LA DOCUMENTACION CIENTIFICA, CONSERVACION Y PRESERVACION DEL PATRIMONIO CULTURAL REQUIERE DE SOLUCIONES TECNICAS EFECTIVAS QUE APORTEN INFORMACION PRECISA Y CONTRASTADA ACERCA DEL BIEN PATRIMONIAL. EN EL AMBITO ARQUEOLOGICO, LA INMENSIDAD DE LOS ABRIGOS O CUEVAS CON PINTURAS DE ARTE RUPESTRE PREHISTORICO ESTAN EXPUESTOS A MULTITUD DE CONDICIONANTES AMBIENTALES Y METEOROLOGICOS QUE DIFICULTAN SU PRESERVACION EN ENTORNOS OROGRAFICOS COMPLEJOS Y DISPERSOS EN EL ESPACIO. LAS LABORES DE DOCUMENTACION DE LOS ABRIGOS SON ARDUAS Y DELICADAS, NO SOLO POR LA DIFICULTAD DE LECTURA DEL PIGMENTO (FUERTEMENTE EROSIONADO Y DESGASTADO), SINO POR LA COMPLEJIDAD DEL SOPORTE, EL ELEVADO NUMERO DE MOTIVOS (SUPERPUESTOS O NO), Y LA FUERTE VARIACION LUMINICA QUE LOS AFECTA, DIFICULTANDO SU INTERPRETACION (A NO SER QUE EXISTE UNA BUENA BASE DOCUMENTAL PREVIA). SE HAN UTILIZADO A LO LARGO DEL TIEMPO DIFERENTES TECNICAS PARA DOCUMENTAR LOS ABRIGOS, PASANDO POR LA REALIZACION DE DIBUJOS, CALCOS, FOTOGRAFIAS, Y EVENTUALMENTE, CALCOS DIGITALES, TRATAMIENTO MULTIESPECTRAL, ASIO COMO LA GENERACION DE MODELOS 3D MEDIANTE LASER ESCANER Y/O FOTOGRAMETRIA. ESTE PROYECTO DA UN PASO MAS ALLA Y PROPONE UNA SOLUCION CIENTIFICA INEDITA Y DE VANGUARDIA._x000D_ ESTE PROYECTO PERSIGUE INTEGRAR EL ANALISIS ESPECTROFOTOMETRICO DE ENVEJECIMIENTO, LA COLORIMETRIA Y LA IMAGEN FOTOGRAFICA MULTIESPECTRAL CAPTURADA MEDIANTE CAMARA DIGITAL CALIBRADA (ESPACIAL Y ESPECTRALMENTE), EN UNA SOLA SOLUCION QUE PERMITA IDENTIFICAR Y MAPEAR AUTOMATICAMENTE LOS PIGMENTOS CON MAXIMA FIABILIDAD EN LEVANTAMIENTOS/MODELOS/RECONSTRUCCIONES TRIDIMENSIONALES (3D), O 4D (INCLUYENDO LA VARIABLE TIEMPO). LA INTEGRACION DE LAS CUATRO COMPONENTES ESPECTRAL, COLORIMETRICA, RADIOMETRICA Y ESPACIAL PASA POR UTILIZAR LA CARTA DE COLOR COMO REFERENCIA BASICA (PATRON), Y CONVERTIR LA CAMARA DIGITAL EN UN INSTRUMENTO DE PRECISION CAPAZ DE EXTRAPOLAR EL CONTENIDO RADIOMETRICO (POR BANDA DE CADA IMAGEN CAPTURADA) EN VALORES COLORIMETRICOS Y ESPECTRALES. DICHOS VALORES SE ANALIZARAN Y PROYECTARAN SOBRE LOS MODELOS 3D O 4D GENERADOS A PARTIR DE MULTIPLES IMAGENES CONVERGENTES O ESTEREOSCOPICAS. _x000D_ ADICIONALMENTE, SE PLANTEA LA MONITORIZACION DE LOS PIGMENTOS A LO LARGO DEL TIEMPO (MEDIANTE EL ANALISIS DE ENVEJECIMIENTO), CON LA CONSIGUIENTE EXTRAPOLACION AL CONJUNTO DE LOS ABRIGOS/CUEVAS, DE MANERA QUE PUEDA VISUALIZARSE Y PREDECIR SU COMPORTAMIENTO FUTURO (A LO LARGO DE VARIOS SIGLOS) SOBRE LAS PROPIAS IMAGENES Y MODELOS 3D/4D.

