objektu. The invention in question is installed on the supporting structure of the camera, better known as the camera crane, which consists of 5 sensors S1, S2, S3, S4 and S5 that detect the position of the crane and the camera in space and 2 motors M1 and M2 that serve to control, rotate the camera in in the desired direction. When the system contains a mobile stand for the crane, the S5 sensor is installed on it, which records the movement of the system, i.e. the complete crane. The built-in sensors and motors are connected to the control panel with a computer that contains the software for detecting the position of the crane and the camera. the computer reads the state of the sensor, calculates the angle to which the camera needs to be adjusted so that the desired object remains in the recording target. The computer then uses the built-in motors to turn, i.e. direct the camera towards the desired object.

Dakle operater tj. snimatelj treba pomoću računala odabrati željeni objekt snimanja i memorirati ga u računalu.Zatim okreće ruku krana u proizvoljnom smjeru, npr. iznad ili ispod mete objekta (Slika 2), dok računalo upravljajući motorima M1 i M2 postavlja i okreće kameru prema memoriranom objektu. So, the operator, i.e. the videographer, must use the computer to select the desired recording object and memorize it in the computer. Then he turns the crane arm in an arbitrary direction, e.g. above or below the target object (Figure 2), while the computer, controlling the motors M1 and M2, positions and turns the camera towards to the memorized object.

Na taj način elektroničke naprave u obliku senzora i elektro motora ugrađene u potpornu strukturu kamere, pomoću računala i software-a automatski usmjeravaju kameru na memorirani objekt. In this way, electronic devices in the form of sensors and electric motors built into the supporting structure of the camera automatically direct the camera to the memorized object using a computer and software.

Tako je mogućnost pogreške operatera svedena na najmanju moguću mjeru, a kamera uvijek prati željeni objekt u prostoru. Thus, the possibility of operator error is minimized, and the camera always follows the desired object in space.

Na pokretno podnožje 8 ugrađujemo rotacijski senzor S5 koji bilježi pomicanje kompletne strukture u prostoru. At the junction of the crane arm with the crane stand, we install 2 rotary sensors S3 and S4 that determine and detect the angle at which the crane arm is located. On the movable base 8, we install the rotation sensor S5, which registers the movement of the complete structure in space.

Upravljačka ploča koja se sastoji od računala 4 sa pripadajućim software-om i palicom za upravljanje 5, povezuje se sa senzorima S1, S2, S3, S4 i S5, te elektromotorima M1 i M2.

c) Pomičemo ruku krana 2 u proizvoljnom smjeru, tako da kamera više ne bude usmjerena prema objektu snimanja c) We move the arm of crane 2 in an arbitrary direction, so that the camera is no longer directed towards the recording object

d) Upravljačkom palicom ponovno usmjerimo kameru prema željenom objektu snimanja d) Use the control stick to direct the camera again towards the desired recording object

e) Pritisnemo tipku „Pravac 2" e) Press the button "Direction 2"

f) Računalni softvvare računa na kojoj se poziciji nalazi objekt (kao presjecište dva pravca), te se uključuje automatsko usmjeravanje. f) The computer software calculates the position of the object (as the intersection of two directions), and automatic routing is activated.

g) Slobodno okrećemo ruku krana, a kamera se automatski usmjerava prema željenom objektu. g) We freely turn the arm of the crane, and the camera is automatically directed towards the desired object.

h) Ukoliko se objekt pomakne sa starog mjesta, kameru je potrebno upravljačkom palicom ponovno usmjeriti prema objektu, i automatsko usmjeravanje će nastaviti sa radom, međutim sada će se usmjeravati prema novoj 'pomaknutoj' točki. h) If the object moves from its old location, the camera needs to be re-directed towards the object with the joystick, and automatic guidance will continue to work, but now it will be directed towards the new 'moved' point.

i) Ukoliko želimo prekinuti automatsko usmjeravanje potrebno je pritisnuti tipku „Izlaz", i sustav se ponovno vraća u „ručni" način rada. i) If we want to stop automatic routing, it is necessary to press the "Exit" button, and the system returns to "manual" operating mode.