SCIENTIFIC DOCUMENTATION, CONSERVATION AND PRESERVATION OF CULTURAL HERITAGE REQUIRES EFFECTIVE TECHNICAL SOLUTIONS THAT PROVIDE ACCURATE AND VERIFIED INFORMATION ABOUT THE HERITAGE GOOD. IN THE ARCHEOLOGICAL FIELD, THE IMMENSITY OF THE COATS OR CAVES WITH PAINTINGS OF PREHISTORIC ROCK ART ARE EXPOSED TO A MULTITUDE OF ENVIRONMENTAL AND METEOROLOGICAL CONDITIONS THAT HINDER THEIR PRESERVATION IN COMPLEX AND DISPERSED ORROGRAPHIC ENVIRONMENTS IN SPACE. THE DOCUMENTATION OF THE COATS IS ARDUOUS AND DELICATE, NOT ONLY BECAUSE OF THE DIFFICULTY OF READING THE PIGMENT (STRONGLY ERODED AND WORN), BUT ALSO BECAUSE OF THE COMPLEXITY OF THE SUPPORT, THE HIGH NUMBER OF MOTIFS (SUPERIMPOSED OR NOT), AND THE STRONG LUMINIC VARIATION THAT AFFECTS THEM, MAKING IT DIFFICULT TO INTERPRET THEM (UNLESS THERE IS A GOOD PRIOR DOCUMENTARY BASIS). DIFFERENT TECHNIQUES HAVE BEEN USED OVER TIME TO DOCUMENT THE COATS, PASSING THROUGH DRAWINGS, DECALS, PHOTOGRAPHS, AND EVENTUALLY, DIGITAL DECALS, MULTISPECTRAL TREATMENT, ASIO AS THE GENERATION OF 3D MODELS USING LASER SCANNER AND/OR PHOTOGRAMETRIA. This PROJECT gives more than one step and proposes an unpublished SCIENTIFIC SOLUTION AND VANGUARDIA._x000D_ THIS PROJECT PERSIGUE TO INTEGRAT THE SPECTROFOTOMETRITE Aging ANALISIS, Colorimetria AND PHOTOGRAPHIC Multispectral Imagination CAPTURED MEDIANT DIGITAL CAMARA CALIBRATE (ESPACIAL AND Spectrally), in a SOLUTION TO PERMIT Identify AND MAKE AUTOMATically PIGMENTS WITH MAXIMAL FIABILITY IN LEVANTAGES/Models/TRIDIMENSIONAL Reconstructions (3D), OR 4D (INCLUDING THE VARIABLE TIME). THE INTEGRATION OF THE FOUR SPECTRAL, COLORIMETRIC, RADIOMETRIC AND SPATIAL COMPONENTS INVOLVES USING THE COLOR CHART AS A BASIC REFERENCE (PATRON), AND CONVERTING THE DIGITAL CAMERA INTO A PRECISION INSTRUMENT CAPABLE OF EXTRAPOLATING THE RADIOMETRICO CONTENT (PER BAND OF EACH CAPTURED IMAGE) IN COLORIMETRIC AND SPECTRAL VALUES. THESE VALUES WILL BE ANALYSED AND PROJECTED ON 3D OR 4D MODELS GENERATED FROM MULTIPLE CONVERGENT OR ESTEREOSCOPIC IMAGES. _x000D_ additionally, PLANTING THE MONITORISATION OF PIGMENTS TO THE TIME LONG (MEDIENT THE Aging ANALISIS), CONSIGUENTLY extrapolating to the Association of Openings/CUEVAS, WHERE YOU CAN be displayed and PRECTED YOUR FUTURE COMPORTATION (to the length of the SIGLOS VARIOS) on IMAGEN and MODEL PROPITS 3D/4D.
